In this department the moulding process (through injection) of the different types of polyurethane takes place.
Polyurethane is a thermosetting polymer, obtained principally from a mix of two components: Polyol and Isocyanate.
The mix is injected by means of foaming machines into a mould to get a pre-shaped piece, either finished or ready to be upholstered.
According to the selected formula, with specific parameters like ratio between Polyol and Isocyanate and processing conditions many types of foams can be obtained, which are different for density, hardness, fire retardant classification, use (see POLYURETHANES).
We primarily produce unfinished polyurethanes (raw foams), ready to be upholstered with leather or fabric, and finished polyurethanes which are ready to sell.

The department is equipped with 10 moulding carrousels, one or more for each type of PU. Each carrousel employs one or more high pressure foaming machines. All manufacturing parameters are computer controlled, especially weight, pouring ratio, temperature and pressure. Detaching chemicals and coloured paints for finished polyurethanes are sprayed on the mould's surface by means of robots that also manage the movement of the pouring heads of the foaming machines.
