Forge in action at Edgar Allen's steel foundry, Sheffield, South Yorkshire, 1963. Impression die forging pounds or presses metal between two dies (called tooling) that contain a precut profile of the part which is being manufactured. Parts weighing from a few ounces to 60,000 pounds can be made using this process. Some of the smaller parts are actually forged cold.
