About Ultrasonic machining
Press forging is a processing method that applies a large compressive force to a material using dies and press machines, causing plastic deformation. It has the characteristic of densifying the crystal structure within the material, thereby improving its strength and toughness. Depending on the processing temperature, it is classified into hot, warm, and cold forging; hot forging, in particular, enables large deformations, while cold forging offers superior dimensional accuracy. It is widely used in the manufacturing of critical safety parts that require high reliability and durability, such as automobile crankshafts and connecting rods, aircraft components, and construction machinery gears. Because it is formed by pressing rather than striking, internal stress is easier to control, and it also excels in mass productivity, making it an indispensable foundational technology in the manufacturing industry.
