Composition of Main Machine
1. Extrusion System
It consists of a hopper and screws.
Plastics are plastified by the extrusion system into uniform melts which are extruded out of the machine head by the screws continuously at constant quantity and temperature under the effect of pressure resulting from the plastifying.
2. Drive System
It can offer torque and speed required by the screw.
3. Heating and Cooling System
It can be used to heat up or cool down the hopper (or the screw), enabling the molding process to be finished in the required temperature range
