EPS batch pre‑expander machine (also called batch‑type EPS pre‑foaming machine or intermittent pre‑expander) is a core piece of equipment in the expanded polystyrene (EPS) production line. It processes raw EPS beads in fixed batches to expand their volume via controlled heating and pressure, producing uniform, low‑density pre‑expanded beads for molding.
