■Concerns Lead-acid batteries, widely used in automobiles and commercial power sources. In the production process, after filling a resin box with electrodes and other components, the container and lid are welded to seal them. The heating plates used for welding are made of aluminum and are heated to over 200°C, but due to the occurrence of melted resin and stringing, a fluororesin (PTFE) coating was applied. ■Background In a production line that operates at temperatures above 200°C and produces several thousand shots a day, the coating on the heating plates peels off in less than a week. Reprocessing the coating has caused issues such as the hassle of changing setups and damage to molds, leading to decreased production efficiency. ■Adopted Coating "CHC-1111CR" ■Adoption Background and Effects Therefore, we proposed the newly developed "CHC-1111CR," which has equivalent release properties to fluororesin coatings and high hardness of the coating film during heating, making it resistant to peeling and wear. Testing on the actual line showed no stringing of the resin and no peeling of the coating, allowing for use in tens of thousands of shots and achieving a lifespan approximately three times that of conventional coatings. *For more details, please refer to the PDF document.*

■Concern For customers manufacturing resin containers made of PP (polypropylene), there was a process of adjusting the size and welding them in the middle for containers that are split vertically into two parts. ■Background To prevent adhesion of PP on the heat welding plates (heater plates) used for welding PP resin, PTFE coating (fluororesin coating) was adopted. The heater temperature is high, reaching up to 250°C, and since it is pressed against the PP resin during use, the PTFE coating would get scratched, leading to delamination at the interface between the heat welding plate and the coating, necessitating immediate replacement. ■Adopted Coating "CHC-1111CR" ■Adoption Background and Effects While PTFE has high heat resistance and is less likely to soften when heated, we proposed "CHC-1111CR," which has even higher film hardness during heating. In actual machine tests, where PTFE could no longer be used after one cycle, it was found that it could now be used for four cycles, leading to its adoption. The adhesion prevention performance for PP remains unchanged compared to PTFE. *For more details, please download the PDF or contact us.*

■Concern The paper used for packaging liquids such as milk cartons is laminated with resin such as polyethylene on its surface. The adhesive used for the lamination process was causing issues by oozing out from the processed paper and sticking to the transport chute, leading to foreign substances adhering to the product (processed paper) and resulting in product defects. ■Background The customer we consulted was using an overseas-made device, which had surface treatment on the transport section since its introduction. Upon inspection, it was found that a fluororesin coating had been applied, but adhesive residue that oozed out from the paper was sticking and hardening, worsening the product's slip characteristics, necessitating frequent cleaning. ■Adopted Coating 'Super TP Hemispherical Graphic HL' ■Effects of Adoption The reduction in contact area of the 'Super TP Coating' and the excellent slip properties of the fluororesin successfully prevented the adhesion of adhesive residue. The smooth convex surface allowed for smooth transport without scratching the laminated paper. As a result, the need for regular cleaning has been eliminated, achieving both a reduction in product defects and an increase in production efficiency.

■Concern We received a consultation regarding a problem where a blade used to punch out polyurethane rubber shapes causes the device to stop due to fragments of polyurethane rubber sticking to the blade. Upon checking, we found that the device sometimes stops on the first shot, significantly reducing the production efficiency of the product. ■Background In the case of punching blades, both release properties to prevent polyurethane rubber from sticking to the blade and slip properties to cut through the rubber without resistance when the blade is pressed into the rubber are necessary. The customer considered a fluororesin coating that excels in both release and slip properties and contacted us. ■Conditions for Choosing Treatment During the hearing, we understood that maintaining the sharpness of the blade edge is necessary for the punching blade to maintain the product shape, and that this is difficult to achieve with a fluororesin coating. We also learned that the customer has been achieving results with silicone release agents as an improvement measure. ■Adopted Coating 'MRS-014' ▼ We are currently offering a free collection of case studies on blade improvements in cutting processes and a trial set! ▼

We will introduce examples of surface treatment in pillow packaging machines used for packaging food and pharmaceuticals. ■ Adhesion Issues with Heat Sealers The films used for pillow packaging vary in thickness and functionality depending on their application. In thicker packaging films that excel in preserving product quality, a resin that melts easily is used on the inner surface. When heat sealing, the resin on the sealing surface adheres to the heating part of the sealer, leading to issues such as product contamination. ■ Coating Used Bicoat "NYF-11-S" ■ Background and Effects of Adoption While plating treatment is often used to prevent adhesion on heat sealers, the soft, melted resin tends to stick to the heat sealer and does not come off. Fluororesin coatings were considered, but under high temperature and pressure conditions, there was a high risk of the coating peeling off, making it unsuitable for use. Yoshida SKT's Bicoat eliminates resin adhesion to the sealer due to its excellent release properties, and the high hardness coating with superior adhesion improves durability. This has led to a reduction in product defects and successful packaging using new materials. You can request a sample book of coatings suitable for sealers through the link provided.

We would like to introduce a case study of surface treatment for molds used in blow molding PET resin. ■Challenges In the molds used for blow molding PET bottles, a coating was applied to improve release properties, making it easier for the resin to detach after molding. However, with the previous coatings, there were instances where the resin, softened by heat, would slightly adhere and remain, potentially leading to cloudiness in the PET bottles, necessitating frequent maintenance of the molds. ■Effects of the Adopted Coating We adopted our "Super Bi-Coat NYK-01-F05." This coating maintains performance characteristics such as film thickness precision and hardness comparable to previous bi-coats while improving release and slip properties during high-temperature molding. It reduces resin residue on the molds and enhances the transparency of the PET bottles. 【Key Points of the Case Study】 ■Purpose of Surface Treatment Reduction of work loss, stabilization of quality and operation ■Required Functions Non-stick and release properties, sliding and slip properties, wear resistance ■Adopted Treatment 'Super Bi-Coat NYK-01-F05' *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case of surface treatment that solved troubles in the application process of hot melt adhesive. A certain customer's product is manufactured by bonding a surface material (film) with insulation material using hot melt adhesive. Since the product with applied adhesive could stick to the conveyor rollers during transport and cause entanglement, a petroleum-based release agent was previously applied to the rollers as a countermeasure. However, complaints arose in the market due to the residual release agent on the product. There was a need for a countermeasure to prevent roller entanglement that could replace the application of the release agent. Therefore, we adopted our 'Super Alloy Coating'. After approximately two years of use, there have been no troubles such as roller entanglement, and of course, complaints regarding the adhesion of the release agent in the market have also disappeared. [Key Points] - Purpose of surface treatment: Quality and operational stability - Required functions: Non-stick, release properties, wear resistance - Treatment adopted: Super Alloy Coating *For more details, please refer to the PDF document or feel free to contact us.

■Concern When molding rubber of different materials in layers, the products molded in the mold enter the vulcanization process while still in the shape of the mold. The products were made of materials that easily adhered to the mold, resulting in a phenomenon where they stuck to the mold and could not be removed after vulcanization. ■Background During demolding, strong forces are applied, so using standard fluororesin coatings posed a risk of peeling due to insufficient film strength. We recommended a Bi-Coat that excels in release properties and wear resistance, but the mold in question was made of soft aluminum and required surface treatment compatible with sulfur vulcanization, necessitating the selection of a Bi-Coat treatment that could adapt to both conditions. ■Coating Adopted Super Bi-Coat NYY-11-F05 ■Adoption Process and Effects We tested a Bi-Coat suitable for aluminum substrates and usable for sulfur vulcanization. Initially, demolding was good, but rubber adhesion began to occur within a short period. Therefore, we proposed and tested the "Super Bi-Coat NYY-11-F05," which excelled in release properties, achieving both initial demolding and sustained release properties. This led to its adoption. *Product data PDF is available for download.*

We would like to introduce a case where the adhesion of decorative sheets to molds during transfer was resolved. Decorative sheets with adhesive are set onto parts using molds and are then vacuum transferred. During this process, it was observed that excess sheets, aside from the parts, adhered to some parts of the mold. To prevent the adhesion caused by the adhesive of the decorative sheets, surface treatment for the molds was explored. By adopting our "Bicoat," significant improvements in adhesion prevention were achieved. The adhesion of decorative sheets was reduced to nearly zero, resulting in a level of effectiveness that satisfied our customers. [Key Points of the Case] - Purpose of Surface Treatment: Quality and operational stability, realization of development needs, reduction of replacement and material costs - Required Functions: Non-adhesive, release properties, long lifespan - Treatment Adopted: Bicoat(R) *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case where the adhesion of adhesive from packaging film to cutter blades was prevented. ■Concern In a certain packaging process, during actual production, packaging film with adhesive would stick to the cutter blades, causing cutting issues and misalignment, which frequently led to line stoppages. As a result, we were unable to achieve the production quantities calculated from the takt time. ■Effect of Coating We adopted our product "MRS-003." This allowed us to keep the processing temperature below 250°C, eliminating concerns about blade blunting. Additionally, due to the thin film of just 1 micron, the sharpness of the blade edge was maintained. 【Key Points】 ■Purpose of Surface Treatment: Quality and operational stability, speed enhancement, compliance with safety and environmental requirements ■Required Functions: Non-stick and release properties, long lifespan ■Adopted Treatment: MRS-003 *We are currently offering examples of improvements in adhesive troubles with cutting tools and processes.

The manufacturing process of weather strips involved transporting extruded rubber on rolls while heating and drying it in a furnace. Due to changes in the rubber material formulation for environmental measures and durability, it became necessary to process the rubber at higher temperatures than before, resulting in the rubber becoming sticky immediately after entering the furnace. When a common fluororesin coating was applied to the transport rolls, it was confirmed that the rubber stuck to them like a suction cup. By adopting our "Super TP Coating," we significantly reduced the sticking of the rubber and achieved a relatively soft contact surface. [Case Study] ■ Purpose of surface treatment: Quality improvement, operational stability, reduction of work loss, compliance with safety and environmental requirements ■ Required functions: Non-stick, release properties, long lifespan ■ Treatment adopted: Super TP Coating *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case study that addresses the challenges faced by customers struggling with resin adhesion to hot melt plates. ■Problem In the process of bonding resin parts such as ASA, ABS, and PC for automotive component manufacturing through hot melting, the target resin is melted at approximately 180-210°C using a hot plate fixture (heat plate) for hot melting, and then bonded with another part. You were looking for a coating to prevent the phenomenon of the hot plate sticking to the resin or the melted resin stretching like threads during the hot melting process. ■Adopted Coating - FSR Coating ■Effects of Adoption Compared to conventional PFA coatings, an improvement in the durability of the release effect when used at temperatures above 200°C and an increase in lifespan were observed. ■Case Summary - Purpose of Surface Treatment: Quality and operational stability, speed-up, reduction of work loss - Required Functions: Non-stick and release properties, heat and cold resistance, wear resistance - Adopted Treatment: FSR Coating (Fluoro Super Release) *For more details on the coating, please refer to the external link or feel free to contact us.

We will introduce a case that resolved the sticking of decorative sheets to molds during transfer. ■Background Decorative sheets with adhesive are set onto parts using molds and are transferred via vacuum. During this process, it was observed that excess sheets, other than those on the parts, would stick to certain parts of the mold. To prevent the sticking caused by the adhesive on the decorative sheets, surface treatment of the molds was being explored. ■Adoption of Coating and Effects By adopting our "Bicoat," significant improvements in preventing sticking were achieved. The sticking of decorative sheets was reduced to almost zero, resulting in a level of satisfaction from our customers. 【Key Points of the Case】 ■Purpose of Surface Treatment: Quality and operational stability, realization of development needs, reduction of replacement and material costs ■Required Functions: Non-stick and release properties, long lifespan ■Adopted Treatment: Bicoat *For more details, please refer to the PDF document or feel free to contact us.

