An Overview of Forging Processes with Their Defects

description about classification of forging process on the basis of temperature of work piece (hot, cold, and warm forging) and on the basis of arrangement of dies (open, impression and closed-die forging) is given. Die design parameters, die material requirements and selection of proper die materials are briefly discussed.

Closed Die Forging

Closed die forging is distinct from open die forging, in which the die only comes into contact with part of the workpiece at a time. Initial costs for developing the processes and tooling for closed die forging can be quite high, but it is the most cost-effective forging method for high volume production, since recurring costs for each part are very low.

Closed Die Forging - Schuler Group

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.

About Drop Forging and Upset Forging | Green Bay Drop Forge

Closed die drop forging is a steel shaping process whereby a heated steel billet is placed on a lower die mould block, while an overhead, die-equipped ram hammer drives or "drops" down, forcing the metal to fill the contours of the two die blocks. Forging on a drop hammer is carried out in a succession of die impressions using repeated blows.
