Is a parallel twin screw extruder better or a conical twin screw extruder better? This is a question that users often ask when purchasing a twin-screw extruder. Parallel twin screw extruder Due to the small size of the center distance between the two screws, in the transmission gearbox, the space fo... Read More
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
The special screw is a high-viscosity non-crystalline plastic with poor fluidity. It is easily degraded when heated for a long time. It has a large feeding torque, difficult to melt, and is easy to block. It requires high material temperature and high pressure injection. The material temperature adj... Read More
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
