Ferrous Castings - Mould, Core, Pattern Materials and Processes

Abstract

Any amount of care in melting and pouring of metals and alloys cannot help in producing good quality castings if no proper attention is paid in preparation of moulds and cores. In fact, mould and core production may account for one-third of the cost of finished castings. No economy measure is complete without proper selection of moulding materials and maintaining their specification through control tests. Choice of the right type of raw materials for preparation of moulds and cores and specification control ensure a mould or core of uniform quality and minimises the number of defective castings, and this is considered as an important aspect in productivity.
