Process Overview

Adopting the latest Technology for Efficient and Reliable Manufacturing

Forging process overview

Forging is a manufacturing process involving the shaping of metal using localized compressive forces of a hammer or a die (Open Die & Closed Die). Forgings are broadly classified based on the temperature at which it is formed as Cold, Warm & Hot forging. For the latter two, the material is heated up to a certain range of temperature. Depending on the type of die used the closed die shall provide better dimensional control and strength. To meet the increasing demand for customized part requirements many new forging technologies have evolved for manufacturing precision forged components for various engineering applications.

It is used to produce seamless rings varying in size from a few inches in diameter and weighing less than a pound to over 20 feet in diameter. We provide ring rolling forging services for manufacturing high-strength forged rings for industrial and heavy engineering applications.

Part is forged with the help of four dies arranged in one plane acting simultaneously in radial direction. This method is suitable for producing stainless steel forgings, alloy steel forgings and forged shafts for Oil & Gas and Automotive applications.

It involves locally heating a metal bar and then, while holding it firmly with special tooling, applying pressure to the end of the bar in the direction of its axis to deform it. This process is commonly used for manufacturing die forged components with localized cross-sectional enlargement.

It is done by deforming metal and flowing it into a chamber, and then compressing the metal while it is inside the chamber at extreme temperatures. Extrusion forging supports the manufacturing of complex aluminum forgings and precision forged components with improved structural integrity.

  • It is a manufacturing process which involves shaping of metal through hammering, pressing, or rolling. It can be broadly classified as Open die forging and Closed die forging.
  • The various types of forging process that we can undertake for your parts are ring rolling, radial forging, upset forging, extrusion forging etc. For more details, please refer the Overview section of this page. These processes are widely used for producing precision forged components for critical applications.
  • Forged parts have higher strength and toughness and are less susceptible to cracking and shearing under compressive load. Forgings have minimal defects which can be refined by re-working.
  • They have a better response to heat treatment and have a lower cost over component life.
  • Castings are preferred to make more complex shaped parts with varying thickness.
  • Forged parts are commonly found at points of stress and shock. Automotives such as cars and trucks consist of more than 250 forged parts most of which are produced from carbon or alloy steel. Few of the parts include connecting rods, crankshafts, gear and pinion, universal joints, rocker arms etc.
  • Other industries which require forgings include Aerospace and Defence, Oil & Gas, Steel, Valves etc. We can provide carbon steel forgings, stainless steel forgings, alloy steel forgings, and aluminum forgings to support these critical industrial sectors.
  • There can be multiple imperfections in a forging which if present prominently can be termed as a defect. Few of them are :
    • Unfilled section – Some part of the forging section remains unfilled
    • Cold shut – It includes small cracks at the corners
    • Scale pits – Due to improper cleaning of forged surface
    • Die shift – Due to misalignment of upper and lower die
    • Residual stress and Flakes – Due to improper cooling of forge products
    • Surface cracking – Due to excessive working on the surface at low temperature
  • Chemical analysis – To ascertain the chemistry of the material usually done by spectrometry
  • Mechanical testing – To verify the mechanical properties such as strength, hardness, and ductility. Various tests performed include hardness test, tensile test, bend test, fracture toughness, fatigue test etc
  • NDT – To verify any surface or internal defects in forging. We perform Ultrasonic, Radiography, Magnetic particle, and Liquid penetrant tests
  • Metallurgical test – To evaluate the physical characteristics of the forged material and check for any defects. This includes microstructure, macrostructure, and grain size