Ultra-thin film fluorine coating 'Nano Process TC-10S' Prevents oil sludge adhesion on engine parts! ■Challenges - Oil sludge was adhering to automotive engine parts, hindering sliding and significantly reducing engine performance and lifespan. - To prevent sludge adhesion, high oil-repellent properties and heat resistance of 200°C were necessary for use inside the engine. - Conventional Teflon coatings, which excel in heat resistance, have a thick film that cannot meet the stringent dimensional accuracy required to improve engine combustion efficiency. ■Solutions - TC-10S has excellent water and oil repellency and can be processed to a thickness of less than 1μm. - It sufficiently accommodates the tolerances of engine parts without affecting engine function. - It maintains oil-repellent properties even in environments exceeding 200°C. ■Features of TC-10S Due to minimal dimensional changes and the ability to maintain optical properties, it enables processing in areas where fluorine resin coatings have been difficult, such as 'precision parts' and 'fields requiring high dimensional and surface accuracy.' *For case studies and detailed surface treatment information, please refer to the PDF document or feel free to contact us.

We will introduce a case where the ultra-thin film fluorine coating "Nano Process TC-10S" achieved liquid drainage of the resist and improved product defects. ■Challenge Points - When applying resist liquid to a film-like substrate, the resist liquid adheres to the suction jig, causing the jig's resist liquid to stick to the next transport substrate. - Adhesion of resist liquid to the substrate causes product defects. - To prevent resist adhesion, the frequency of jig cleaning has increased. - With Teflon coating, the surface irregularities are transferred as patterns onto thin substrates, leading to product defects. ■Solution Points - The thin film fluorine coating with a thickness of less than 1μm does not transfer surface irregularities to the substrate. - The release properties of the resist liquid are good, reducing the risk of liquid adhesion to the substrate. - Reduction in cleaning time for suction jigs. - Decrease in product defects. ■Features of TC-10S - It maintains optical properties with almost no dimensional changes. - It enables processing in fields that require "precision parts" and "high dimensional and surface accuracy," which were difficult to process with previous fluororesin coatings. *For details on the case and surface treatment, please refer to the PDF document or feel free to contact us.

We would like to introduce a case of a coating that resolved the sticking issues of melt film that could not be solved with fluororesin coatings. ■ Background of the Consultation A certain customer was handling a tray sealer that covers plastic trays with film. In the process of covering plastic containers with film, the film is melted and thermally bonded to the plastic container. The thermal bonding plate is heated to over 100°C, causing the film surface to melt. To prevent the film from sticking to the heating plate, a fluororesin coating was applied. ■ Background of Coating Selection Fluororesin coatings are often used for their excellent non-stick properties, but depending on the material of the film and the melting temperature, they were causing product defects by sticking to the heating plate. Additionally, the heating plate had small holes for vacuuming the film, which limited the options available. ■ Coating Adopted 'TP Coating' *Please scroll down for more details. *For more information, please refer to the materials or contact us directly.

■Concern In the process of removing burrs generated when molding rubber products by sucking them in with a vacuum nozzle, there is a stickiness due to the freshly molded products, which causes them to adhere to the inner diameter of the nozzle. Each time the nozzle gets clogged, it is necessary to stop the line and clean it, which decreases work efficiency and productivity. ■Background of the Request Initially, we tested fluororesin coating, but during the testing phase, we observed some adhesion on the surface. After repeating the tests several times, we found that the adhesion worsened progressively. 【Issues to be Resolved】 - Reduction of cleaning time - Improvement of productivity - Cost reduction ■Adopted Coating 'MRS-102' ■Effects of Adoption We proposed the 'MRS coating,' which has effects comparable to the release agents used in rubber molding. In tests, there was no adhesion, and we began prototype testing with actual nozzles. By coating the inner diameter, adhesion of burrs to the inner surface of the nozzle was eliminated, resulting in no downtime for removal work and successfully improving production efficiency. *For more details on the coating, please download the PDF or contact us.

