Closed Die Forging

Introduction to Closed die forging

Closed die forging is a metal forming process that involves the use of metal dies to shape a workpiece in a single operation. The dies are used to shape the metal by applying a high-pressure force in a closed environment, creating a forging that is stronger than the original material. Closed die forging is a process that is used to create complex and intricate parts, and the process is capable of producing parts with high accuracy and repeatability. It is commonly used in the automotive and aerospace industries, as well as in the production of industrial parts.

What is closed-die forging?

Closed-die forging is a metal forming process that involves shaping metal between two or more dies that come together to form a desired shape. The dies are typically made from hardened steel and can be used to form complex shapes with tight tolerances. Closed-die forging is a common process for producing parts such as gears, shafts, and other machine components.

Key Benefits of Closed-Die Forging

  • Superior Strength: Closed-die forging produces parts with superior strength due to work hardening and grain structure refinement. The closed-die forging process involves multiple compressive forces that work-harden the metal, resulting in parts with higher yield and tensile strength than parts produced by other manufacturing processes.
  • Improved Dimensional Accuracy: Closed-die forging offers improved dimensional accuracy when compared to other forging processes. The process requires the use of precise dies to shape the metal, and the forging pressure ensures the metal is compressed into the desired shape.
  • Reduced Material Waste: The closed-die forging process creates parts with lower material waste than other processes. The process requires only one piece of material, which is formed into the desired shape without any extra material.
  • Improved Surface Finish: Closed-die forging produces parts with an improved surface finish compared to parts produced by other processes. The forging pressure compresses the metal, resulting in a smoother surface finish.
  • Cost Efficiency: Closed-die forging is cost-efficient because it requires fewer steps than other processes, which reduces labor costs and time. The process also requires fewer materials, which reduces material costs.

Forging parts for different industries using Close-die forging

We manufacture several forging parts for various industries, some of are them mentioned below:

  • Automotive: A wide range of automotive parts, including crankshafts, gears, axles, shafts, bearings, connecting rods, camshafts, and pistons. It can also be used to produce complex components such as brake discs, brake drums, flywheels, and steering knuckles.
  • Aerospace: A variety of aerospace components, including airframe parts, engine components, structural components, landing gear, and wheels. Additionally, closed-die forging can be used to produce high-performance components such as turbine blades, compressors, and other specialty parts.
  • Oil & Gas: A variety of parts for the oil and gas industry, including valves, pipes, fittings, flanges, and valve bodies. Additionally, closed-die forging can be used to produce components for downhole tools, such as drill bits, stabilizers, and reamers.
  • Defence: A wide range of defence components, including armour plates, vehicle hulls, gun barrels, gun mounts, ammunition components, bayonet blades, and other various parts for tanks, artillery, and other military vehicles. It can also be used to make military-grade fasteners and fittings, as well as various components for aircraft, ships, and other defence infrastructure.
