40MM PVC Cable Extruder Machine High Speed Extrusion Line

Working principle of plastic extruder

By means of pressurization and shearing, the solid plastic is transformed into a uniform melt, and the melt is sent to the next process. The production of melt involves the process of mixed color masterbatch and other additives, mixed resin 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 plastic extruder completes all the above processes through a barrel with a screw and a spiral channel. Plastic pellets enter the barrel through the hopper at one end of the barrel, and then are transmitted to the other end of the barrel through the screw. In order to have enough pressure, the depth of the thread on the screw decreases with the increase of the distance to the hopper.

External heating and internal heat generated by friction between the plastic and the screw soften and melt the plastic. Different polymers and different applications often have different design requirements for plastic extruders. Many options involve discharge outlets, multiple feeding ports, special mixing devices along the screw, cooling and heating of the melt, or no external heat source (adiabatic plastic extruder), the relative size of the gap between the screw and the barrel, and the number of screws.

For example, the twin-screw plastic extruder can mix the melt more fully than the single screw plastic extruder. Series extrusion is a melt extruded from the first plastic extruder. It is used as raw material to supply second plastic extruders. It is usually used to produce extruded polyethylene foams.
