A wide range of plastic machinery. According to the processing technology, it can be divided into three categories: extruder, injection molding machine and blow molding machine.

The extruder extrudes the molten plastic through a fixed-shaped extrusion port under the action of a screw, and is cut by a water-cooled setting under the action of a tractor. Mainly used for a large number of continuous production of the same cross-section products, such as pipe \ rod \ profile, etc., can also be used for plastic modification granulation.
The basic mechanism of extrusion is simple - a screw rotates in the barrel and pushes the plastic forward. The screw is actually a bevel or slope, wrapped around the center layer. Its purpose is to increase pressure in order to overcome greater resistance. For an extruder, there are three types of resistance that need to be overcome: the friction between the solid particles (feed) against the drum wall and the mutual friction between the solid turns (feed zone) and the first few turns of the screw; Adhesion on the cartridge wall; resistance to the internal flow of the melt as it is pushed forward.
Divided into single screw extruder and twin screw extruder.

Injection molding machine
An injection molding machine injects molten plastic into a mold and cools the product.  Servo injection molding machine The use is very extensive, depending on the plastic, the use of different places. Injection molding machine is the largest processing machine used in the plastics processing industry, not only has a large number of products
Injection molding machine
Injection molding machine
It can be directly produced by an injection molding machine, and it is also a key equipment for the injection blow molding process.
