CASTINGS

S.G Iron and Grey Iron--We have a network of quality manufacturers in this area. Please download the file for a sample of the castings that we can provide.

Stainless steel castings--Stainless steel castings are in demand and it is very hard to find quality suppliers who are not overloaded. For the benefit of our clients we have an understanding with suppliers in india so that priority is given to our work.

Investment castings--The plant capacity is 144 tons/annum for producing Investment Castings and with a few changes the capacity can be doubled.

We provide manufacturing of Precision Investment Castings in various steel alloys like Stainless Steels, Carbon Steels, Heat Resistant Steels, as well as in copper based alloys like Gunmetal and Phosphor Bronzes. Weights range from 5 grammes to 8 kgs per piece. We have extensive and modern machinery for producing Investment Castings and the list is given below:

Inspection Methods: Dial callipers, height gage, spectrometric chemical analysis & ultrasonic flaw detection are in-house. We source our radiographic, magnetic particle testing and dye penetrant tests requirements from a neighboring, BARC approved NDT level 2 certified agency

Heat treatment: A professional and excellent heat treatment shop does heat treatment of our castings and provides necessary reports of each batch. Solution annealing of stainless steels and normalizing of carbon steels is done completely in-house.

Chemical analysis of incoming scrap and out going castings is done on day-to-day basis on our in-house, state-of-the-art optical emission spectrometer.

Tooling: Wax injection tooling is manufactured both in-house and with experienced pattern makers by CNC-VMC machining, wire cut and spark erosion methods.

Quality Systems: Our supplier has a documented Quality Management System and are a certified ISO9001: 2000 Company by Quality Certification Bureau Incorporated (QCB) of Canada and accredited to (RVA), the Dutch Council of Accreditation.

Dimensional Tolerances:  The standard tolerances are +/- 0.15 mm per every 25 mm.

Product range: Investment castings in grades of Carbon Steels, stainless steels and copper alloys are manufactured. Alloys handled in carbon steels are EN8, EN9, EN353, 4140, 8630, WCB, etc, in Stainless steels – CF8, CF8M, CK20, CF3, CF3M etc. In copper alloys we do SAE660, C97500 Nickel Silver, Phosphor bronzes etc. Parts like valve bodies, wedge of gate valves, castings for biomedical implants and prosthetics, and general engineering hardware.

Aluminium : We have installed 200 Kg. Skelner oil fired melting furnace and oil fired 200 Kg holding furnace. The permanent mould casting may range in weight of 100 gm to 10 kg.       
The required heat treatment facility is also available. We also would archive the required T5/T6 treatment for hardness, tensile strength and microstructure. The processing standard for metal will be achieved by using cleaner metal and will be porosity free. The hydrogen level will be kept to a minimum and the higher density of metal will also be achieved.
