Fully integrated manufacturing, quality and delivery processes are designed so as to ensure flexibility in company's supply chain.

The unit specializes in manufacturing closed and open die forgings of carbon, alloy and stainless steel and has the following facilities.

Tool and Die Shop

Harihar Forging has a state of the art in-house tool and die manufacturing facility comprising multi-axis high speed milling machines. Die manufacturing is a critical task in any closed die forging operation. Our in-house die-making capability enables us to have better control on quality and the final product.

The entire facility is inter-phased with cutting edge 3D modeling software and this ensures good quality tools and dies on a consistent basis. All dies are checked with a prototype before initiating actual production. The following softwares are employed for die design and CNC programming.

  • Cimatron E
  • Solid Works
  • Auto CAD 2014
  • SIMENS NX 8.5

The die shop also consists of a wide variety of in-house dies used for forging generic products used across varied industries, like oil and gas.
