Working Principle of Plastic Pipe Extruder

As an important equipment for plastic pipe forming, the plastic pipe extruder transports, compacts, melts, and shears plastic through external power transmission and heat transfer from external heating elements.

The plastic pipe extrusion line is also constantly improving and improving. During operation, heating, pressurization, and shearing are used to transform solid plastic into a uniform and consistent melt, and the melt is sent to the next process. The production of the melt involves mixing additives such as masterbatch, blending resins, and re crushing. The finished melt must be uniform in concentration and temperature. The pressure must be large enough to extrude the viscous polymer.

The extruder completes all the above processes through a barrel with a screw and a spiral channel. Plastic pellets enter the barrel through a hopper at one end of the barrel and are then transported to the other end of the barrel through the screw. In order to have sufficient pressure, the depth of the threads on the screw decreases as the distance to the hopper increases. External heating and internal heat generated by friction between plastic and screw cause plastic to soften and melt. Generally, different polymers have different applications. Plastic extruders are designed with exhaust outlets, multiple feeding ports, special mixing devices along the screw, cooling and heating of the melt, external heat sources, relative changes in gap between screw and barrel, and the number of screws.
