Evaluation of casting drawing in accordance with achievable investment casting tolerance.
Die manufacturing : A negative replica of the component os prepared in the form of metallic die.
Diaposable wax pattern is produced by injecting wax from PLC controlled horizontal wax injection machines in the semi automatic, water circulated die tool
Produced wax pattern from single or multicavity die tool are then assembled to form a tree structure having feeding , gate , runners & sprue.
Sucessive coasts of ceramic slirrues & refactory sand are applied with intermediate drying time to form a shell.
Wax pattern invested in "shell" is melted out by applying heat source during de-waxing stage to form a hollow shell.
The specified molten metal is poured in the hot bacjed hollow shell.
Upon cooling the resulting precision castings are achieved agter usual operaion & gate removal, cleaning & subjected to further processing such as heat treatment, surface treatment etc.
