What is meant by closed die forging?

Closed Die forging is a type of forging or metal shaping process in which metals is compressed between two shaped dies to produce forged components with precise dimensional accuracy. After forging the surface is smeared with sand paper, and made smooth for excellent surface finish.

Materials suitable for closed die forging

Metals such as carbon steel, alloyed steel, stainless steel, aluminium alloys, titanium alloys, copper alloys, and nickel-based alloy(s) qualify as being appropriate for closed-die forging. This is due to the fact that they all possess outstanding properties of forgeability, as well as good strength, toughness and resistance to wear/corrosion (amongst others), making them ideal candidates when producing high-performance parts typically used in the automotive industry; aerospace industry; railroad industry; oil and gas industry; and heavy engineering industries.

Different types of machines used by closed die forging company

Various types of machines are used by closed die forging company to create precision parts through the following methods/mechanisms: mechanical press, hydraulic press, screw press, drop hammer, upset forge machine, induction heating furnace, trimming press, heat treatment furnace, and CNC machining centre. The use of these machines will produce the most accurately shaped parts with the highest amount of at least 90% from the material they were forged from, leading to superior mechanical properties (increased strength/durability) and dimensional accuracy for all components produced and used in the automotive, aerospace, railway and heavy engineering industries.

Common applications of closed die forging

One of the most commonly used methods for producing precision products with high strength is closed-die forging. Forged components are produced through this method as well as other methods throughout many different industries. For example, some of the industries that utilize this method to produce components are as follows: automotive, aerospace, rail, oil & gas, mining, construction equipment manufacturing, military, power generation, etc.

Applications of components produced through this process include crankshafts, connecting rods, gears, shafts, flanges, valves, bearing races, turbine components and many additional critical pieces that require durability under extreme mechanical loads and stringent tolerances for extended periods of time.

Conclusion

To summarize, the advanced manufacturing method of closed die forging produces precision-engineered components with relatively high strength from many different types of metals. This process involves the use of specialized forging and machining equipment and produces components with superior mechanical properties and dimensional accuracy for the demanding requirements of automotive, aerospace, railway, energy, mining, or heavy engineering applications. The durability and reliability of these forged products make closed die forging a crucial technology in today’s industrial manufacturing supply chain.
