鍛造

Film Overview Production: Iwanami Film Productions Planning: Ministry of Education Black and White, 25 minutes 42 seconds This film aims to deepen understanding of forging by demonstrating its significance and actual processes. It reveals the meaning of forging through tests that apply force to the same material in various ways, observing how the material's quality changes depending on the application of force, and through continuous observation of changes in crystal planes due to temperature changes using a high-temperature vacuum microscope. It also showcases the practical aspects of forging by showing the manufacturing processes of front axles and crankshafts in an automobile factory.
