Weifoer eps styrofoam batch expanding machine

Main advantage:

1. Fully automatic and intelligent prodcution;

2. Human-machine cooperation, controlled by PLC and color touch screen, easy to operate;

3. Accurate density, high output and energy-saving

4. Smooth operation and stable


Function Description:

1. This machine accept PLC and color touch screen control, automatic feeding, automatic control barrel temperature and pressure, automatic sensor testing material;

2. The barrel is made by stainless steel, realize constant pressure foaming;

3. Control barrel temperature and pressure by Japanese imported pressure reducing valve and Germany imported proportional valve;

4. Using famous brand electrical components and pneumatic components, to ensure the machine running stable and smooth operation;

5. Using the photoelectric to control the expansion material volume,making the expansion density uniform;

6. Automatic discharge the material, by using fan to blow material, increase the discharge speed;
