Machined Components out of
Castings, Forgings and Bar-stock

Over the past decades, we have manufactured more than 3,000 different precision Machined Components for various applications, some of which are very critical in nature. This involves maintaining high tolerances along with parameters like surface finish, flatness, roundness and cylindricity.

We have also successfully developed cost effective and simple solutions to critical subassemblies through innovation in machining and assembly.

We are very familiar with raw materials including sand castings, shell moulded castings, investment castings, die castings, forgings and bar-stock out of a variety of materials ranging from Grey Iron, Ductile Iron, Stainless Steel to Aluminum, Brass, High Alloy Steels, and Low Carbon Steels.

We can provide you with fully Machined Sand Castings in Grey Iron in a variety of grades including I.S. 210: Grade FG-150, 200, 220, 260, 300 and 350 with additions of alloys wherever required and equivalent to other international standards.

We can also supply Sand Castings in Spheroidal Graphite Iron or Ductile Iron in a variety of grades including I.S. 1865: Grades 400/10, 400/15, 500/7, 600/3, 700/2 and equivalent to other international standards like DIN, EN, ASTM, etc.

These castings can be used in a variety of applications including Machined Tools, Pumps, Valves, Gear Boxes, Compressors, Oilfield Components and other General Engineering fields.

We can also provide you with fully Machined Shell Mold Castings, this process offers better surface finish and better dimensional tolerances on the casting. A heated metal pattern is covered with a mixture of sand and thermo set plastic. This causes a skin of about 0.125 inches of sand / plastic mixture to adhere to the pattern. This skin is removed from the pattern to form the “Shell Mold”. This process can produce complex part with good surface finish and dimensional tolerance.

As another alternative to Sand and Shell Mold Castings, we provide fully Machined Investment Castings – for Pumps, Actuators, Valves, Pumps Impellors and General Engineering. Precision Investment castings by “Lost Wax Process” in a variety of materials including Stainless Steel, Heat Resistant Steel, Corrosion Resistant Steel, Tool Steel, Brass, Bronze and Aluminium alloys, This process is accepted world wide as one of the most efficient and economical manufacturing technology for precision and intricately shaped parts. Key advantages included intricacy in shapes, close dimensional tolerances which eliminates most machining, superior surface finish, closer control of metallurgical characteristics and wider range of Alloys – Ferrous and Non-Ferrous. Main stages of the lost wax process include – Injection of the wax into the dies, assembly of the patterns into a casting unit (Tree), covering of trees with refractory material (Shelling), dewaxing and sintering of shells, pouring of required metal into shells and finally removal Ceramic shells and heat treatment. Surface treatments like pickling, passivating, mechanical and electro polishing, hot dip galvanizing etc. are also conducted.

We provide a full range of Heat Treated and Machined Forgings and Assemblies. Materials include Carbon Steel, Alloy Steel, Stainless Steel, Die Steel and Hot and Cold working Tool Steel. Industries served include Machine Tools, Oilfield, Gear and other General Engineering.
