Technology & Equipment


The mould deterioration may appear at aluminum shaped casting.

Multiple cracks at the mould surface spoil the moulding surface and make difficulties for process.

The right mould at the picture had the same cracks as the left one. The cracks were cured by K714 powder and mould continued operation.

After 1000 castings the repaired mould continues to be good for the casting process.

  At restoration cracks are blasted by abrasive K-00-04-16. Powder K714 is sprayed to the prepared surface at temperature setting 4. The excess of coating material is milled (the coating material is rather soft without the annealing). The mould is annealed 1 hour at 800 . After the cooling the mould is ready to use. *AS*
