Injection molding machine screw barrel is the heart of the injection molding machine, its use and maintenance is directly related to its life, the same screw some factories can use 8 years, some can only use 2 months, the same screw, why the difference is so big?

Injection screw is a long time in high temperature, high pressure, high mechanical torque and high friction environment, loss is inevitable. Even though the screw has undergone a variety of surface treatments, from quenching to nitriding, boriding to spraying, to double alloy spray, it seems that the quality of the screw itself has improved a lot.
