A pneumatic injection molding machine works through the following steps:
Clamping
- The machine uses a pneumatic clamping system. Compressed air drives a piston - cylinder mechanism to generate the clamping force. This force closes the mold halves together with a certain pressure to ensure they remain tightly closed during the injection process.
Injection
- Compressed air powers a hydraulic cylinder that drives a plunger or screw. The plunger or screw pushes the molten plastic from the hopper through the barrel and into the mold cavity. The amount of plastic injected is precisely controlled by the movement of the plunger or screw, which is regulated by the pneumatic - hydraulic system.
Cooling and Solidification
- After injection, the mold remains closed, and the plastic in the cavity cools and solidifies. This is usually facilitated by a cooling system that circulates water or other cooling media through channels in the mold.
Ejection
- Once the plastic part has solidified, the pneumatic system activates an ejection mechanism. This mechanism uses compressed air - driven pistons to push the finished part out of the mold cavity, allowing it to be removed from the machine for further processing or quality inspection.
