简体中文There are significant differences in the requirements for Screw Barrel structures for different types of sheet extrusion. This difference is mainly reflected in the aspects of pitch, thread depth, screw diameter, structure type and surface coating. First of all, the size and nature of the extruded sheet directly affect the selection of thread pitch and thread depth. Some sheets may require larger pitch and depth to increase the extrusion speed, while others need to be carefully balanced to ensure uniform and stable extrusion. out process. Screw diameter is another critical parameter, and larger sheet sizes may require larger diameter screws to provide adequate extrusion force and uniformity.
Different types of sheet extrusion may also require different screw construction types. For example, a single-screw structure is usually suitable for simple extrusion tasks, while a twin-screw structure can improve extrusion efficiency and is suitable for sheet extrusion that requires higher uniformity. In addition, the special properties and requirements of the panels may require customized surface coatings to increase wear resistance, reduce frictional resistance, or improve thermal conductivity.
It is also necessary to consider the working temperature of the extruded sheet, which involves adjusting the temperature control system of the screw barrel to adapt to the extrusion process requirements of different sheets. For some high-strength, high-viscosity sheets, a stronger and reinforced screw structure may be required to handle higher extrusion pressures and stresses.
