Hot mould cleaning without abrasion.

Eliminate moulding gases and additive deposits without removing the die and without scratching polished surfaces. Maintain the highest aesthetic quality from first to last shot.

Hot and mounted mould cleaning to eliminate production stoppages and guarantee parts free of aesthetic defects.

Dryce systems allow direct in-machine intervention using thermal shock to free vents and complex textures. This method eliminates the need for disassembly, prevents halos or gas burns and maximises line productivity.

Wear of polished surfaces

The build-up of moulding gases is inevitable, but removing it with brushes or abrasives ruins the surface finish of the dies. This forces frequent and costly manual re-polishing operations that alter mould tolerances and increase rejects.

For a production manager, the cost of cooling and heating the press for cleaning is an enormous economic burden on OEE (Overall Equipment Effectiveness).

Thermal Shock and Targeted Sublimation

Dryce intervenes with a non-abrasive mechanical force: dry ice. Striking the dirt on the hot mould, the thermal shock detaches it instantly, while the ice sublimates without leaving traces.

This technology preserves mirror-finish surfaces and the most delicate photo-engravings, instantly freeing vent channels. It allows production to resume immediately, guaranteeing parts that conform to the highest aesthetic standards.

Questions about the CryoBlasting solution
Does it scratch mirror-polished surfaces?
Absolutely not — dry ice is softer than steel and sublimates without scratching or rounding off corners.
Does it remove PVC or Rubber residues?
Yes, it is extremely effective at crystallising and removing tenacious and corrosive polymer residues.
How long does it take to clean a mould in a press?
On average 5 to 15 minutes, depending on the complexity of the geometry.
