Solidworks, Autocad	Solidworks, Casting simulation (Outsourced)	100+ Nos	2000 Sq.ft

Moulding

We have a dedicated team and complete facilities for hand moulding for Sodium Silicate Co2 process and Alpha Set Process for moulding and chemically bonded sand processes for core making.

Melting Foundry

Induction furnaces 150kgs, 300Kgs crucibles

Centrifugal Furnace: We can produce horizontal centrifugal castings with O.D. up to 300mm, length up to 100 mm, and weight up to 250 kgs.

We have extensive manufacturing and testing facilities to produce 286 MT per annum and of one-off castings or high repetition castings (in multiples of 100s) with optimal lead times. The melting process is carried out in a medium frequency induction melting furnace.

Melting

Our furnaces are capable of heat treating carbon steel, low alloy steel, martensitic steel, austenitic stainless steel, precipitation stainless steel, duplex stainless steel, and nickel- based alloy castings.

Knockout

The Knock out process involves the separation of castings from sand molds, sand from mould boxes and cores from castings. Operators are well-trained in the implementation of the process.

Fettling Shop

The fettling shop consists of hand grinders and heavy swing frame grinders along with Shot Blasting, Acid Pickling and Passivation facilities.
