‘锻压’ (duàn yā) is a compound noun referring to the industrial metalworking processes of forging and pressing—two closely related mechanical shaping techniques used to deform metal while it’s hot or cold, improving its strength and structural integrity. The first character, 锻 (duàn), means ‘to forge’—heating metal and hammering or squeezing it into shape; the second, 压 (yā), means ‘to press’ or ‘to compress’, often using hydraulic or mechanical force without heating. Together, they describe a broad category of metal forming operations common in manufacturing, especially in producing automotive parts, machinery components, and aerospace hardware.

This term appears primarily in technical, engineering, and industrial contexts—not in daily conversation—and is often found in factory names, equipment specifications, or process documentation. It emphasizes the physical deformation of metal rather than cutting or casting, and is frequently paired with words like ‘设备’ (equipment), ‘车间’ (workshop), or ‘工艺’ (process).
