Advantages of plastic extruders

The plastic extruder can be divided into two parts, the power part and the heating part. The power part usually uses a frequency converter to save the remaining energy of the motor. The heating part generally uses a cast aluminum heating ring to save energy to the greatest extent.

The plastic extruder completes all the above processes through a barrel with a screw and auger. The plastic pellets enter the barrel through the hopper at one end of the barrel, and then are conveyed to the other end of the barrel by the screw. In order to have enough pressure, the depth of the flight on the screw decreases with the distance from the hopper. The external heat and the 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 ports, multiple feed ports, special mixing devices along the screw, cooling and heating of the melt, or no external heat source (insulated plastic extruders), relatively variable gap between screw and barrel size, and the number of screws, etc. For example, twin-screw plastic extruders can make the melt more fully mixed than single-screw plastic extruders. In tandem extrusion, the melt extruded from the first plastic extruder is used as raw material to feed the second plastic extruder, usually used to produce extruded polyethylene foam.
