1.The machine applies PLC and touch screen, automatic feeding, electronic weighting, temperature control, material level control to realize automatic production.
2. Electronic weighing system and material level control system assure the density of the foamed material, which make the granules uniformity and keep the density tolerance within ± 3%);
3. High precise guiding pressure reducing valve controls the temperature and steam pressure of the closed barrel to ensure the outcome pressure of the valve constant and the inner temperature controlled within ± 1%C, which keeps the foamed material equal and prevents the granule agglomerate because of the unstable temperature;
4. Automatic material controlling system, improving efficiency and reducing labor intensity
5. The closed type constant pressure foaming barrel has high heating efficiency, It can save more than 50% energy compared to the continuous pre-expander;
6. The machine is equipped with fluidized drying bed, it can dry, crush and filter the foamed materials automatically.
