The material composition of the bimetallic screw has a significant impact on its performance in the extrusion process, mainly reflected in the following aspects: 1. Wear resistance and life: The use of high-hardness, wear-resistant alloy steel can effectively extend the service life of the screw. Th... read more
1. Differences in structural design and torque bearing capacity Conical twin screw: The two screw axes are at an angle, the diameter gradually changes from the large end to the small end, the transmission gearbox has a large center distance, and larger bearings (such as tandem thrust spherical ball ... read more
1. High torque and large load capacity, adaptable to extreme working conditions The transmission system of the conical twin screw adopts a large-diameter thrust bearing design, which can withstand higher axial pressure and torque, especially suitable for the huge head pressure (usually up to 14-30MP... read more
1. Venting function The core feature of a venting screw extruder is that its barrel is equipped with a venting port, which can continuously remove volatile substances (such as moisture, air, low-boiling substances, etc.) in the polymer, thereby improving the quality and performance of the product. N... read more
1. Plastics processing industry: In plastic extruders, parallel twin screws and cylinders play a key role in melting, mixing and conveying plastic materials. Screws made of high-quality alloy steel can withstand high temperature, high pressure and corrosive substances in plastics, ensuring the stabi... read more
