Pre-expander:
- This component is responsible for expanding raw polystyrene beads using steam and heat. The pre-expander transforms the beads into lightweight foam that can be molded into blocks.
Block Molding Machine:
- The expanded EPS beads are transferred to the block molding machine, where they are formed into blocks using molds. The machine applies heat and pressure to fuse the beads together.
Steam Chamber:
- A steam chamber is used to evenly distribute steam during the molding process, ensuring proper expansion and bonding of the beads to create solid blocks.
Cooling System:
- After the molding process, a cooling system is employed to help solidify the blocks and maintain their shape.
Control Panel:
- Modern EPS block molding machines come with an advanced control panel that allows operators to monitor and adjust the temperature, pressure, and timing for optimal production quality.

Feeding:
- Raw polystyrene beads are loaded into the pre-expander for initial expansion.
Pre-expansion:
- The beads are heated with steam to expand them to several times their original size, creating a lightweight foam.
Transfer:
- The expanded beads are transferred to the block molding machine, where they are positioned in molds.
Molding:
- The molds are heated with steam and pressure is applied to fuse the beads together. This process forms solid EPS blocks.
Cooling:
- The molded blocks are cooled to solidify and enhance their structural integrity.
Ejection and Cutting:
- After cooling, the formed blocks are ejected from the molds and may be cut to specific sizes as per requirements.

Insulation: Used in building and construction for wall, roof, and floor insulation due to its excellent thermal properties.
Packaging: Used for protective packaging of fragile goods, such as electronics, machinery, and glass products.
Marine Applications: Often used for buoys and floats due to its buoyancy and lightweight nature.
Craft and Decorative Items: EPS blocks can be used for crafts, model making, and decorative pieces.

High Efficiency: Capable of producing large quantities of EPS blocks in a relatively short time.
Cost-Effective: Produces lightweight blocks that reduce shipping costs and improve handling.
Customization: Blocks can be molded into various sizes and shapes to meet specific customer needs.
Environmental Considerations: EPS can be recycled, contributing to sustainable manufacturing practices.
