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.
