Import Eps Batch Pre-Expander — Buy in Bulk from Supplier in China

The EPS Batch Pre-expander from Herooo Machine is a stationary industrial unit designed for batch-wise expansion of polystyrene beads using steam under controlled pressure and temperature. The unit operates with a single chamber capacity of 1.5 cubic meters and includes a steam injection system with manual valve control and a discharge gate for batch release. It is built with 304 stainless steel inner lining and carbon steel outer casing, as confirmed by the supplier's technical notes.

Typical bead expansion ratios range from 20 to 50 times the original volume, depending on steam pressure and dwell time. The machine supports standard EPS bead sizes between 0.3 and 0.8 mm, and operates at steam pressures of 0.2 to 0.4 MPa, which aligns with industry norms for batch pre-expansion. Cooling cycles are manually timed, and the unit does not include automated drying or conditioning stages, requiring downstream equipment for full production flow.

This pre-expander is commonly purchased by small to mid-sized EPS packaging and insulation manufacturers in Southeast Asia and Eastern Europe seeking cost-effective batch processing. Buyers typically require delivery within 45 to 60 days and prefer FOB Shanghai or CIF terms. The machine is shipped disassembled in a standard 40-foot container, with toolkits and basic manuals included. No electrical certification is listed, so buyers must verify local compliance before installation.