■Consultation In the production process of cartridge filters, the adhesion of resin to the heat welding plate used for welding the products has been a problem. The products are completed by thermally welding polypropylene containers and lids, but PP resin tends to cause stringing and adhesion to the welding jigs, negatively affecting the product's airtightness, appearance, and production efficiency. Therefore, the heat welding plates required not only excellent release properties but also heat resistance and thermal durability. ■Background of Coating Selection In the prototype, in addition to the standard fluororesin coating, we proposed a contact area-reducing fluorine coating "TP-855." Since the welding process involved relatively low pressure, the release properties improved, making stringing and adhesion less likely. Additionally, it was used for a relatively long lifespan. ■History and Effects of Coating To further extend the lifespan of the release effect, we considered hybridizing the high thermal hardness CHC series with the contact area-reducing coating. Aiming for even longer lifespan, we proposed "CHC-1311," which balances thermal hardness and contact area reduction. Currently, there is no metal exposure due to wear, and it is being used effectively. If you are facing issues in the heat welding process, please consult Yoshida SKT.

■Concerns In the process of manufacturing display panels for TVs and other devices, sealing is done using UV-curable resin. However, the adhesive resin tends to stick to the jigs, leading to an increased likelihood of product defects. ■Requests The standard Teflon™ anti-adhesion coating results in a film thickness of several tens of micrometers, which causes fine irregularities to be transferred to the resin, raising concerns about the impact on products requiring precision. Additionally, the 400°C heat treatment during coating can cause warping of the jigs, and the UV light necessary for curing the sealing resin can compromise the adhesion of the coating, making it unusable. ■Solution Coating NanoProcess® TLS-200 ■Problem Resolution - Significant reduction in product defects due to prevention of resin adhesion - Improved precision leading to longer lifespan of jigs - Increased production efficiency *For details on the effects and background of the solution, please download the PDF or contact us.*

■Concerns We received an inquiry from a customer who is prototyping a new elastomer extrusion product. They wanted to resolve the issue of unstable production due to adhesion to the extrusion mold. ■Background for Coating Adoption Initially, the adhesion was so severe that it was impossible to form the product, but after adopting our surface treatment, they were able to prevent adhesion to a degree that allowed production. However, during continued mass production, it was discovered that defects due to the adhesion of eye mucus occurred after about a month of use. ■Selected Surface Treatment 'MRS Coating MRS-102' ■Selection Process and Effects To further address the defects, we proposed MRS-102. Although eye mucus did occur during testing, it did not adhere to the mold and could be easily removed, which helped suppress the occurrence of defects, allowing for continuous use for six months. *For more details on the adopted 'MRS-102', please refer to the materials or contact us.*

We would like to introduce a case study on the improvement of cutting equipment for OPP adhesive films used in lithium-ion batteries. ■ Key Issues - Problems occurred when adhesive residue from the pads that adhere to the adhesive surface during film cutting caused the line to stop. - Although a release surface treatment was adopted, its lifespan was short, leading to frequent replacements. - To prevent line stoppages, a large number of adhesive pads were prepared as a countermeasure. ■ Selection Process - We wanted to use commercially available blades for surface treatment. - It was necessary to select a surface treatment that would not change the cutting performance. - A long-lasting surface treatment was needed to prevent line stoppages and reduce cleaning frequency. ■ Adopted Surface Treatment 'Nano Process TLS-200' ■ Effects of Surface Treatment - Release effect that prevents adhesive residue from sticking to the adhesive film. - The lifespan is three to four times longer than the previous surface treatment, resolving the lifespan issue. - The frequency of adhesive pad replacements has decreased, leading to improved productivity. This release surface treatment for adhesive films contributes to increased productivity. *For detailed product information, please download the PDF or contact us.

