      Injection molding machine screw & barrel category: 

      The barrel can be divided into integral type, sectional type, bushing type, casting type, and bimetallic type.

      Integral type barrel:

      It is the most used barrel in injection molding machines and extruders, especially for small and medium sized machines.

      The barrel usually made from 38CrMoALA, it can control the temperature accurately, and the processing precision can be guaranteed.

      Sectional type barrel:

      It is mainly used in large extruders and air-vented type extruders. Because the barrel has several sections, the processing is much easier, but the temperature control error is relatively bigger.
