Expanded Polystyrene Moulding

The protective packaging, components in air conditioners, insulation structures and insulated concrete for building systems are made using expanded polystyrene moulding.

These products are mainly used in the consumer electronics and electrical, air conditioning and housing industries.

To make an expanded polystyrene moulding product, first the raw material is pre-expanded using superheated steam in a batch pre-expander to the required expansion ratio before it is conditioned in the silos for aging. The aged pre-expanded material is next fed into a moulding machine with a dedicated tooling where steam is used to expand the material within the mould cavities into the desired shape. Finally the parts are dried in ovens before they are inspected and packed for delivery.
