WIWOX® Extruder screws Pyrolysis oven

Thermal decoating of extruder screws

Product description

Thermal cleaning at up to 500° C removes all organic residues, even from fine bores. Depending on the melting and decomposition point of the residues, they are either melted or pyrolysed. The resulting exhaust air during the carbonization phase is burned in the afterburner chamber at over 850° C. The exhaust air is then burned in the afterburner chamber at over 850° C. The exhaust air is then burned in the afterburner chamber.

Cleaning in the pyrolysis process requires subsequent post-cleaning. Inorganic components, oxidation residues, corrosion, etc. remain on the tool surface and must be removed. The ultrasonic process with acidic or alkaline cleaning media or the blasting process with organic and mineral abrasives are suitable for this purpose.
