Screw Barrel for Injection Molding Machines
产品介绍
Technology Parameter:
Material: the surface tungsten carbide ultra-sound overall spray can improve the wear resistance of the screw
Heat-treatment: Vacuumhardening heat treatment process can greatly improve the service life of the three small pieces.
While emphasize the development and retainment of high performers, we introduce a series of modern facility and continuously improve our quality control system.Adhering to the customer service philosophy, we keep exceeding customers' expectation as our pursuit.
