Titles: Forging in Closed Dies (:07-:58) was made by the Drop Forging Association. In a log cabin, a man makes a horseshoe on an anvil. The man is forging which is to make or shape (a metal object) by heating it in a fire or furnace and beating or hammering it. Billets of steel are brought to forging heat in a furnace. A man uses a modern machine to forge. The machine beats down the metal (:59-2:43). A man hits hot metal on an anvil. A machine slams down on metal and it emits a huge fire. A woman gets into a car. They show a Studebaker car without it's side and roof. The cylinder block is shown. Fan blades. Gears move. Differential gears. A chassis. Parts of the car move, these parts needed forging originally. A connecting rod. The die in which the rod is made is shown. A forging drop hammer is where the rod will be made. Steel is heated in a furnace. The hammer drop down onto the molten piece (2:44-6:22). The finished connecting rod. The structure is shown. A forging drop hammer machine with a worker next to it. The machine is shown working as it drops. The hammer keeps drooping. The air lift type machine (6:23-8:34). A steam drop hammer machine is shown and explained. The men place metal inside of it. Steam assists. Steam hammer keep dropping. The hammerman uses different dies for forging a piece. Multiple dies are shown and what they do to the metal. What each side of the dies does is explained in detail. A connecting rod through various stages is shown (8:35-11:22). A forging machine or upsetter. Men work with the upsetter machine. Finished forging is shown. A wood model shows how a header works - a three cast die. Inserting a bar into the die cavity is shown with a wood piece and a model to explain. Grain structure is shown and explained. Another means of forging is a mechanical press. Men work with this machine. Press smashes metal down to a flat impression (11:23-15:02). A hydraulic press machine. Aluminum is being made for a jet engine and this machine helped assist. Metal is on fire in the machine. Forging roll machine. Partly finished forgings are being placed in the machine. Smith forging is used sometimes, this is shown and explained. A trip hammer. Hammer machine slams down (15:03-17:42). Die blocks. A die block being made and explained. A man outlines the die impression A machine cuts into the die. Completed forging dies are installed into the hammer machine. High grade steel is required. Chemical analysis, physical properties, microscopic analysis. Steel pieces are cut and sheared. Forging multiples. Tiny pieces of steel (17:43-20:18). A ton of steel is moved by a crane. Multiples from which forging is made. PIeces of finished steel. Automobile crankshaft forging. Crankshaft forging unit. They make the crankshaft in the machine. Fiery finishing blows to the metal (20:19-22:25). Finished crankshafts. Dental tools. Forceps start as a bar of alloy stainless steel. A man forges in a machine. A billet of special alloy steel is carried by a machine to a forging machine. The hammer slams down on the machine and smoke and flame shoot out (22:26-25:07). Modern turbojet engine. A block of steel is being moved to a forging machine to be smashed down to its proper form. The wheel forging is moved. Blades for the engine are being finished forged. The blades in a finished wheel. Men walk towards a military jet, a Grumman F9F Panther. The pilot gets into the plane. The plane flies through the air (25:08-27:37). End credits (27:38-27:49).
