EPS color steel sandwich board is kind of thermal insulation sandwich board which is made of color coated steel plate as surface layer, self-extinguishing foam as sandwich material and combined with specific production process. The core materials are divide into polyurethane and polystyrene foam. Either kind of sandwich board has the “three-in-one” working characteristics.

Expandable polystyrene (EPS) is the raw material used in the Plastic production process, it becomes over in blocks or castings afte three stages of production, namely the pre-expansion process, which make the beads compact of the raw material convert into cellular plastic beads with small closed cells, EPS blocking process, which make EPS foam beads to become big foam board through steam heating and wind cooling, and EPS cutting process, which cut the complete block of the EPS product into different sizes and shapes through the cutting line.
As mentioned above, the working principle of EPS pre-expander machine is to expand a fixed amount of raw materials to a fixed volume to achieve the required density. It sounds pretty easy but actually, there are multiple steps of the working process, so there is a need to know how to operate it well.
Tecnodinamica pre-expanders are fully automatic machines for expanding EPS. Pre-expanders guarantee superior performance over time and maximum quality in the EPS processing phase in terms of: Efficiency: constant quality and repetitiveness of the material with reduced cycle times. Minimum residual humidity in the expanded material. Broad range of densities available.
