Production Facilities
We merge our in-house design with our VMC Machines to produce patterns within a short span of time. our products are designed with the help of AutoCAD, and ProEngineer software and optimized through a series of simulations. One 4 axis VMC machine is being used to produce fresh designs with greater speed and perfection. Our company has a melting capacity of 42,000 tons per year of cast iron using 5 cupolas and also has 2 induction furnaces with a capacity of 9000 tons for ductile iron. We produce GGG50 grade of ductile iron.
We are equipped with two mechanized sand plants with separate sand for machine moulding and hand moulding. We have three pairs of simultaneous jolts squeez moulding machines that are capable of producing higher quality castings. Other Machine shop includes lathes, plano millers shapers and drilling machines. Our practice involves usage of black bitumen, environment friendly water based paint, epoxy and primer for painting. We also have extensive container loading facilities.
