Description

Technical Field

[0001] The utility model relates to the technical field of plastic extruders, in particular to a double-screw extruder for plastic processing. Background Art

[0002] Plastic processing is also called plastic molding processing. It is a general term for various processes that convert synthetic resins or plastics into plastic products. It is a large production department in the plastics industry. Plastic processing generally includes plastic batching, molding, machining, joining, modification and assembly. The last four processes are carried out after the plastic has been formed into finished products or semi-finished products, also known as plastic secondary processing. In plastic extrusion molding equipment, plastic extruders are usually called main machines, and the subsequent equipment plastic extrusion molding machines that match them are called auxiliary machines. After more than 100 years of development, plastic extruders have evolved from the original single screw to twin screws, multiple screws, and even screwless models. Plastic extruders (main machines) can be matched with various plastic molding auxiliary machines such as pipes, films, holding materials, monofilaments, flat wires, strapping tapes, extruded nets, plates (sheets), profiles, granulation, cable coating, etc., to form various plastic extrusion molding production lines and produce various plastic products. Therefore, we designed a double-screw extruder for plastic processing. Utility Model Content
