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.
Adopt YS Japan’s steam reducing valve in the steam
system, strictly controlling the steam pressure in
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.
