The vertical injection molding machine is a mechanical device. Usually consists of injection system, clamping system, hydraulic transmission system, electrical control system, lubrication system, heating and cooling system, safety monitoring system and so on.
The injection system is one of the most important components of the injection molding machine. Generally, there are three main forms of plunger type, screw type and screw pre-plastic plunger injection type. Currently the most widely used is the screw type. The function is that, in a cycle of the injection molding machine, a certain amount of plastic can be plasticized and plasticized in a predetermined time, and the molten plastic is injected into the mold cavity through the screw at a certain pressure and speed.
Vertical injection molding machine is more suitable for insert molding of metal inserts,such as plastic knob, plastic nuts, etc.
