In a certain automotive parts molding process, there was a request to shorten the molding time in order to accommodate increased production. ■Concern When attempting to demold the resin from the mold in a shorter time than usual, a problem occurred where the resin had not yet solidified sufficiently, causing the ejector pin to get stuck and not come out. Therefore, a coating that improves resin demolding was considered. ■Request This mold requires strict dimensional control, and under conditions where even slight dimensional changes such as thermal distortion are not permitted, the conventional Teflon (TM) coating was not selectable due to its high processing temperature of 400°C and insufficient dimensional accuracy. ■Challenges to be solved - Improvement of production efficiency - Reduction of defects - Shortening of work time ■Coating that solved the issue 'Bicoat (R)' *For details on how the issue was resolved, please download the PDF or contact us.

We would like to introduce a case of surface treatment that improved the adhesion issues of cutting tools used for cutting raw rubber. ■Concern Typically, when cutting tools come into contact with the material, their sharpness deteriorates. In the process of cutting soft and sticky raw rubber, if the sharpness of the tool decreases, defects such as burrs on the product occur. Reducing defects requires cleaning the tools, which is labor-intensive. ■Request For materials like raw rubber that are soft and highly adhesive, standard Teflon coatings are smooth and slippery, causing them to stick like a suction cup. Additionally, since cutting raw rubber is performed at temperatures around 200°C, a coating that can withstand that environment was necessary. 【Issues to be resolved】 - Product defects due to burrs - Adhesion of raw rubber - Heat resistance - Cleaning costs and labor expenses ■Adopted Coating 'TP Coating TP-411' *For detailed solutions, please download the PDF or contact us.

We would like to introduce an improvement case of an automatic label application device using robots. ■Issues In the label application process using robots, the labels peeled off from the release paper are placed adhesive side down on a platform, from which the robot picks them up and applies them to the products. However, there were frequent troubles where the robot could not smoothly peel the labels from the platform, causing work stoppages. ■Requests Initially, we tried a silicone coating with excellent release properties, but the silicone transferred to the labels, reducing their adhesive strength, which led to the labels peeling off after being applied to the products. Additionally, the conventional Teflon™ coating did not sufficiently prevent the labels from sticking. To solve this, it was necessary to achieve both excellent release properties and silicone-free performance. 【Issues to be resolved】 - Label peeling due to silicone transfer - Cleaning time for label adhesive - Line stoppage troubles due to sticking ■Adopted Coating 'Super TP 250 UNDER' *For more details, please download the PDF or contact us.

We will introduce a case of surface treatment that improved rubber sticking troubles in tire manufacturing equipment. ■Problem During the transportation process of tire manufacturing, when removing the donut-shaped rubber from the transport mold, the rubber stuck and could not be removed smoothly. This frequently caused line stoppage troubles, resulting in decreased production efficiency. As a solution, we tried a standard Teflon coating, but because the coating surface was smooth and slippery, the still-soft rubber stuck like a suction cup, proving ineffective. ■Request Silicone coatings and silicone release agents, which excel in release force, cannot be used due to the issue of silicone transfer interfering with the subsequent rubber bonding process. Therefore, a silicone-free release coating was required. ■Challenges to be solved - Release troubles - Line stoppage troubles - Decreased productivity ■Coating that resolved the issues Super TP Hemisphere Graphic HS How the issues were resolved can be found in detail by downloading the PDF or by contacting us.

Here is an example of surface treatment for device components that apply resist liquid to precision substrates. ■Consultation In the process of applying resist liquid to a film-like thin substrate, there was a consultation regarding the resist liquid adhering to the suction fixture during the application process to the precision substrate. ■Concern In the process of applying resist liquid to a film-like thin substrate, a problem arose where the resist liquid adhered to the suction fixture, causing the resist liquid from the fixture to stick to the substrate being transported next. The adhesion of resist liquid to the substrate leads to product defects, necessitating an increase in the cleaning frequency of the transport fixture, which in turn hindered productivity. ■Request To solve the problem, we initially tried prototyping with Teflon™ coating, but the slight surface irregularities of the coating transferred as patterns onto the thin substrate, resulting in product defects. A surface treatment that balances precision and prevents the adhesion of resist liquid was necessary for problem resolution. 【Issues to be resolved】 - Adhesion of resist liquid - Cleaning time - Variability in coating thickness ■Adopted Coating 'NanoProcess® TC-10' *For detailed solutions, please download the PDF or contact us.

We would like to introduce a case of surface treatment that improved the liquid drainage of measuring cups. ■Concern In the case of a standard measuring cup, liquid was drained by either tilting it at a steep angle or shaking it by hand. Particularly with heavy cream, the drainage was poor, requiring multiple shakes or the use of a spoon. Initially, we considered Teflon coating, but it did not perform well with heavy cream. ■Request When we received the consultation, the client was using a thin-film fluorine coating from another company, but there were many inconsistencies in the processing, and the liquid drainage was unstable, sometimes good and sometimes bad. ■Coating that solved the issue MRS-014 ■Background of adoption At Yoshida SKT, we produced a prototype of the MRS coating, which is a food-safe type with a thin film. By combining it with a special base treatment, we achieved good liquid drainage even with heavy cream. The ability to pour at a right angle also improved workability. The MRS coating is about 1μm thick, so there is almost no risk of volume error or foreign matter contamination. Additionally, at the World Bartender Championship, the ability to pour at a right angle was well received for making the actions look elegant. *For product details, please refer to the PDF.

