Causes of air leakage in PC hollow molding machine

The working principle of the pc hollow molding machine is similar to that of the injection device for injection. It uses the force of a screw (or plunger) to inject plastic with excellent plasticization (ie, viscous flow) into the closed cavity, and then the process is obtained after curing and forming. Injection molding is a cyclic process. Each cycle mainly includes: quantitative feeding-melt plasticization-pressure injection-mold cooling-mold opening. After taking out the plastic part, the mold is closed again and the next cycle is performed. Today, let us share some of the factors that cause the air leakage of the pc hollow molding machine

Causes of air leakage of pc hollow molding machine

1. The pressure of the sealed cylinder of the pc hollow molding machine is large enough. If the low-pressure sealed cylinder is selected, the low-pressure pressure can be kept below 8 kg, and there is no problem with the general water bottle. But it also depends on the high pressure and high pressure blowing soot pressure. If the pressure is too large, the downward pressure of the sealed cylinder will be blown to the bottle if the pressure is reduced. Leaking sealing gas. The pressure can be clamped automatically.

2. Whether the sealant of the pc hollow molding machine is damaged or sealed, if it deviates from the seal, it will leak.

3. The sealed cylinder or the seal is damaged. If the seal is damaged, it can be directly reflected. Open the solenoid valve of the sealed cylinder to understand.

4. The solenoid valve of the sealed cylinder is leaking or stuck or the exhaust is not smooth, which is also the reason for the leak of the cylinder seal.
