The extrusion screw barrel is an important component of the extrusion machine.
They are in charge of heating and melting plastics or other materials, and then pushing them into the mold head to form the desired shape and size. The screw rolls the material inside and brings it into the barrel, gradually melting it under the conditions of heating and rotation. The heating and cooling zones inside the barrel can control the temperature and viscosity of the melted material. The fit between the extrusion screw and barrel is crucial, as it directly affects the efficiency and quality of extrusion processing. Different extrusion processing requires different combinations of screw and barrel to meet the production requirements of different plastic products.
Therefore, the extrusion screw barrel and the extrusion machine are closely related and work together to achieve the production process of plastic products.
