Investment casting processing

Steel properties include tensile strength, elastic modulus, plasticity, impact toughness, cold brittleness, hardness, cold bending properties, weldability, heat treatment, cold working and aging. So many container hinges are make by steel. And use the process is Investment casting. 

Steel casting parts often have various casting defects such as blisters, pores, cracks, shrinkage porosity, shrinkage cavities and inclusions, and production control is difficult, especially for sand-cast alloy steel castings.The melting point of cast steel is high, the molten steel is easy to oxidize, the fluidity of molten steel is poor, and the shrinkage is large. The volume shrinkage rate is 10-14%, and the linear shrinkage rate is 1.8-2.5%. In order to prevent defects such as undercasting, cold shut, shrinkage cavity and shrinkage porosity, cracks and sand sticking in Investment Casting Hinges , more complicated technological measures must be taken.
