Auto Lost Foam EPS Polystyrene Foam Batch Pre-expander Machine For Beads Foaming

This pre-expander machine is designed for the foam production of beads. The machine consists of a cylindrical chamber with a small inlet and outlet, that is rotated at a high speed. The pressure produced by the rotating chamber squeezes the air out of the foam, resulting in an expanded foam. This machine is perfect for producing small batches of beads.

About EPS Batch Pre-expander with Second Expansion Machine

The EPS Batch Pre-expander is a device that can be used to increase the output of an EPS production line. It works by compressing the EPS foam so that more foam can be produced in a shorter time frame. This can be especially helpful for companies that produce a high volume of EPS foam. The pre-expander can also help to improve the quality of the foam by removing any air pockets or other inconsistencies.

A typical EPS production line includes an extruder, a die, and a series of cooling tanks. The throughput of the line is limited by the size of the die. EPS Batch Pre-expander with Second Expansion Machine increases throughput by increasing the size of EPS pellets exiting the die.

Specification:

1. Steam system: accurate pressure reducer to keep stable and accurate steam, ensure material variation;

2. Pressure control: Pressure sensor with muli-steam exhausting system to keep expansion chamber pressure stable, Also reduce the steam consumption;

3. Temperature control: Adopts temperature sensor to keep accurate expansion temperature, which is suitable for high density expansion, less broken beads;

4.adopts PLC and Touch screen, electronic parts, valves are famous brand, which make the whole working procedure automatically and stable
