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

The Batch Type EPS Pre-expander from Shijiazhuang Haosen Business Service Co., Ltd. is a dedicated machine for expanding polystyrene beads into lightweight EPS foam, a core material in packaging and insulation. This model is built with a user-friendly interface for monitoring the expansion process, ensuring consistent output quality for high-volume production. Its energy-efficient design reduces power consumption while maintaining performance, and the durable construction minimises maintenance downtime in industrial settings.

Expanded polystyrene produced by this equipment typically achieves a bulk density range of 12 to 30 kg/m³, depending on the bead grade and expansion ratio. The machine handles standard EPS bead sizes from 0.5 mm to 3 mm, with typical expansion ratios between 30:1 and 50:1 for common applications. Industry-standard steam pressures of 0.4 to 0.6 MPa are used for the pre-expansion phase, with residence times adjusted to the target density. The resulting foam is used in protective packaging, construction insulation panels, and decorative mouldings.

This pre-expander serves manufacturers of EPS blocks, sheets, and custom shapes for sectors such as electronics packaging, cold chain logistics, and building construction. Buyers commonly source this equipment for in-house foam production to reduce material costs and gain control over quality. Trade terms such as FOB or CIF are typical for this category, with packaging designed to protect the machine during transit. Confirm the exact capacity, steam requirements, and output specifications with the supplier before ordering.
