Feeding System: Automatically feeds raw polystyrene beads into the pre-expander.
Heating System: Uses steam or hot air to heat the beads, causing them to expand. This is a critical step that facilitates the expansion process.
Expansion Chamber: The main body where the beads are heated and expanded. The chamber is designed to maintain the right pressure and temperature levels for effective expansion.
Cooling System: After expansion, the beads need to cool down to ensure they retain their expanded shape.
Control Panel: Automated controls regulate the temperature, pressure, and timing of the expansion process for precision and efficiency.
The expanded EPS beads produced by the pre-expander can be used in a variety of applications, including:
