Electric Motors & Pumps Industry
In our plant, we manufacture all kinds of pump spares, like casting Impellers, bowls, and diffusers for horizontal and vertical pumps, submersible pumps, self-priming mini pumps, and vacuum pumps. We also manufacture motor spares such as front and rear bearing housings, air cooling fans, upper housings, and lower housings for all types of motors.

Refrigeration & Food Process Industry
The motors that are produced in our plant are used in ice cream, dairy plants, food processing machine parts, clamps, ferrules, and 2- and 3-way valve bodies for the refrigeration industry. We produce all kinds of ball valves, gate valves, solenoid valves, and all types of fittings like tees, elbows, sockets, and couplings.

Automobile Industry
The products and spare parts of the pre-combustion chamber for tractors, matadors, and Tata Sumo, the gear shifter for 4 wheelers, the water pump body, timing belt pulleys, and 2 wheeler spares are also manufactured in our plant.
Fire Fighting Equipment
We produce various types of equipment used in firefighting, such as couplings, clams, knurling bush, hydrant valves, sprinklers, male-female couplings, nozzles, etc.

General Engineering Industry
In our plant, we manufacture various types of gears, chain links, sewing machine parts, electrical conductor parts, and spares for textile, aerospace, and Orthopaedics and all general industries require a high degree of as-cast finish with complicated design.

Salient Features :-
Components weighing from 10 grams to 35 kg can easily be cast. High accuracy of complex shapes and designs with obsolete reproduction of fine holes and slots can be cast by his process. Through this process, products that are essentially near-net shapes are totally eliminated or reduced to the minimum possible.
Material used for Investment Casting :-
At our plant, we use all types of ferrous materials, including carbon steel, stainless steel, steel alloys, aluminium, and copper-based alloys, in accordance with the ASTM and ISI standards.
Manufacturing Process :-
Die Making :-
Investment casting dies are specially made from aluminium or Hard Die steel with a single or multiple cavities to produce wax replicas of the required Components.
Wax Replicas :-
Wax replicas are made by this process by injecting the molten wax into the single or multi-cavity dies.
Pattern Tree :-
The individual wax replicas, assembled to form a single mould, look like a patent tree or cluster.
Shell Making :-
The pattern tree or cluster is repeatedly dipped in a liquid binder or ceramic power several times with time intervals for curing to form a shell mould with a thickness of 5 to 12 mm, depending upon the shape and size of the components being produced.
De Waxing of Shells :-
In this process, the wax is melted out of the shells, leaving hollow ceramic shells.
Shall Baking :-
Before casting, the hollow shells are well-backed in a shell baking furnace so as to stand high temperatures or high pressure during the casting process.
Casting :-
The molten metal from the induction furnace is poured into the shells to make castings in the form of trees or clusters with several similar components. Knock-out, Cutting, and Finishing: Casted shells are then knocked out with pneumatic hammers and cut into individual components by a cut-off machine, followed by final finishing by air grinding or shot blasting to get the final "AS CAST". Our plant has the capacity to draw 3 tonnes of casting per day.
