Liquid wax injected into a molding die having the desired shape Of final product for making wax pattern.

The wax pattern are allied with gate,runner,pouring cup and sturts according to the size and the shape of the pattern.

ceramic coating applied in the wax pattern assembly,the most importnt stage of the coating process is primary coating,where a very find grade of the sand is used to casting with excellant surface finish.

Wax pattern assembly with number of coatings converted into shell after de-waxing, wax inside the solid ceramic coating being removed in liquid from with applying pressurized steam, steam pressure and cycle time are very critical parameters to be controlled during the de-waxing.

The shells are preheated to remove moistur e content and residual wax from the shell and to sinter the ceramic of shell. The specified grade melted in induction furnace is poured into pre-heated shells and shells are left for solidification.V.

The ceramic shell is broken off by vibrating knockout machine and individual casting are cut away by arc welding or gas cut off method.

Heat treatment for improving mechanical properties and to get proper microstructure results. We have batch type furnace with rapid quenching facility, Furnace is calibrated according to API 6D and there is systemized control for real time temperature of different zones..

We do fettling for removing of excess in gates and to finish final product with Abrasive grinding and final surface finish with greet shot blasting, Electropolishing or as per customers requirement.

Inspection is the most important part of engineering process. We do inspection of each batch with respective drawing, requi red instruments and gauges to insurecustomer requirements.

Final products are packed in wooden box or as per requirements of customers. We apply rust preventive oil casting of carbonsteel to avoid rust..
