This part is formed using a progressive die, with one end bent into a complex J-shaped hook through consecutive angles (94°, 99°, 102°), requiring high precision at each station to maintain accurate angles and prevent deformation as the material moves through the process. The part must also pass a special “TS:A” inspection standard (a paper-tear test to check edge sharpness) — if the burr is sharp enough to tear the paper, it’s considered defective and must be manually reworked, so controlling burrs and edge sharpness after stamping requires extra care beyond typical standards.
