(1)Classification according to the plasticizing method
1. Plunger-type plastic injection molding machine
It's mixing is very poor, and plasticizing is not good, and should be equipped with a diversion shuttle device. Has been rarely used.
2. Reciprocating screw plastic injection molding machine;
Relying on the screw for plasticizing and injection, mixing and plasticizing are very good, and now use the most.
3. Screw - plunger type plastic injection molding machine rely on the screw for plasticizing and rely on the plunger for injection, the two processes separately.
(2) According to the mold closing method classification
1. Mechanical
2. Hydraulic
3. Hydraulic - mechanical type
The injection molding machine is also known as injection molding machine or injection machine. It is the thermoplastic plastic or thermosetting plastic using plastic molding molds made of various shapes of plastic products of the main molding equipment. Divided into vertical, horizontal, all-electric type. Injection molding machine can heat the plastic, the molten plastic to apply high pressure, so that it is shot and filled with mold cavity.
