When can die casting offer advantages over screw machining?
A. Automatic screw machining entails the lowest tooling cost of any production method. Highly automated screw machines are not labor intensive. The process, which uses bar stock as raw material, offers very poor material utilization, however, sometimes less than 50%. The choice versus die casting will usually depend on production quantities, with the die casting advantage increasing as production rates increase. Unusually complex design shapes are routinely produced as die castings, while they would be costly or impossible as machined parts.
