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.

■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.*

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!

■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 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! ▼

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.

To prevent adhesion of sticky substances, fluoropolymer coatings (Teflon™ coatings) and silicone coatings are commonly used, but the following challenges may arise: [Challenge 1] Even with surface treatments claiming to prevent sticking, there was not much change. [Challenge 2] It started sticking unexpectedly quickly during use. [Challenge 3] Silicone coating transfers and causes defects in the bonding process (fluoropolymer did not provide sufficient effectiveness, leading to the choice of silicone). Recently, there has been an increase in customers needing solutions for more adhesive materials, such as wanting to release molten resins that do not fully solidify to shorten processing time. "Yoshida SKT has coatings that can improve such situations." With general fluoropolymer coatings, sticky substances can adhere due to various factors. In response, treatments that create a rough surface to reduce the contact area with sticky substances are known. Our company has a unique technology to create convex surfaces using fluoropolymer and is now offering a kit to experience its effects for free! ▼ You can apply from the official Yoshida SKT website below.

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."

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.

■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.

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.

Automotive parts number in the tens of thousands, and their manufacturing requires various facilities. Among them, resins, rubber, and elastomers have characteristics that make them easy to mold and are used in many exterior and interior parts. On the other hand, these materials can be difficult to handle due to their tendency to stick during molding and their low slip during transportation. Typically, designs are made to prevent troubles by innovating the shape and material of the equipment and molds, as well as the materials themselves, but issues can arise during prototyping or unexpected troubles can occur. Such troubles can be resolved through surface treatment. Surface treatment can change the surface characteristics of the base material, providing properties such as being less sticky, more slippery, and more resistant to wear. Below, we introduce surface treatments that have numerous achievements in the automotive parts field.

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.

Fluororesin, which excels in insulation, heat resistance, chemical resistance, and release properties, can be easily coated. It can be applied to cylindrical objects such as rolls and pipes, as well as rod-shaped and linear objects, by heating them to temperatures between 140°C and 200°C. With simple tools and a bit of experience, it can be applied on-site. Fluororescent heat shrink tubing allows for easy acquisition of the properties of fluororesin by heating and tubing it. *For more details, please refer to the PDF document or feel free to contact us.
