Sand Castings
FERESPE, founded in 1981, focuses on the production of technical parts for high performance applications, using the following alloys:
– Duplex, super duplex and super austenitic stainless steel
– Medium and low alloyed steel
– High alloyed cast iron
Exports about 90% of its production to several different industrial sectors and positions itself in a small and medium series niche market.
Sand Castings uses a silica-based material to create a moulding surface. After achieving the required chemical composition, the molten metal is poured into a mould which has the desired shape cavity to cool down and solidify .
Main Characteristics of Sand Casting:
- Larger castings
- Good Dimensional Accuracy
- Good Roughness Quality
- Complex shape and near net shape design, if compared with forging or metal worked pieces
