EPS Continuous Pre-Expander Machine Dongshan Plastic Machinery

The EPS continuous pre-foaming machine independently developed by Dongfeng Plastic Machinery is specially designed for high-efficiency foam production.

The equipment uses advanced steam heating and vacuum control technology to achieve uniform expansion and stable production of EPS particles, ensuring excellent quality of foam particles.

The whole machine has compact structure, easy operation, energy saving and environmental protection, and is suitable for large-scale EPS foam packaging, mold filling and the production of various foam products.

Dongshan Plastic Machinery Continuous Pre-foaming Machine not only improves production efficiency, but also significantly reduces labor costs. It is an ideal high-performance equipment choice for modern EPS production companies.

Products Detail

Control System

Instrument control cabinet, automatic operation, convenient maintenance.

Structure Design

Stainless steel and insulation measures
Set steam pressure reducing valve by user’s option.

Processes

Primary feed device and secondary feed device
The EPS beads are fed into the fluidized drying bed (optional) by the feeding, foaming, and then enter the curing silo through the fan conveying device to complete the foaming process of the raw material. The above process can be circulated.

Production Efficiency

Stable quality and high production efficiency
Relatively uniform production density for 7-35kg/ m³
