Fluororesin Coating 'HBA-838'

Explanation of Yoshida SKT's fluororesin coating 'HBA-838'.

There are various types of resin for fluoropolymer coatings, depending on the application environment. At Yoshida SKT, we specify materials and processing based on the product number. 'HBA-838' is a type of PFA coating. By processing it to a thicker film, it results in a coating without pinholes, making it suitable for applications that require corrosion resistance. 【What is PFA (Perfluoroalkoxyalkane Polymer)?】 PFA is an improved resin of PTFE, with the same continuous use temperature of 260°C. Its melting point is around 310°C, and it has a lower thermal melt viscosity than PTFE, allowing for a continuous film with fewer pinholes that could not be achieved with PTFE during coating. As a corrosion-resistant coating, it has the best performance among fluoropolymer coatings. Additionally, PFA can exhibit superior non-stick properties compared to PTFE depending on the substrate, making it widely used for non-stick and release coatings. *For more details, please download the materials or contact us.

Case study of mold release for molten metal: Coating that solved polypropylene stringing.

Reduce thread pulling during thermal welding of PP with surface treatment technology! Achieve long mold life!

■Consultation In our customer's process of thermally welding polypropylene products, issues such as thread pulling and adhesion to the welding mold have arisen. The welding mold required not only release properties but also heat resistance and thermal durability. ■Background and Effects of Surface Treatment Selection Our company considered a hybrid approach of ceramic-based CHC and fluororesin-based low contact area coatings to enhance release effects and prolong the lifespan of mold exchanges. We proposed "CHC-1311," which balances thermal hardness and reduced contact area. Currently, our customers are using it to achieve both release properties and long lifespan. If you are having trouble with the release properties of welding molds, please consult Yoshida SKT.

Case study on mold release for molten metal: Solving the stringing issue in battery cases through surface treatment.

We will introduce a coating case that solves the adhesion and stringing of resin that occurs during the welding process of the battery case container and lid.

■Concern In battery production, resin boxes and lids are welded together for sealing. The welding mold is made of aluminum and is heated to over 200°C for use. During this process, molten resin and stringing occur, which was addressed with a fluororesin (PTFE) coating. ■Background of Consultation with Our Company Due to the production of several thousand shots per day at temperatures above 200°C, the coating peels off in about a week. The hassle of changing setups for reprocessing and damage to the mold led to decreased production efficiency, prompting the consultation for improvements in surface treatment. ■Adopted Coating "CHC-1111CR" ■Adoption Background and Effects We proposed a newly developed "CHC-1111CR" that offers the same release properties as fluororesin coatings while maintaining high film hardness even when heated. Testing showed no stringing of the resin or peeling of the coating, allowing for use in tens of thousands of shots and achieving approximately three times the lifespan of conventional coatings. *For details on the coating, please refer to the PDF document.*

What is a method to reduce the release resistance of the ejector pin? Countermeasures through surface treatment.

Solve ejector pin troubles with surface treatment technology! Easy demolding even with soft resins that are less likely to stick.

■What is an ejector pin? Also known as a push-out pin, it is a pin incorporated into a mold to push out and remove molded products from the mold. Ejector pins are used in most injection molding molds and come in various shapes, materials, and sizes. It is important to choose the appropriate pin for demolding based on combinations of shapes such as round pins, square pins, and middle flange pins, as well as materials like SKD-61 and SKH-51. ■Methods to reduce the demolding resistance of ejector pins To reduce the demolding resistance of ejector pins, methods include mold design, pin arrangement and shape selection, and reviewing molding conditions. However, in cases of materials that tend to stick or soft resins, sticking can lead to demolding failures. In such cases, it is necessary to consider utilizing surface treatment technologies. ■Surface treatments to improve the demoldability of ejector pins Ejector pins need to protrude from the mold, so they require not only demoldability but also wear resistance and dimensional stability. Yoshida SKT's Bicoat has a proven track record of achieving smooth demolding when applied to ejector pins. For more details on Bicoat, please download the catalog and check.

List of surface treatments with excellent release properties.

This surface treatment is effective when you want to reduce adhesion, such as in mold release or heat plate release! We will introduce a surface treatment with excellent release properties.

"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.