When welding plastic, the plastic to be joined is melted using a heat welding plate to perform the welding. To achieve stable welding of plastic products, measures against stringing on the heat welding plate are essential. The CHC (Ceramic Hard Coat) technology can achieve both "non-stick properties" and "coating hardness at high temperatures" equivalent to conventional fluoropolymer coatings. The "release effect sustainability" of the heat welding plate helps improve the heat welding process. [Leaflet Adoption Case Content] - Achieving high-temperature release and long lifespan in the heat welding process of filter cases - Solving the "peeling" and "blistering" issues of fluoropolymer coatings on resin welding plates - The release effect from processing the heat fusion plate lasts three times longer than PTFE coatings *For more details, please refer to the leaflet that summarizes the product information and case studies.

We would like to introduce a case study from the process of cutting thin PP sheets used for clear files. ■ Key Points of the Issue - A problem occurred where the PP sheet stuck to the cutting blade, causing the line to stop. - The blade type is a shear type with two blades, similar to scissors. - When PP adheres, the cutting surface becomes rough, leading to product defects. ■ Background of Selection - Standard fluororesin coatings have a thick film that reduces cutting performance. - The non-stick properties of fluororesin may sometimes be insufficient to prevent sticking. - A thin, superior non-stick coating compared to fluororesin coatings is needed. ■ Effects of the Coating - Troubles that occurred every other day have ceased for a month and a half. - The coating protects the blade edge, reducing the risk of workers cutting their hands. - By reducing product defects, it eliminates material loss amounting to tens of thousands of tons annually. Non-stick coatings for blades contribute to increased productivity, cost reduction, and improved safety. You can download a collection of case studies on cutting process improvements.

We would like to introduce a case of non-stick coating for aluminum vapor-deposited film sealing machines. ■Problem You were troubled by the issue of resin that overflowed from the film sticking to the sealer during thermal sealing. ■Background Initially, you were using a PTFE fluoropolymer coating, but the sealer surface was knurled, causing the coating to wear off and adhesion to occur within about two months. This resulted in production losses due to the need to stop the machine and replace the sealer. ■Adopted Treatment FSR Coating (using CHC technology) ■Effect of Surface Treatment The 'HR-1372AP' was adopted, which exhibits non-stick properties equivalent to fluoropolymer coatings at high temperatures above 200°C, and has high thermal hardness, resolving the wear issue. You can now use it for more than twice the previous duration. *For more details on the surface treatment, please refer to the materials or feel free to contact us.

■Consultation This was a consultation regarding the process of thermally welding filter cases to products. We create products by thermally welding polypropylene containers and lids, but PP resin tends to cause stringing and adhesion to the heating plates, which negatively impacts the product's airtightness, aesthetics, and production efficiency. Therefore, it was necessary for the thermal welding plates to have release properties, heat resistance, and durability. ■Background for Coating Selection We proposed fluororesin coatings and reduced contact area fluorine coatings during prototyping. Since the operating pressure is relatively low, the release properties improved, making stringing and adhesion less likely, allowing for relatively long service life. ■History and Effects of Coating To achieve even longer service life, we proposed "CHC-1311," which balances heat hardness and reduced contact area. After practical testing, it was adopted, resulting in reduced metal exposure due to wear, allowing for extended use. If you are having trouble with thermal welding jigs, please consult Yoshida SKT.

We would like to introduce a case where we solved the sticking trouble of the melt film that could not be resolved with fluororesin coating. ■ Background of the Consultation The consultation was regarding a tray sealer that covers plastic trays with film. In the thermal fusion process of sealing film onto plastic containers, the heating plate is heated to over 100°C, causing the surface of the film to melt. Initially, the heating plate was coated with fluororesin to prevent the film from sticking. ■ Background of Coating Selection The material of the film and the temperature at which it melts were causing product defects due to sticking to the heating plate. Additionally, small holes were drilled in the heating plate for vacuuming the film, which limited the options for coating. ■ Coating Adopted "TP Coating" ■ Adoption Background and Effects To accommodate many conditions, we proposed a release-type coating that excels in release properties compared to the current coating and does not hinder vacuuming, while also reducing contact area. The "TP Coating," which has good release properties and does not affect vacuuming, was adopted. *For more details, please refer to the materials or contact us directly.

