**Main Causes of Release Failure in Injection Molding** Release failure is a common issue in the injection molding process. It often arises from excessive adhesion between the mold surface and the resin. This problem particularly occurs with complex shapes or thin-walled parts, where the resin strongly adheres to the mold surface. Surface roughness and insufficient draft angles can also worsen release properties. Additionally, high temperatures of the resin during release can contribute to release failure. "Bycoat® NYK-01" is a high-performance surface treatment that suppresses resin adhesion and wear in injection molding, thereby improving productivity. Its special coating, designed for use in high-temperature environments, achieves approximately double the lifespan compared to conventional surface treatments. This reduces the frequency of replacements and contributes to lower running costs. It has a proven track record with automotive motor parts manufacturers and has led to regular requests due to its reliable coating technology. **Features** ■ Incredible durability ■ High hardness, resistant to scratches ■ Excellent wear resistance ■ Outstanding non-stick and release properties ■ Safe for use in molds requiring micron-level precision *For more details, please refer to the PDF document or feel free to contact us.*

Fluoropolymer refers to a type of polymer that contains fluorine atoms as a major component. Fluorine is a very distinctive element, and its properties are prominently reflected in the polymer. Below, I will explain the main characteristics and common applications of fluoropolymers in detail. ■Characteristics Very low adhesion Fluoropolymers are generally very smooth and have almost no adhesion, which is why they are known as "non-stick" or "non-adhesive." High chemical resistance Fluoropolymers possess excellent chemical resistance. They show resistance to many corrosive substances and solvents, and have chemically stable properties. This makes them suitable for applications such as chemical containers, piping, and gaskets. High heat resistance Fluoropolymers have the ability to withstand high temperatures. In particular, PTFE can endure very high temperatures (around 260°C or 500°F). This property makes them suitable for applications that require use under high-temperature conditions. Electrical insulation Fluoropolymers have excellent electrical insulation properties. This is one of the reasons they are widely used as insulating materials for electronic components and cables.

■What is Friction Friction occurs when two objects come into contact and move against each other, generating resistance on their surfaces. The force that arises during this process, which acts as a hindrance, is called frictional force. There are two types of friction: static friction and kinetic friction. The resistance force that acts until the objects start moving is called static friction, while the resistance force that acts after they start moving is called kinetic friction. ■Characteristics of PTFE Fluoropolymer PTFE has an exceptionally low resistance due to friction compared to other resins. The static friction coefficient of PTFE is about 0.04, allowing it to move two objects in contact with a small force. ■Low Friction Properties of Fluoropolymer (PTFE) Fluoropolymer (PTFE) has a low friction coefficient and is also used as a solid lubricant. PTFE has a structure where fluorine atoms tightly surround carbon atoms. The free energy of the fluorine atoms on the molecular surface is low, and the molecules exhibit extremely low polarity in their structural characteristics. This molecular structure is believed to influence the low friction coefficient of PTFE. ■Reasons for the Low Friction Coefficient of Fluoropolymer PTFE → Please check the basic information section for more details.

We would like to introduce a case study that resolved film adhesion issues that could not be solved with fluororesin coating on fusion molds. ■Consultation Details In the fusion process where a film is used to cover a container, the fusion mold is heated to over 100°C, causing the surface of the film to melt. Initially, fluororesin coating was applied to the mold to prevent film adhesion. ■Background of Selection Due to the material of the film and the melting temperature, film adhesion to the fusion mold was causing product defects. The mold has small holes for vacuuming the film, and there were limitations on options due to conditions such as not blocking these holes. ■Coating Adopted 'TP Coating' ■Adoption Background and Effects To meet the customer's usage conditions, we proposed a coating that has better release properties than the current coating and does not block the mold's holes, reducing the contact area. The customer adopted the "TP Coating," which has excellent release properties and does not affect vacuuming. *For more details, please refer to the materials or contact us directly.

• Food Packaging Machinery

Stainless steel is used in situations where products are packaged or transported. We introduce surface treatments that lead to solutions for challenges that could not be resolved by polishing the surface or embossing. ■Problems Occurring in Packaging Machines and Production Lines In packaging lines for food and pharmaceuticals, products are transported using stainless steel guides. Even if stainless steel is polished with a buff or embossed to facilitate product flow, there can be occurrences of line jams. ■Key Points for Problem Solving When using polishing materials for transport guides, if the surface becomes even slightly less slippery during high-speed and high-volume transport, products can jam, causing the equipment to stop. The slippery "fluororesin coating" allows products to flow at high speeds, but there are concerns about foreign matter contamination due to wear particles from the coating. In such cases, by adopting 'Bicoat,' which combines the hard coating of HV700-900 with the lubricating properties of fluororesin, we can achieve both wear resistance and slip properties, thus solving the issues of smooth product transport and surface treatment wear. *For product information on 'Bicoat(R),' please click on "PDF Download" or feel free to contact us.

Fluoroelastomers have C-F bonds in their copolymer structure, providing excellent chemical resistance, oil resistance, and durability among rubbers. A representative example is FKM. On the other hand, fluoropolymers are plastics that contain fluorine atoms in their structure, such as PTFE, FEP, and PFA. ■Differences in Characteristics 【Fluoroelastomers】 (FKM) They exhibit excellent resistance to petroleum-based oils and fuels. They are durable against ultraviolet rays and atmospheric pollutants, making them suitable for outdoor use. Generally, they can be used at temperatures up to about 230°C. 【Fluoropolymers】 (PTFE) They demonstrate resistance to many substances, including acids, alkalis, solvents, fuels, and organic materials with a high oxygen index. Due to their very smooth and highly non-stick nature, other materials are less likely to adhere to them. This is widely known as the characteristic of PTFE (polytetrafluoroethylene), which is famous under the trademark name Teflon. Fluoropolymers have excellent resistance to high temperatures and can typically be used at temperatures up to 260°C. *By applying fluoropolymer processing to fluoroelastomers, the surface can gain the properties of fluoropolymers.

■Difference Between Teflon and Fluoropolymer Teflon is a trademark of Chemours and is a brand name for fluoropolymers. Fluoropolymers include various types such as PTFE, FEP, PFA, and ETFE, but Teflon is a trademark for some of these. Teflon is a registered trademark of DuPont, represented by the 'R mark', while Chemours uses the 'TM mark'. Teflon-coated frying pans have popularized the term "Teflon coating" in society. Nowadays, the name Teflon is more well-known than the term fluoropolymer. Other chemical manufacturers also produce fluoropolymers, which are marketed under different product names. Industrial Teflon processing can be done at factories that have entered into licensing agreements with Chemours (DuPont). Yoshida SKT signed a contract with DuPont in January 1968 to become a Licensed Industrial Applicator (designated factory for industrial coatings).

Although it has a high melting viscosity, making injection molding difficult, it is used as a coating for frying pans and hot plates. ■Resin Name ETFE (Ethylene Tetrafluoroethylene Copolymer) ■Characteristics Unlike perfluorinated fluoropolymers, ETFE contains hydrogen atoms (H) in its molecular structure. Therefore, its chemical resistance and heat resistance are lower compared to PTFE and FEP, with a continuous use temperature of 150°C compared to PTFE's 260°C. On the other hand, ETFE has high mechanical strength and can be processed at low melting points, making it suitable for applications requiring corrosion lining and wear resistance. *For more details, please click on "PDF Download" or feel free to contact us.*

This is an introduction to a coating case for cutting tools used to dispose of packages with adhesive. ■ Background of Surface Treatment Consideration In the device that extracts products from packages, a mechanism was needed to automatically cut adhesive packages into smaller pieces for disposal. ■ What We Wanted to Achieve The device operates unmanned, and human intervention is only required when the dust box is full of finely cut packages. Therefore, it was necessary to prevent the adhesive from adhering to the cutting blade and to operate without maintenance. ■ Conditions for Choosing Treatment Initially, tests were conducted using fluororesin coating, which is effective in preventing adhesive adhesion. However, due to the film thickness of about 30μm, the sharpness of the cutting tool was reduced. As a solution, we polished the coating only on the cutting edge and performed retesting, but this resulted in the cutting edge being uncoated, leading to adhesive adhesion. Continuous cutting of packages became impossible. ■ Adopted Coating 'MRS Coating' 【Free Samples Available】 　▼ We are currently offering free samples of improvement cases for the cutting process and trial sets! ▼

■Chemical Resistance of Teflon / Fluororesin Teflon resin has high chemical resistance and does not dissolve, swell, or react with most acids, alkalis, and organic solvents. ■Reasons for the Excellent Chemical Resistance of Teflon / Fluororesin A major reason for the excellent chemical resistance of Teflon resin and fluororesin is its stable molecular structure. Teflon resin and fluororesin have a molecular structure where carbon atoms and fluorine atoms are connected in a linear chain. The bond energy of the carbon-fluorine (C-F) bond is very strong among chemical bonds, and furthermore, the C-C bond between carbon atoms is completely covered by fluorine atoms in a helical manner. Therefore, even when in contact with chemicals or solvents, they remain inert and do not degrade or dissolve as a resin, which means they have excellent chemical resistance. ■Products Utilizing the Chemical Resistance of Teflon / Fluororesin The chemical resistance of Teflon resin and fluororesin is used in various products in the chemical industry, semiconductor field, and medical and pharmaceutical sectors, such as: - Various gaskets - Packing materials - Pipes and hoses - Storage tanks - Reaction vessels - Heat exchangers *For more details, please download the materials or refer to the link below.*

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.
