Vacuum type EPS pre-expander

Products Details：

Vacuum type EPS pre-expander is an advanced machine that uses steam and a vacuum system to heat and expand raw polystyrene (EPS) beads, creating lightweight foam particles for insulation and packaging, with the vacuum rapidly cooling and drying beads for better density control, faster processing, and lower energy use compared to traditional methods. These automated systems feature PLC controls, precise temperature/pressure regulation (PID), automatic feeding, and self-adjusting weighing, ensuring uniform, high-quality foam with consistent density and reduced water content.