■Concern In the heat plate welding of polypropylene sanitary products, thread pulling is likely to occur, making a non-stick (release) coating on the heat plate essential. The customer was using a PFA coating, but it deteriorated quickly, requiring the heat plate to be replaced in about a week. ■Background In this case, where repeated contact/release with components occurs at high temperatures, the effectiveness of the coating diminished rapidly. Replacing the heat plate and reprocessing the coating requires adjustments to the equipment and preparation of spare parts. A coating that excels in non-stick properties and lasts longer in high-temperature environments was needed. ■Adopted Coating FSR (Fluoro Super Release) HR-372AP ■Adoption Process and Effects Yoshida SKT prepared several samples, including the "FSR coating," which was developed with the concept of excellent release properties at high temperatures. Before the actual machine test, we confirmed the release properties of these samples at our company, and it was decided to conduct a practical test with the "FSR coating," which has a proven track record in high-temperature environments. The release effect lasted over five times longer compared to the previous PFA coating. The lifespan of the coating was excellent, and it was adopted.

■Concern Due to the different moldability of biodegradable plastics compared to regular plastics, there were issues with mold release in the prototypes, leading to molding troubles. ■Background We received this consultation because there is no track record of surface treatment with the materials being molded, and we do not know the appropriate surface treatment. ■Coating Adopted Bicoat Exceed NYK-2000E ■Adoption Process and Effects At Yoshida SKT, we prepared a collection of samples suitable for mold release from molding molds, and confirmed the release properties with actual plastics. We processed the well-performing NYK-2000E into the prototype mold, and it has been used without issues for several months. *Detailed surface treatment materials can be downloaded as a PDF.

Introduction of release (non-adhesive) coating for plastic carrier tape transport reels! ■Concern - Adhesive was sticking to the transport reels that wind the carrier tape, requiring cleaning with solvents each time they were used. There was a need to reduce the burden of solvent exposure for workers and to streamline the cleaning process, prompting consideration of surface treatment. ■Surface Treatment Solution 'MRS Coating' MRS-200 ■Points for Treatment Selection - Can be processed on plastic reels at temperatures below 80°C - Excellent release properties with minimal adhesive adhesion - Release effect is sustained even during solvent wiping operations *For more details on the case, please check our website! For more information on surface treatment, please download the PDF or contact us.

■Customer Request We want to eliminate stringing that occurs on the heating plate during the thermal welding of polyethylene containers.

■Consultation In our customer's process of thermally welding polypropylene products, issues such as thread pulling and adhesion to the welding mold have arisen. The welding mold required not only release properties but also heat resistance and thermal durability. ■Background and Effects of Surface Treatment Selection Our company considered a hybrid approach of ceramic-based CHC and fluororesin-based low contact area coatings to enhance release effects and prolong the lifespan of mold exchanges. We proposed "CHC-1311," which balances thermal hardness and reduced contact area. Currently, our customers are using it to achieve both release properties and long lifespan. If you are having trouble with the release properties of welding molds, please consult Yoshida SKT.

■Problems We Wanted to Solve We received an inquiry from a customer who wanted to resolve the issue of epoxy adhesive used for bonding parts overflowing and sticking to the transport plate. ■Conditions for Choosing the Treatment - Heat resistance of 150°C that can withstand the curing process - A tolerance of warping of less than 1mm to maintain precision - Silicone-free - Durable and washable ■Adopted Treatment TLS-200 (Nano Process) ■Achieved Effects After testing with samples and confirming with prototypes, it was adopted for mass production processes. If you want to prevent adhesion of epoxy adhesive, want to know more about the nano process, or are struggling with surface treatment in the precision field, please download the materials or contact us directly.

