The polystyrene molding machine has many improvements compared to the basic type shape molding machine and the features are as follows.
1. Machine structure:
a. All frame are welded onto 16/20mm steel plate with high machines legs. This greatly improves EPS moulding machine strength.
b. High machine legs are made by strong “H” type profile. It is easy for the client to install the machine (only prepare floor foundation).
2. Filling system: Adopts normal pressure, vacuum for high pressurized filling. Material filling is controlled by level sensor with double rotation chamber discharge and has 44 filling outlets.
3. Steam system: Adopts balance PID control valve with German gauge. This greatly improves steam accuracy and reduces consumption by around 20% compared with A/B type EPS shape moulding machine.
4. Cooling system: Big vacuum pump with vertical tank, equipped with vertical vacuum cooling water spray on the top. The vacuum cooling will be used as main cooling instead of water cooling (normally water cooling will be set up only 8-12s), which will keep the water content of product less than 10%.
5. Drainage system: Increased large for inlet and outlet of mould, adopts 8-1” inlet foe steam, ensuring fast cycle time,6/8-2” outlet for drainage system, 6” big drainage pipe is controlled by butterfly valve, Together they greatly increase heating and drainage speed of styrofoam moulding machine.
6. Control system:
a. Adopts PLC (Mitsubishi) and touch screen (Schneider) making operation easy.
b. All electronic components are from famous brands, which greatly improve the polystyrene molding machines stability.
c. The air cooling, steam, de-mould, pressure of filling are controlled by long-distance balance valve.
