EPS (Expanded Polystyrene) shape moulding machine is a type of equipment used in the manufacturing process of EPS foam products. EPS foam, also known as Styrofoam, is a lightweight and versatile material widely used for insulation, packaging, and construction applications.
The shape moulding machine is specifically designed to produce various shapes and sizes of EPS foam products, such as blocks, sheets, panels, and custom molded products. It uses steam and pressure to expand and mold the EPS beads into the desired shape.
Here's a general overview of how an EPS shape moulding machine works:
Pre-expansion: The process begins with the pre-expansion of EPS beads. The beads are fed into a pre-expander, where they are exposed to steam and heat. The heat causes the beads to expand and fuse together, forming expanded beads with low density.
Aging: The expanded beads are then transferred to an aging silo, where they are allowed to cool and stabilize for a certain period. This aging process helps to improve the performance and consistency of the EPS foam.
Molding: The aged beads are then fed into the shape moulding machine. The machine consists of a mold cavity in the desired shape and size of the finished product. The beads are evenly distributed within the mold cavity.
