Introducing examples of process improvements in surface treatment (coating)! Successful increase in production by shortening molding time! What is the secret behind it!?
【Revealing Some Secrets of Our Successful Increased Production!】 ◆Concerns and Requests◆ In the molding process of a certain automotive part, there was a request to shorten the molding time to accommodate increased production. When attempting to demold the resin from the mold in a shorter time than usual, a problem occurred where the resin had not sufficiently hardened, causing the ejector pins to get stuck. However, this mold required strict dimensional control, with no allowance for even slight dimensional changes such as thermal distortion. The conventional Teflon coating had a high processing temperature of 400°C and did not provide sufficient dimensional accuracy, making it an unsuitable option. The surface treatment that solved this issue was 'Bicoat®'. ◆Background and Effects of Adoption◆ Among Bicoat®, "NYK-52-T" has a low processing temperature of around 200°C and excellent release properties, allowing for smooth demolding even with soft resin without sticking. It also offers good dimensional accuracy, with a coating tolerance of plus or minus 5μm. A major feature is that it can be applied to precision molds with strict dimensional requirements without worry!

basic information
The surface treatment technology, ultra-durable fluorine-based organic coating "Bicoat (R)," is a composite organic coating system that combines inorganic materials with high hardness, such as metals, ceramics, and chemical conversion coatings, with organic materials that excel in lubricity and release properties, such as fluororesins, siloxane resins, and super engineering plastics. It can be safely used even in molds that require micron-level dimensional precision, providing reliable release properties. 【Features】 ■ High hardness and scratch resistance ■ High dimensional stability ■ Excellent non-stick properties ■ Long lifespan ■ Excellent pressure resistance ■ Bicoat achieves both "toughness" and "non-stick properties" on the coated surface ■ Safe for use in molds requiring micron-level dimensional precision *For more details, please contact us or refer to the catalog.
