Hand moulding

Single pieces and small series with casting weight from 100 to 10000 kg made in furan moulds or masses with bentonite in hand or partially mechanized moulding.

Machine moulding

Small, medium and large series with casting weight up to 750 kg, produced on automatic moulding lines with vertical and horizontal mould division.

Lost wax moulding method

Precision castings using the lost wax method, which allows to achieve very high dimensional accuracy for very responsible castings with small details.
