1. Foam twice or thrice (optionally) after EPS material’s once pre-expanding. For those factories whose annual output of EPS material below 2000t, only one JF-1600C batch pre-expander is necessary to pre-expand heavy & light material simultaneously, which meets the production requirement, improves the production efficiency and saves space & energy.
2. Adopt KOYO Japan’s PLC programmable controller and 10’ real color touch screen in the electric system, easy to operate, running stably.
3. Use full-automatic spiral feeder & negative pressure feeder to feed, photoelectric controlling system & weighing module to ensure exact weighing.
4. Adopt YS Japan’s steam reducing valve in the steam system, strictly controlling the steam pressure in the chamber.
5. Use German proportional valve (optionally) to control the temperature difference in the chamber exactly within ±2℃ when the density of beads pre-expanded is above 20 kg/m3, ensuring the uniformity of foaming.
