Nippon Chemical Screw & Co, headquartered in Japan, recently approved Vestakeep for the manufacture of high precision one-inch sized screws. Vestakeep is the trade name of Evonik Industries for high temperature polymer polyether ether ketone (PEEK).
Application: semiconductor and pharmaceutical industries
The one inch-sized screw design is manufactured for various industries, especially semiconductors and pharmaceuticals, in the North American market.
Depending on the application, the PEEK material must fulfill different requirements. For example, in semiconductor manufacturing, a high purity is required. On the other hand, in pharmaceutical and food equipment sectors, the material needs to comply with drug or food contact requirements. In other typical industrial production lines, the material must also meet other specifications such as chemical resistance, high mechanical strength, or fatigue resistance. Other features of the PEEK material include high dimensional stability and ease of processing during injection molding processes.
