Classification：
The application of the structural form of the barrel is divided into: integral, segmented, bushing, casting, and bimetal layered barrels.
Integral barrel: In the case of injection molding machines and extruders, the most suitable ones are monolithic barrels, especially small and medium-sized models, which basically adopt this type of structure. The barrel is generally used for 38CrMoALA. Moreover, the temperature control is accurate and easy, and the machining accuracy is relatively easy to ensure.
Segmented barrel: Mainly used in larger format extruders and exhaust type extruders. Since the total length of the barrel is divided into several sections, the machining of each barrel is convenient, and the temperature control of heating and cooling is relatively large.
