MAINPOL's EPS ball factory is specifically designed for the production of EPS balls for different applications such as puff filling, or other elements, as well as for the manufacture of lightweight concrete.
This installation is very easy to use and requires a very small space, as well as very few personnel and a low energy cost.


The EPS manufacturing process does not emit polluting gases into the atmosphere



The Pre-expander transforms the expandable EPS (raw material) into expanded EPS, achieving the necessary density depending on the production needs. It is an easy-to-use machine and a fully automated process.


The steam boiler produces the water vapor necessary for the different phases of the expansion process (expansion of the raw material beads, welding and pressing of the block) It is fully automatic and requires minimal maintenance.


The silos are used for the storage and rest of the expanded beads, while their stabilization occurs. The dimensions of the silos are very varied and adaptable to customer needs.


The compressor produces the air necessary for the movement of valves, flaps, etc. The tank is a storage of the air produced by the compressor.
