How Does the Machine Work?

The operation of an EPS Shape Moulding Machine can be broken down into a few key steps:

A. Pre-expansion: The raw polystyrene beads are first subjected to steam in a pre-expander, causing them to expand and become porous.

B. Filling the Mould: The expanded beads are then transferred into the mould of the machine, filling it uniformly.

C. Steam Application: The mould is closed and subjected to steam. This causes the beads to expand further and fuse together, taking the shape of the mould.

D. Cooling: After the steaming process, the moulded EPS needs to be cooled. This is achieved by circulating cold water or air around the mould.

E. Ejection: Once the cooling phase is completed, the moulded EPS shape is ejected from the machine and is ready for the next stages of processing or packaging.
