EPS Foam Balls Pre-expander

A. main features:

1.This machine adopts PLC programmable controller and touching screen to carry out automatic production from feeding, temperature control, ration, pressurizing and feeding.

2.Top-grade sealing foaming with constant pressure, high thermal efficiency, save 50% steam or above than continuous foaming machine

3.Adopt high-precision imported pneumatic control valve so that temperature can be controlled at ±1%, EPS grains are at same level with low water content.

4.Correct feeding method can assure even density
