zhejiang huasheng eps pre-expander machine with high efficiency

huasheng machinery has severl types of pre-expander machine, including lost foam pre-expander, Continuous Pre-expander Machine, batch type pre-expander machine and so on.

EPS Pre Expander Machine belongs to batch type, but compared with normal EPS Batch Pre-Expander Machine, it updates, less tolerance, high capacity and nice appearance.

Here are some pictures of the new expander.

how does it work?

An EPS pre-expander machine is a piece of equipment used to expand raw polystyrene beads into larger, lightweight EPS foam beads. This process is called pre-expansion and involves heating the polystyrene beads with steam to a specific temperature and pressure, causing them to expand and release their pent-up gas.

During pre-expansion, the EPS pre-expander machine uses a series of valves and other components to control the temperature, pressure, and steam flow to the polystyrene beads. By carefully controlling these factors, the machine can produce expanded beads of the desired size and density.

Once the pre-expanded beads have been produced, they are then transferred to a moulding machine where they are fused together using heat and pressure to create a finished EPS foam product.
