Set the benchmark in the industry with DongShen’s state-of-the-art Polystyrene Preexpander Foam Block Making Machine. This innovative device is specifically engineered to manufacture Expanded Polystyrene (EPS) blocks. These blocks have a multitude of applications, ranging from providing insulation for houses to serving as protective packing material for a range of products. The Polystyrene Preexpander is designed with a forward-thinking approach to promote efficiency and reliability. Its primary function is to transform raw EPS materials into high-quality foam blocks. These blocks can subsequently be cut into sheets, suitable for various applications. One of the prime applications of the sheets produced by our Polystyrene Preexpander is house insulation. In the face of extreme weather conditions, maintaining a comfortable indoor environment can be challenging. That's where our EPS blocks come into play. They provide exceptional insulation, helping to maintain a steady indoor temperature regardless of the weather outside.

Product Details

Expanded polystyrene foam block making machine is used to make EPS blocks, then cut to sheets for house insulation or packing. Popular products made from EPS sheets are EPS sandwich panels, 3D panels, inner and outer wall insulation panels, glass packing, furniture packing etc.

Expanded polystyrene foam block making machine is suitable for small capacity request and low density blocks production, it’s economic EPS machine. With special technology, our expanded polystyrene foam block making machine can make 4g/l density blocks, block is straight and of good quality.

Machine completes with main body, control box, blower, weighing system etc. 

Main Features

1. The machine adopts Mitsubishi PLC and Winview touch screen for automatic mould opening, mould closing, material filling, steaming, temperature keeping, air cooling, demoulding and ejecting.
2. Machine’s all six panels are through heat treatment to release welding stress, so that panels cannot deform under high temperature;
3. Mould cavity is made of special aluminum alloy plate with high-efficiency heat conduction, aluminum plate thickness 5mm, with Teflon coating for easy demoulding.
4. The machine set up high-pressure blower for suction material. Cooling is done by convection air by blower.
5. Machine plates are from high-quality steel profile, through heat treatment, strong and no deformation.
6. Ejection is controlled by hydraulic pump, so all ejectors push and return at same speed;
