Hand moulding
Single pieces and small series 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 weight up to 250 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.
