What Causes Burrs and Scratches on Stamped Metal Parts and How Can They Be Prevented?

Burrs and scratches on stamped metal parts come from two sources. Worn dies or wrong clearance cause burrs. Handling between processes usually causes scratches. Both are preventable at the source. The fix starts with the die, not with post-production repair. Dies need regular maintenance and correct clearance for your material thickness.

Prevention also means protecting the surface after stamping. Parts should move through deburring, then controlled handling through welding and surface treatment. Ask your supplier which controls they run. Look for documented die maintenance and a defined part flow. Xinjiuxinji reviews burr and scratch risk in a free DFM review before production.
