Classification Of Injection Molding Machines

1) Classified by plasticizing method

1. Plunger Plastic Injection Molding Machine

Its mixing performance is very poor, and its plasticizing property is not good, so a shunt shuttle device should be installed. Has rarely been used.

2. Reciprocating screw plastic injection molding machine;

Relying on the screw for plasticization and injection, the mixing and plasticizing properties are very good, and it is used most.

3. Screw—Plunger plastic injection molding machine relies on the screw for plasticization and the plunger for injection, and the two processes are separated.

2) Classified by mold closing method

1. Mechanical

2. Hydraulic type

3. Hydraulic-mechanical
