In semiconductor manufacturing equipment, the elution of trace impurities and foreign matter from component surfaces significantly affects product quality, making the cleanliness of coatings crucial. Traditionally, fluoropolymer coatings commonly use a primer layer to ensure adhesion; however, this multilayer structure can pose risks depending on the application. Our HYPERCOAT utilizes a unique vacuum technology to form a fluoropolymer coating directly on the metal substrate without the use of a primer, achieving high cleanliness. This reduces the risk of impurity elution from the primer and is suitable for clean environments. It also ensures practical levels of adhesion, making it promising for applications in advanced industries, including the semiconductor field. We can also consider and evaluate specifications based on the usage environment and required performance, so please feel free to contact us for technical consultations and prototype verifications.

PEEK coating has excellent mechanical strength and chemical resistance, but traditionally it has been difficult to ensure film thickness, with thick films generally being around 300 to 500 μm. As a result, there were limitations in durability in extremely harsh sliding environments, such as sliding parts subjected to high loads. Our company has adopted a layered process that repeats painting and firing multiple times, allowing for thick films of up to 3000 µm. This process achieves stable film formation while minimizing the risk of cracks and peeling due to internal stress and thermal expansion differences. The increased thickness makes it easier to secure wear allowances, contributing to the longevity of sliding and transport components. It can also be applied to applications that were difficult to address with conventional thin-film PEEK coatings.

In the process of sliding films and similar materials (feeding mechanism), the guide part of the feeding mechanism is coated with fluororesin to enhance slip properties and prevent adhesion. However, during transport, the workpiece (such as film) may stick to the guide, temporarily halting the line. This is caused by static electricity generated from friction between the resins, which causes the workpiece to adhere to parts like the guide and stop sliding. When this happens, the production line stops, necessitating recovery work. If this occurs frequently, it can lead to increased time and costs. Standard fluororesin tends to accumulate static electricity, but our static-dissipative fluororesin coating (Pass-e Coat) can release generated static electricity, thereby preventing workpiece adhesion due to static electricity. If you are experiencing issues with line stoppages caused by workpiece adhesion due to static electricity, please feel free to consult us.

• Processing Contract

Heat sealing (heat plate sealing) is a joining method where the parts of plastic components that need to be bonded are brought into contact with a high-temperature metal plate (heat plate) to temporarily melt the plastic surface, and then pressed together at the melted areas to integrate them. Some plastic pallets made of PP resin (polypropylene resin) are manufactured by integrating the upper and lower parts through heat sealing. The heat plates used in the heat sealing process of these plastic pallets are coated with fluororesin to utilize its property of being "non-stick," which helps prevent melted PP resin from adhering to the surface of the heat plate. However, over time, the fluororesin coating on the heat plate can become scratched or peel off, causing the resin to gradually start sticking. When resin adheres to the surface of the heat plate, the following problems can occur: - The resin is stretched from the adhered areas, compromising the appearance of the product. - Burnt resin that has stuck can mix into the joint area, leading to a decrease in the strength of the joint. - The need to replace the heat plate temporarily halts the production line, resulting in decreased productivity.
