Castings

Valiant is well positioned to supply a range of Ferrous and non-ferrous castings (grey cast iron, ductile iron or SG iron, alloy of aluminium, steel, copper, etc.), produced of gravity (green sand or die-cast) and investment processes. Yield weight of the produced castings ranges from 50 grams (0.11 lbs) to 750 kgs (1654 lbs) per unit approx. and confirms to major international standards and grades. for E.g. parts such as Exhaust manifolds, spring brackets, shackles, clutch plates and differential body. A few sand castings are shown here

The following tables gives an insight of the grades of grey iron castings we can supply to you as per Indian standard IS 210:1978 and to their equivalent German standards as per DIN 1691:1985

* Representative numbers and does not specify any grade
We can supply intermediary DIN grades such as GGG40.3, GGG50.3 and others not mentioned here. The castings can be produced to required Physical (Tensile properties and elongation %) and chemical properties (metal composition). Having said that we can supply castings to ASTM, EN and any other international standard.

New product development

We can undertake prototyping of your castings in India. Our new product development service involves right from preparation of designs and drawings (for mould making and machining separately), pattern making, tool design and development for moulds and machining processes respectively during the development cycle. Our engineers are well trained and have sound technical knowledge in development of new castings (both sand and die cast), therefore quality of end product can be assured at all times. Our company can act as your Indian office to develop, manage and control the use of such tools for production in India with the supplier of our buyer’s choice from time to time.  We safeguard the interests of the buyer and IP of their products in India at all times.
