Closed Die Forging Nickel Alloy Nickel Forgings

Closed Die Forging is a forging process in which dies move towards each other and covers the workpiece in whole or in part. The heated raw material, which is approximately the shape or size of the final forged part, is placed in the bottom die. The shape of the forging is incorporated in the top or bottom die as a negative image. Coming from above, the impact of the top die on the raw material forms it into the required forged form.

A key step in closed die forging is the design and the production of the dies, process which is part of the know-how of the manufacturer. Most common used forging dies material are tool steels. For the high material cost and machining cost, cost of forging dies are always much higher, but it is one time cost, will not be charged from our customers for next batch production. Unlike the open die forging, suitable to manufacture also individual parts, the close die forging is used to manufacture series production as this is particularly convenient to absorb the costs the dies. The close die forged product shows several advantages like the typical flow lines of the material along the profile of the component, beneficial particularly on mechanical components put in service under cyclic fatigue. This process allows furthermore to use reduced over-dimensions, feature which allows cost savings on input weights as well as on final machining due to less material to remove. The close die forging process is typically used for critical components, in our case on railway, petrochemical, electrical, lifting and safety system, industrial and agricultural machinery sectors.
