Development of Investment Castings Drg. (I.C. Drg.) On receipt of the machining drg. which is scrutinized & vetted and IC Drg. is prepared with the help of CAD/CAM facilities.
Die Design & Drg.: On the basis of IC drg., Die Design Drg. is prepared by CAD/CAM facilities keeping in view positions of parting line, Injection Point & Gate Position. Multi-cavity Die are designed in CAD Software depending on requirements.
Selection of Die Material: Depending on No. of Cavities, Complexity of Die, Production life of Die, Dimensional stability etc. Die material is selected.
Development of Die: Proper care is taken while development of die like:
Dowels Pins should be hardened, ground, slide fitting in the bush.
Mismatch of parting line.
Proper machining & matching of internal all fittings without pins/burrs.
Die block faces to be ground finish, perpendicularity (90°) for reference measurement.
Cavity of Dies be well-polished without dents, scratches or extra metal match.
Dimensional Check/Inspection of Dies: Inspection both visually and dimensionally are carried out before wax pattern injection and wax patterns after injection.
