About EPS Batch Pre-expander Machine

The EPS Batch Pre-expander Machine is a new product on the market that is designed to pre-expand EPS foam blocks before molding. The machine uses steam to heat the EPS foam and then expel the air from the cells, which makes the foam blocks easier to mold. This machine is ideal for companies that produce large quantities of EPS foam products, as it can significantly reduce production time and costs.

Main advantage:

1. Fully automatic and continuous production.

2. Controlled by touch screen and PLC, easy to operate.,

3. High output and save energy.

4. Exact density of foam beads

5. Stable quality and less failure.

Specification:

1. This machine applies PLC and touch screen, automatic feeding, electronic weighing, temperature control, material level control to realize automatic and continuous production.

2. Electronic weighing system and material level control system ensure the density of the foamed beads, which make the beads uniform and keep the density tolerance within 2%.

3. Japan original pressure reducing valve controls the steam pressure of the chamber, which ensures the outcome pressure of the valve constant and the inner temperature stable, which keeps the foamed material equal and prevents the beads agglomerate because of the bad temperature control.

4. Automatic material charging system improves efficiency and reduces labor intensity.

5. The closed constant pressure foaming barrel has high heating efficiency. It can save more than 50% energy compared to the continuous pre-expander.

6. Automatic discharging from the pre-expander, which can automatically filter and crush the ball material and transport the foamed material to silos.

7. Most of the main components are world-famous brand, with reliable performance, stable quality, long service life and low maintenance cost. 

Note:

*Korean vibration sensor is optional

*Proportional valves of steam and compressed air are optional
