This particular process is widely used for the production of a large number of polyurethane or plastic articles (including gaskets, household products …). Generally, these items are shaped, by compression into iron steel moulds, and sometimes very heavy and of different dimensions.

The maintenance of these industrial moulds is of great importance to prevent the damaging of entire production lots.

In this specific case, the contaminants to get rid off are resulting from the production process:

  • release agents are used at each operation to avoid adherence of melt raw materials to the moulds. Their repeated use, combined with temperature variations on mould surface lead to the forming of a thick layer of release chemical residues;

  • during compression operations, dark fumes from melt raw materials are expelled from the moulds. After several production lots, a layer of exhaust fumes covers the surface of the moulds;

  • and, of course, after some time, polyurethane or plastics residues accumulate on the internal surface of moulds.

The modularity of BICARjet® surface cleaning equipments offers a wide range of suitable and valuable combinations, as for instance:

  • a SOBIJET® MJ1000  work cabinet, associated with a SOBIJET® 224E delivery unit, with an electronic control panel is a able to process moulds measuring maximum 850 x 850 mm and weighing not more than 150 Kg.

  • a SOBIJET® MK1000  or MK2000 work cabinet, with a loading capacity up to 1000kg is the right solution for heavier moulds.

  • for heavier moulds, the loading capacity can be increased up to 3000 kg,  and an external turntable, sliding on rails, with or without power aid makes loading operations easier for the operator.

  • the SOBIJET® MJCOMP  is a very competitive compact cleaning system.

All SOBIJET® cleaning machines are equipped with a water jet pistol for high efficiency results. It is also possible to work with a dry jet only. In this precise case, only the physical action of MELTRON® is exploited, but not the chemical and degreasing ones.
