custom plastic injection parts:
An injection molding machine (injection molding machine) has two basic components: the injection unit for melting and feeding the plastic into the mold, and the clamping unit. The function of the clamping device is to:
1. Make the mold close under the condition of bearing the injection pressure;
2. Take the product out of the injection device to melt the plastic before it is injected into the mold, and then control the pressure and speed to inject the melt into the mold. Two designs of injection units are used today: screw preplasticizers or two-stage units, and reciprocating screws. Screw preplasticizers use a preplasticizing screw (first stage) to inject molten plastic into the injection rod (second stage).

The advantages of the screw preplasticizer are constant melt mass, high pressure and high speed, and precise injection volume control (using mechanical thrust devices at both ends of the piston stroke). These advantages are required for transparent, thin-walled articles and high production rates. Disadvantages include uneven residence time (leading to material degradation), higher equipment and maintenance costs.
The most commonly used reciprocating screw injection device does not need a plunger to melt and inject the plastic.
The types of injection molding machines are: vertical, horizontal, and all-electric, but no matter what kind of injection molding machine, there are two basic functions:
(1) Heat the plastic to make it melted;
(2) Apply high pressure to the molten plastic to make it shoot out and fill the mold cavity.
