Profile: Zhangjiagang Youcheng High-Tech Materials Co., Ltd. produces various polymer composite material products. Our products include general plastic products, including ABS, PP, PS and high polymer spray coating, including peek (polyether-ether-ketone), PI(polyimide), PEI, PES(polyether sulfone), PSU(polysulfone), and PPS(polyphenylene sulfide). Peek star wheel includes single screw compressor, and consists of 2 star wheels and 1 screw rod. Each star wheel has 11 cogs, and screw rod has 6 grooves. Screw rod drives the star wheel, and the rotation axles are perpendicular to each other. The ratio of revolution of screw rod and star wheel is 11:6. Star wheel is the core part of the single screw compressor. Compared to glass fiber reinforced plastics and composite materials, the wear resistance of peek strengthens 3-5 times than that of FRP and composite materials, and reduces the wear to screw rod. It is high temperature resistant, high humidity resistant, radiation resistant, chemicals resistant, and wear resistant.
