After many times experiment,our company develop a new type EPS pre-expander.Its success symbolizes a new technology top of our factory manufacturing EPS machine.This new pre-expander has several new features.The volume is smaller to make full use of limited area,its operation performance is improved.The application range of this EPS pre-expander is widely,it is suitable for both small amount productionand batch production.It also can be used for different foaming rate from low to    high.

Main features

--- Adopted PLC Controller and Touch Screen to realize automatic circulation of Automatic feeding, electronic measurement and automatic control of barrel temperature and pressure, drying.

--- Computer control system for easy operation and intelligent memory.

--- This machine is especially suitable for EPS production in highland anoxia area,playing

its own advantages.(Compared with low production efficiency of continuous pre-expander

in same condition).

--- High precision of measurement system guarantees feeding accuracy.

Automatic blower improves discharging speed.

--- High quality enclosed constant pressure foaming,high thermal efficiency.

About 50% energy-saving than continuous pre-expander.

--- Used photoelectric control foaming material level&capacity,reaching the uniform of foamed beads density.

--- High quality enclosed drying system (optional).
