Gibson Centri Tech produces two types of mould coating specifically designed for centrifugal casting applications to assist traction on the coated surface allowing even flow of metal during the casting process, control cooling rates and enabling ease of extraction of the casting.

Systematic mould preparation will provide long-term scrap reduction benefit. For the best results the mould surface must be completely free from dust traces from the previous cast. Failure to completely clean the whole mould surface runs the risk of coating spalling for the next cast, resulting in sticking or defective casting surfaces. The mould should be pre-heated to correct temperature to aid adhesion.