■Problems We Wanted to Solve We received a consultation regarding the accumulation of adhesive on the feed roll of a device that automatically applies tape, which caused line stoppage issues that needed to be resolved. ■Background / Conditions for Choosing Treatment Initially, a knurling process was implemented as a countermeasure, but it was not very effective.

To prevent troubles such as product jams and mispackaging that are likely to occur with packaging machines, the following features are required: ■ Wear Resistance Packaging machines need to operate for long periods to package food and pharmaceuticals, so surface treatments to improve the wear resistance of machine parts are necessary. ■ Corrosion Resistance Since packaging machines are used in the production lines of food and pharmaceuticals, surface treatments that are resistant to corrosion are required. ■ Dirt Resistance Packaging machines are used in the production lines of food and pharmaceuticals, so surface treatments that are difficult for dirt to adhere to are necessary. ■ Slipperiness Packaging machines need to transport food, pharmaceuticals, and packaging materials smoothly, so surface treatments with good slipperiness are required. Specifically, fluoropolymer coatings and Bi-Coat are selected. Fluoropolymer coatings improve slipperiness by coating the surface with fluoropolymer, while also providing high corrosion resistance and excellent dirt resistance. Bi-Coat excels in wear resistance, enhances slipperiness with non-stick properties, and improves dirt resistance. *You can download product information for "Bi-Coat(R)" in PDF format.*

Releaseability of a mold refers to the property that allows a product to be smoothly released from the mold. Poor releaseability can lead to issues such as prolonged release time or damage to the product. One effective method to improve releaseability is coating. Coating enhances non-stick properties and improves releaseability by forming a film on the surface of the mold. Depending on the type of coating, the characteristics such as the types of materials with excellent releaseability, durability, and wear resistance vary. Additionally, the appropriate coating differs based on the material and shape of the mold, as well as the type of resin being molded. "Bycoat" is a system that achieves the ideal function of "release + wear resistance" by combining "inorganic surface treatment technology" and "organic surface treatment technology." It withstands harsh usage areas such as injection molds, providing reliable lubrication and releaseability. Furthermore, due to its excellent dimensional accuracy, it is suitable for areas requiring micron-level precision. By processing with Bycoat, releaseability can be improved, reducing product defects and enhancing productivity. *Product materials and case studies are available for PDF download.*

This manufacturer was facing a problem in the manufacturing process of pain-relieving and anti-inflammatory adhesive patches (wet compresses), where products were sticking to the transport equipment, leading to line stoppages and product defects. The product consists of a three-layer structure, with an effective ingredient-containing paste layered on a supporting substrate and a release film. This paste was coming into contact with the transport guide, causing adhesion, which resulted in line stoppages and product bending defects. In response, we proposed the "MRS Coating," which excels in non-adhesiveness. This coating is effective even against adhesives like those found in duct tape. As a result of evaluations conducted with actual products and samples, it was confirmed that there was no sticking, and it was adopted for use in the actual machines. As a result, the sticking issues were eliminated, leading to a reduction in defective products, an improvement in the good product rate, and a decrease in maintenance time associated with line stoppages. Are you facing similar issues? The "MRS Coating" may contribute to improving the efficiency of your manufacturing line. Please feel free to contact us for more information.

In the manufacturing process of tear-shaped laxatives, when sending the products to the next stage by hand after filling, the sliding of the trays and containers was poor, requiring significant force and time. Therefore, a new surface treatment technology called "Super TP Hemisphere Graphic" was introduced. As a result, it became possible to slide the products with much less force. The workload was significantly reduced, allowing even workers with less strength to easily send out the products. This technology has already been adopted for improving the sliding properties of eye drop bottles, and its effectiveness has been confirmed. For those aiming to enhance efficiency in manufacturing sites, we encourage you to consider this. *For more details, please refer to the catalog or contact us directly.*