We would like to introduce a case where we achieved prevention of adhesive residue on cutting blades when disposing of adhesive-laden packages. ■ Background of Surface Treatment Consideration In the device that removes products from the package, a mechanism was needed to automatically cut and dispose of adhesive-laden packages into smaller pieces. ■ What We Wanted to Achieve The device operates unmanned, with human intervention only required when the finely cut packages fill the dust box. Therefore, it was essential to prevent the adhesive from sticking to the cutting blades, allowing for maintenance-free operation. ■ Conditions for Selecting Treatment Initially, a fluororesin coating, effective in preventing adhesive residue, was selected and tested. However, the thickness of the fluororesin coating, approximately 30μm, caused a decrease in the sharpness of the blades. As a solution, we polished the coating only on the cutting edge and conducted retesting, but this resulted in the cutting edge being uncoated, leading to adhesive sticking. Continuous cutting of packages became impossible. ■ Adopted Coating 'MRS Coating' ▼ We are currently offering a free collection of improvement case studies and a coating trial set! ▼

■Concern This was a consultation regarding the transportation line where liquid-filled packs are conveyed by sliding them down a stainless steel chute. The issue was that the stainless steel chute and the liquid packs had poor sliding properties, causing the packs to stop midway and leading to line stoppages. Although a pusher was installed on the transport line to address this, it was inefficient, and improving the sliding properties of the chute remained a challenge. ■Background As a countermeasure, the customer polished the surface of the stainless steel chute with a buff and applied a fluororesin coating. While some improvement was observed, the process using the pusher did not change. Co-deposited fluororesin plating was also attempted, but it did not lead to any significant improvement. ■Adopted Coating "Super TP HL" ■Achieved Effect At Yoshida SKT, we proposed "Super TP HL," which can control surface shape using only fluororesin. After processing one of the actual chutes for testing, it began to slide without the use of a pusher. Currently, it has been adopted across all lines, and it is being used without any issues. *Product information PDF is available for download.

This is a case of surface treatment for equipment that transports eye drop bottles arranged in a line, which are dispensed from a prescription. ■Problems to Solve Eye drop bottles were being transported in a manner where they were pushed out one after another over the transport chute. However, on the flat metal surface of the chute, the bottles tended to stick and were difficult to slide, leading to blockages and tipping during transport. ■Goals to Achieve Due to the need for minimal human traffic in the sterile room, it was necessary to use the equipment for at least six months without maintenance, and a surface treatment that improves sliding was requested. ■Background for Coating Selection While fluororesin coatings, which have excellent sliding properties, initially performed well, the surface would become polished due to friction with the bottles. Once worn down to a flat and smooth state, the sliding ability decreased, leading to issues. Additionally, a method was considered where the substrate would be pre-treated to form a rough surface before coating, thereby reducing the contact area. However, since different metals such as aluminum and stainless steel were used for the chute substrate, variations in hardness led to significant changes in surface roughness, and difficulties in processing arose depending on the material. ■Adopted Coating 'TP Coating' ▼ Click here for details on the coating!

Here is an example of preventing plating adhesion to jigs used in the plating process. ■Concern In the process of applying electroplating to electronic components, plating was adhering to the jigs used to secure the products, resulting in time and costs for the peeling process. Additionally, when plating adhered, the jigs tended to deteriorate more easily, leading to an increased frequency of replacements. ■Coating Effect By providing insulation through our "fluororesin coating," the amount of plating adhesion to the jigs was significantly reduced. It also demonstrated excellent corrosion resistance, providing protection from plating solutions containing acids and alkalis. Furthermore, the lifespan of the jigs improved, and the amount of plating solution taken out was reduced. Our customers were pleased with the successful cost reduction. 【Key Points】 ■Purpose of Surface Treatment: Quality and operational stability, reduction of replacement and material costs, compliance with safety and environmental requirements ■Required Functions: Non-stick and release properties, rust and corrosion resistance, electrical properties ■Adopted Treatment: Fluororesin Coating (Teflon Coating) *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case study on surface treatment in the lamination process using hot melt adhesives for diapers and sanitary products. In the lamination process, if the applied adhesive adheres to the transport rolls, there is a risk of it transferring to the product or contaminating it, resulting in defective products. Therefore, it was necessary to regularly remove the adhesive. We adopted our "Super CTT" for this purpose. Thanks to its release effect, the semi-cured hot melt adhesive is transported without adhering, which reduces the frequency of cleaning, shortens cleaning time, and ultimately improves productivity. 【Key Points】 ■ Purpose of surface treatment: Speeding up, stabilizing quality and operation, reducing work loss ■ Required functions: Non-stick, release properties, wear resistance ■ Treatment adopted: Super CTT *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 decorative sheets to molds during transfer was eliminated. In the process of setting adhesive decorative sheets onto parts using molds and performing vacuum transfer, there was a phenomenon where the excess sheet outside the parts adhered to a part of the mold. To prevent the adhesion caused by the adhesive on the decorative sheets, our customer was exploring surface treatment for the molds. By adopting our "Bicoat," significant improvements in adhesion prevention were achieved. The adhesion of the decorative sheets was reduced to nearly zero, resulting in a level of satisfaction for our customer. [Key Points] - 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 [Achieved Effects] - By designing surface roughness and release effects tailored to the adhesive materials, which cannot be achieved with conventional fluororesin coatings or plating treatments, significant improvements in adhesion prevention were realized. - The adhesion of decorative sheets was reduced to nearly zero. *For more details, please refer to the PDF document or feel free to contact us.

