Explanation of measures against warping, distortion, and chipping caused by heat and blasting during fluororesin coating and PEEK coating.
In fluoropolymer coatings and PEEK coatings, substrate preparation is performed through high-temperature firing and sandblasting, which may cause deformation or damage in thin plates, thin-walled parts, and blade shapes. In particular, products with thin thickness or parts with edge sections are susceptible to the effects of thermal expansion and mechanical stress from blasting, which can lead to issues such as warping, distortion, dimensional changes, and chipping of cutting edges. When requesting fluoropolymer or PEEK coatings, we confirm the product shape, thickness, and material in advance, optimizing blasting and firing conditions. We propose processing specifications that take into account the risks of deformation and damage. If you are considering coatings for precision sheet metal parts or cutting tool components, please feel free to consult with us.

basic information
In fluororesin coatings and PEEK coatings, a surface preparation using sandblasting is performed to ensure the adhesion of the coating film, followed by the formation of the coating film through high-temperature firing at around 400°C. During this process, thermal and mechanical loads are applied to the substrate, which may cause deformation or damage depending on the shape and thickness of the material. Thin sheet products, precision sheet metal parts, mesh materials, punching materials, and cutting tool components are particularly susceptible to these effects, and issues such as warping, waviness, dimensional changes, and edge chipping may occur. Our company strives to balance quality and product protection by adjusting blasting conditions, reviewing surface preparation methods, optimizing firing conditions, and devising jig methods, taking into account product shapes and usage conditions.

Company information
Nikken Coating Industry Co., Ltd. has been a specialized manufacturer of functional coatings for contract processing, earning the trust of customers across various industries for 79 years since its founding. We leverage our processing technology to maximize the properties of fluororesins, such as non-stick, lubricity, and chemical resistance, providing high-performance coatings that directly address customer challenges, including "Thermo Pro Release" for thermal welding processes and "NonStick STC" for blades and precision molds. In recent years, in response to movements regarding regulations on fluorinated compounds (PFAS), "PEEK resin," which is gaining attention as a substitute for fluororesins, has become a focus. Nikken Coating Industry commercialized the world's first PEEK resin coating, "PEEKCOAT," in 1999. Based on the solid knowledge and know-how accumulated over more than 20 years, we are further intensifying our research and development efforts to explore the potential of next-generation PEEK coatings! We aim to be recognized as "the go-to for PEEK coatings" and will continue to lead the way. As "the best partner for functional coatings that builds trust through technology," Nikken Coating Industry will continue to contribute to the creation of high-quality, high-performance products.
