PEEK resin (polyether ether ketone) is a high-performance resin that possesses particularly high heat resistance, mechanical strength, and chemical resistance among super engineering plastics. Its continuous use temperature is around 250 to 260°C, and it can maintain stable performance even in high-temperature environments, leading to its adoption in a wide range of fields such as semiconductors, automotive, medical, and food machinery. In recent years, with the movement towards PFAS regulations, it has also gained attention as an alternative to fluoropolymer materials, and interest is increasing in applications that require "high durability" and "high reliability."

In fluororesin coatings and PEEK coatings, the firing process involves heating to around 400°C, which poses a risk of deformation and damage due to the expansion of internal air in hollow structures. Particularly in cases where sealed spaces are formed, such as in pipe structures, welded frames, hollow shafts, and box-shaped components, the internal pressure can rise during heating, potentially leading to bulging, distortion, coating defects, and rupture accidents. This article explains the necessity of "vent holes" that should be considered when coating hollow structures, as well as common design oversights that can easily occur. We will introduce important points not only regarding coating quality but also from the perspective of ensuring safety.

In fluororesin coatings and PEEK coatings, a coating film is formed through high-temperature firing, which imposes a significant thermal load on the substrate. Therefore, depending on the material and heat treatment condition, issues such as strength reduction, hardness changes, warping, and dimensional changes may occur. In particular, aluminum alloys, quenched steel, hardened materials, and welded structures are susceptible to thermal effects, and even slight deformations in precision parts can impact performance. This article explains the effects of high-temperature firing on the substrate and points to check in advance.

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.

In fluororesin coatings and PEEK coatings, the way the coating adheres varies depending on the shape of the substrate. In particular, at corners and edges, variations in film thickness are likely to occur, which can lead to issues such as coating cracking, peeling, and reduced corrosion resistance depending on the conditions. Special attention is required for corner pipes, bent sheet metal, and sharp edge components. Our company offers suggestions for R processing and optimizes coating specifications according to product shapes and painting methods, reducing variations in film thickness and the risk of coating defects. To ensure stable durability and chemical resistance, it is important to design shapes with coating in mind. If you have concerns about corner shapes, please feel free to consult us.

In fluororesin coatings and PEEK coatings, high-temperature heating is performed during the firing process, which may require "vent holes" for hollow structures. When heating in a sealed space, the internal air expands, increasing the internal pressure, which can lead to serious issues such as deformation or rupture. This article clearly explains the reasons why vent holes are necessary and the points to check during the design phase.

When applying fluororesin or PEEK coatings to aluminum alloys, it is important to be cautious of thermal effects caused by high-temperature firing. Particularly with age-hardened aluminum materials, re-heating can change strength and hardness, potentially affecting dimensional accuracy and mechanical properties. This article explains the mechanisms of thermal effects on aluminum substrates and countermeasures.

In fluororesin coatings and PEEK coatings, sandblasting is performed to ensure adhesion. However, for products with cutting edges or sharp edges, impacts from blasting may cause chipping of the cutting edge, edge deformation, or partial distortion. Especially for precision cutting tools and thin-edge shapes, even slight changes in shape can affect performance, making prior consideration important. Our company proposes processing conditions that take into account the balance between product protection and coating adhesion by adjusting blasting media, projection pressure, and changing substrate treatment methods. Please feel free to consult us when considering coatings for industrial cutting tools and cutter components.

In fluoropolymer coatings and PEEK coatings using electrostatic powder coating, the "Faraday cage effect" can make it difficult for paint to adhere to recessed or deep areas. As a result, there may be insufficient film thickness or pinholes, which can lead to a decrease in corrosion resistance and durability. On the other hand, paint tends to concentrate on protruding areas, which can sometimes cause cracking or peeling due to localized thickening. We optimize the coating conditions and film thickness specifications according to product shape and required performance, reducing the risk of film thickness defects. If you are considering coating for complex-shaped parts, please feel free to consult us.