Here is an example of surface treatment in the vulcanization process of rubber extrusion molding. In the manufacturing process of weather strips, extruded rubber was transported on rolls while being heated and dried in a furnace. Due to changes in the formulation of the rubber material 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 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. [Key Points] - Purpose of surface treatment: Quality and operational stability, reduction of work loss, compliance with safety and environmental requirements - Required functions: Non-stick and 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 will introduce a case study of trouble resolution on the transport line for electronic components sealed with resin. ■Issue The electronic components sealed with resin are suctioned by a jig and transported and placed on the substrate. However, there were instances where the slightly adhesive sealing resin would stick to the jig, negatively affecting the yield. ■Request Since the suction jig performs suction, transport, and placement operations tens of thousands of times per hour, high wear resistance was required. Additionally, an image recognition camera is used to confirm the position of the components on this line, so it was necessary to use a color that minimizes reflection to prevent whiteout in the images. ■Adopted Surface Treatment - Bycoat® NYK-01BK ■Background and Effects of Adoption 'Bycoat' was considered for preventing the sticking of the sealing resin and for its wear resistance. After evaluation on actual equipment, it was found to have good wear resistance as well as excellent release properties for the resin. 【Resolved Issues】 - Reduced sticking issues with the resin - Decreased cleaning costs - Improved productivity *For more details, please download the PDF or contact us.

We would like to introduce a case where product jams were prevented in the conveying guide of a frozen food automatic packaging machine. During the 20-hour daily operation of frozen food packaging, a phenomenon occurred where the side guide became a resistance to product conveyance, causing the line to jam. This resulted in the equipment stopping and the line halting, which was a significant issue. Additionally, there was a problem where the products were being scraped due to friction with the guide. By adopting the "Super TP Hemisphere HL," a large convex surface created a gap between the product and the guide, reducing sticking due to moisture and improving sliding. The situation where products jammed and the equipment stopped has been improved. [Key Points] - Purpose of surface treatment: Reduce work loss, stabilize quality and operation - Required functions: Non-stick and release properties, sliding and gliding, wear resistance - Adopted treatment: "Super TP Hemisphere HL" *For more details, please refer to the PDF materials or feel free to contact us.

■Customer's Concern A customer who manufactures pharmaceuticals such as laxatives reported an issue where, when filling products into containers shaped like tears and sending them on trays to the next process, the trays and containers had poor sliding, requiring significant force and time to push them out. ■Solution to the Problem By adopting the Super TP Hemisphere Graphic, we formed unevenness of fluororesin on the surface of the tray, improving its slip properties. As a result, products can be slid with much less force compared to the current trays, successfully reducing the workload. ■Coating that Led to the Solution Yoshida SKT Super TP Hemisphere Graphic

We will introduce a case where a problem that occurred in the production process of topical ointments was resolved. ■Issue A problem arose where the ointment components of the topical medication were sticking to the equipment. The cause of the problem was the adhesive nature of the ointment components. ■Background To resolve this issue, a highly non-adhesive coating was adopted. Specifically, a silicone-based MRS coating was used. ■Adopted Coating The MRS coating is so non-adhesive that it does not stick even to adhesives like tape. ■Effect of Adoption By adopting this coating, the sticking problem was resolved, leading to a reduction in defective products, an increase in the good product rate, and a decrease in maintenance time associated with line stoppages.

The fluororesin coating for plating jigs provided by Yoshida SKT Co., Ltd. addresses the challenges of quality stabilization and cost reduction in the electronic circuit board manufacturing industry. To overcome the deterioration and reduced insulation properties that were difficult to manage with conventional PVC-coated jigs, we adopted a special fluororesin coating. This coating offers superior processability compared to standard PFA coatings and allows for thick film processing. This results in the following advantages: - Increased lifespan: Achieves overwhelming durability compared to PVC coatings, reducing the frequency of jig replacements. - Reduced carryover of plating solution: Excellent water repellency prevents the carryover of plating solution to the next process over an extended period. - Stable insulation properties: Minimal deterioration from plating solution allows for long-term maintenance of insulation performance. - Total cost reduction: Although initial investment is higher, the increased lifespan of jigs and reduced maintenance frequency lead to long-term cost savings. As electronic devices become smaller and more high-performance, Yoshida SKT's innovative coating technology aims to enhance the performance and efficiency of plating jigs. *For more details, please refer to the PDF document or feel free to contact us.*
