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.

"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.

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.

The "Super TP" release coating system improves the "release ease" of adhered materials through a technology that roughens the coating surface to a convex shape, thereby reducing the contact area. This achieves a level of non-stickiness that cannot be obtained with conventional Teflon or fluoropolymer coatings. It demonstrates remarkable release properties (anti-adhesion) even with highly adhesive substances such as unvulcanized rubber, adhesive tape, and hot melt adhesives. If you have been struggling with transportation issues or molding defects caused by adhesive materials, or if you need to reduce maintenance on molds, transport chutes, or rolls, please feel free to consult us. ■ Features - Non-stickiness and release properties that surpass fluoropolymer coatings - Anti-adhesion to adhesive materials like molten resins and adhesive tapes - Slip and lubrication properties through a special technology that roughens the coating surface - Compatible with silicone-free requirements (TP series, Super TP series) - Smooth release - Slippery (lubrication) (TP series) *For more details, please refer to the catalog or contact us directly.

Fluororesin lining is an important technology for protecting materials from damage caused by corrosion and chemicals. The main types of fluororesin lining include PTFE, PFA, and ETFE, each possessing specific properties suitable for particular applications and environments. Types of fluororesin lining: - PTFE lining: Excellent non-stick and heat resistance, with resistance to almost all chemicals. - PFA lining: Offers more options for processing methods compared to PTFE, accommodating various shapes of substrates. - ETFE lining: Combines strength and chemical resistance, with a wide range of substrate shapes that can be processed similarly to PFA. Fluororesin lining methods: - Sheet lining: A method of adhering fluororesin sheets to substrates, allowing for thicker linings. - Powder coating: A method of applying fluororesin as a powder coating and forming a film in a sintering furnace. - Rotolining: A method of applying lining material while rotating, forming a uniform film. It is suitable for use under harsh chemical conditions, such as in chemical plants and semiconductor manufacturing processes, and can protect materials over a long period.
