We are a high-technology company developing and manufacturing the polymer composites and products especially on the field of the manufacturing and using compressor. The main products include: (1) The plastics valve sheet manufactured using PEEK composite for piston compressor. (2) The star wheel sheet manufactured using PEEK composite for single-screw compressor. (3) The all kinds of seal rings used in high temperature or oil-free environment for piston compressor. (4) The special machine parts which use in high temperature, high pressure, acid, base corrosion environment. The company has abundant experiment on the design, process, manufacture and application of special polymer composite such as polyetherether ketone (PEEK) , polyimide (PI) and so on. The ability of designing composite, moulding composite, precision mechanism processing, measuring property of the company supplies the base for the quality of the products.
