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.

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.

■What is the "Water Repellency" of Fluororesin? "Water/Oil Repellency" refers to the property of a material's surface to repel water and oil. A well-known example that illustrates this property is the lotus leaf. The lotus leaf utilizes this water repellency to keep itself clean and less prone to wetting, allowing for smooth photosynthesis. Teflon fluororesin also possesses this "water/oil repellency." For instance, even if a liquid tends to spread on a material, applying a Teflon fluororesin coating to the surface can impart water/oil repellency, causing the liquid to bead up and reducing its tendency to spread. You can find detailed information in the PDF document below. ---------------------------------------- 1. What is water/oil repellency? 2.

■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.*

"Release properties" refer to the ability of a mold to release from the cast, and it is often used with a similar meaning to non-stick properties. Non-stick properties refer to the characteristic of not adhering to or being difficult to adhere to strongly adhesive substances. Surface treatments with excellent release properties often use materials such as fluororesin and silicone, which have low surface free energy and, due to their molecular structure, possess properties that make them difficult to wet. Surface treatments that utilize such functions are effective for release applications, applications where adhesion needs to be minimized, and for simplifying cleaning. 【Selected Coatings (Partial)】 ■ Non-stick, slippery, heat-resistant - Fluororesin coating ■ Release properties, high hardness, dimensional stability (durable parts, molds) - Bi-Coat ■ Resin release at high temperatures - FSR coating ■ Prevention of adhesion of high-viscosity substances - Adhesive release coating - CTT fabric sheet - MRS coating (silicone-based coating) ■ Release properties, precision, water repellency, oil repellency, liquid runoff (precision parts, precision molds) - Nano process *For more details, please refer to the PDF document or feel free to contact us.
