Product categories of plastic machinery:

February 20, 2023
There are many types of plastic machinery. According to the processing technology, it is divided into three categories: extruder, injection molding machine and blow molding machine.

The extruder is to extrude the molten plastic through a fixed-shaped extrusion port under the action of the screw, and then cut it after water-cooling and shaping under the action of the tractor. It is mainly used for mass continuous production of various products with the same cross-section, such as pipes\rods\profiles, etc. It can also be used for plastic modification and granulation.

The basic mechanism of extrusion is simple-a screw turns in a barrel and pushes the plastic forward. The screw is actually an incline or ramp that winds around the center layer. Its purpose is to increase pressure in order to overcome greater resistance. As far as an extruder is concerned, there are three kinds of resistance to overcome: the friction of solid particles (feed) against the barrel wall and the mutual friction between them during the first few turns of the screw (feed zone); Adhesion on the barrel wall; flow resistance inside the melt as it is pushed forward.

Divided into single-screw extruder and twin-screw extruder.
