Screw/ Screw Assembly parts

Nowadays, more and more new innovative plastic materials are used in plastic industries. These plastic materials are highly corrosion and create huge damage on screws. In order to overcome this, TAI STAR do more effort on research different type of screw e.g. PTA bimetallic alloy screw, WC spray coating screw, Full hardening powder metallurgy (PM) screw. Recently, we take more research on Ceramic screw which is especially for halogen free material. This can enhance the life time of screw and bring more benefit to our customer.
