          Bimetallic Screw and Barrel

          As a leading enterprise in the field of new materials in China, AT&M has been committed to the research and development of high wear resistance and corrosion resistance alloy system in the field of plastic machinery for many years. At present, AT&M has provided customers with HIP all-alloy screw and bimetallic composite barrel in batch. Its annual production capacity is over 10000 sets, which can completely replace imported products.

          Features

          Compared with the traditional metallurgy process, such as casting, forging, the meterials made by PM-HIP has fine grain, uniform microstructure, and higher bonding strength with base materials. Therefore, the properties, such as wear resistance, strength and toughness have been enhenced significantly, which improved the service life of key parts in plastic machine ,such as screw and barrel.

          Typical Applications

          The high quality screw and barrel made by PM-HIP have been fully recognized by plastic machinery customers. Their service life of products is increased 2-3 times than that with ?high speed steel. The products are widely used in screw and barrel, the key parts of extruder and injection molding machine in the plastic machinery field.
