This operation consists in separating the surrounding flash from the article. Normally this is carried out by cryogenic machines. Articles with big dimensions and critical angles are deflashed by hand.

The cryogenic deflashing permits the separation through reciprocal impacts of the articles at very low temperatures obtained by the expansion of liquid nitrogen (-80°C -150°C) into rotating containers.

Sometimes this separation is supported by the use of steel spheres, which shorten the process.

Macchinari Utilizzati

The production cycle of our products is completely executed inside our facility. In our group we have at our disposal: more than 60  horizontal and  vertical injection machines plus  compression machines. Besides we have numerous machineries for the deflashing, for the finishing, for the post vulcanisation and for the final controls.
