MAINPOL's moulding factory is specifically designed for companies with consumption of EPS parts such as: polystyrene boxes, motorcycle helmets, packaging elements, etc. so that they can produce their own products at a low cost. Some of the advantages of this type of factory are that no previous experience is required, it has a low energy and personnel cost, in a reduced space.


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 Moulding Machine is a machine designed for the production of EPS figures from moulds such as polystyrene boxes, motorcycle helmets, packaging parts, etc.


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


  • Necessary covered area: 225 m2. If the silos are exterior 150 m2.
  • Molding plate size: 1000 x 800.
  • Production: 1 cycle / 45 sec. according to piece.
  • Necessary personnel: 1 operator.
  • Steam consumption: 400 kg/h.
  • Fuel consumption: 35 l/h.
  • Electric consumption: 15 KWh.
