    What are the similarities and differences between parallel and conical twin screw extruders?

    Parallel and the conical twin-screw extruder have the same thing: it has a conveying mechanism that forces the plastic forward, good mixing and plasticizing ability and dewatering ability, and basically the same adaptability to the material and plastic product molding process. The difference between... Read More

    1. PET special screw: for PET low viscosity, large specific heat capacity, easy-to-stick materials and PET preforms that require fast plasticization and uniform plasticization, the screw has good plasticization, high stability, non-stick materials, and fast melting speed. The finished product rate i... Read More

    What is the difference between ordinary screw and alloy screw? (2)

    Flame hardened surface or high frequency brittle hard Surface hardening is a convenient processing method for cheap noodles. The hardness after quenching can reach about HRC55, and the quenching depth can reach 2–3mm. When flame hardening is used, the screw material can be 40Cr or 45 steel, so it is... Read More
