EPS (Expanded Polystyrene) shape moulding machine is a type of equipment used in the manufacturing process of EPS foam products.
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.
Pre-expansion: The process begins with the pre-expansion of EPS beads.
Aging: The expanded beads are then transferred to an aging silo, where they are allowed to cool and stabilize for a certain period.
Molding: The aged beads are then fed into the shape moulding machine.
Steam and pressure application: Once the mold is filled with the expanded beads, steam is injected into the mold cavity. The steam causes the beads to further expand and fuse together, conforming to the shape of the mold. Simultaneously, controlled pressure is applied to ensure proper density and dimensional stability of the final product.
Cooling and demolding: After the desired molding time, the steam supply is stopped, and the mold is cooled using either water or air. The cooling process solidifies the expanded beads into a solid foam shape.
EPS shape moulding machines are available in different sizes and configurations to accommodate various production capacities and product requirements. They can be operated manually or automatically, depending on the complexity and level of automation.
These machines offer several advantages, including high production efficiency, precise molding control, energy efficiency, and the ability to produce lightweight and durable EPS foam products with excellent thermal insulation properties.
