摘要

Squeeze casting is a special casting technique which combines the advantages of traditional high pressure die casting, gravity permanent mould casting and forging. It is a relatively new and developing casting process. It is otherwise called as squeeze forming, liquid forging, liquid pressing, extrusion casting, liquid metal stamping, pressure crystallisation and corthias casting. The above-mentioned process was discovered by the Russians and later it was developed in countries like USA, Europe and Japan/This casting process is applied for processing of both ferrous and non-ferrous materials besides composites. The major advantages of this technology are elimination of porosity and sariakage, one hundred per cent casting yield, attainment of greater part details, good surface finish, good dimensional accuracy, high strength-to-weight ratio, improved wear resistance, high corrosion resistance higher hardness, resistance to high temperature, improved fatigue and better creep strength. The components, manufactured by this casting method, requires lesser post-machining operation and they have improved mechanical properties like higher strength and ductility.
