New standards set for mould cleaning using ASCO technology

0

In cooperation with Hüttenes-Albertus, a leading manufacturer of chemical products, ASCO Carbon Dioxide’s dry ice blasting technology is setting new standards for the removal of coatings on moulds.

Mould and tool cleaning has great importance in foundry operations. This is especially true when it comes to requiring optimal cleaning results of moulds and core boxes since an efficient cleaning process does not only increase quality but also boost productivity while optimising costs.

In open dialogues with foundries, both companies figured out that there is still no efficient overall solution for partial or complete removal of the coating of moulds. Currently, heavy metal casting foundries need to remove the mould´s finishing coating several times a day. In addition, a regular removal of the base coating and an occasional roughening of moulds, is required. The last point there is an important criterion for the adhesion of the coating.

The removal of the finishing coating is mostly unproblematic and can be done efficiently with pure dry ice blasting which is a common practice in the foundry industry. However, when it comes to the removal of the base coating or the roughening process, pure dry ice blasting is of limited suitability, as the procedure takes too long or the desired effect cannot be reached due to physical reasons.
