ENGINEERING CONCEPTS

What is the use of forging?

Forging is a manufacturing process where the metal is pressed,pounded or squeezed under great pressure into high strength parts knows as forging.

The process is normally but not always performed hot by Pre-heating the metal to a desired temp before it is worked.

Why use forging and where are they used ?

Create parts that are stronger than those manufactured by any other metal  working process.

  • Dynamic load.
  • Impact load.
  • Cyclic load and fatigue load.
  • High pressure.
  • High torque.
  • Safety and reliability.

Forging advantages:

Directional strength :

  • Forging’s refines grain structure and develops the optimum grain flow.
  • Which impart desirable directional properties such as tensile strength,Ductility,impact toughness,fracture toughness and fatigue strength.

Structural integrity:

  • Forging’s  are free from internal voids and porosity.
  • The process achieves very consistent material uniformly which results in uniform mechanical properties and a uniform predictable response to heat treatment.
  • Impact strength.
  • Optimum material utilization.

Limitations:

  • Initial cost of equipment’s/dies is high in addition maintenance costs of tools and dies are involved.
  • Forged part costs more than casting part.
  • Intricate and cored shapes cannot be produced by forgings.

Common applications:

  • Automotive and truck.
  • Transmission shaft and gears.
  • Differential Gears.
  • Connecting rod.
  • Crank shafts.
  • Rockers arm.
  • pitman arm.
  • Wheel spindle’s.
  • Axle beams and shafts.
  • Drive shafts.
  • Clutch hubs.
  • Universal joints.
  • Gear shift level.
  • Steering arms.
  • Torsion bars.
  • Engine value.
  • Agricultural machinery and equipment.
  • Values fitting.
  • Oil filed applications for high pressure application.
