Stamping defects like cracking, wrinkling, scratches, or uneven edges can derail production, but they’re preventable with proper material and process control. Cracking often stems from using overly rigid alloys or tempers—opting for softer tempers (O or H24) with good elongation ensures the disc withstands deep drawing without breaking.
Wrinkling occurs due to insufficient or uneven blank holder force. Adjusting the die and applying consistent pressure keeps surfaces flat, eliminating folds. Surface scratches are typically caused by rough disc surfaces or contaminated stamping tools. Sourcing discs from reliable suppliers guarantees a smooth finish, while regular tool cleaning prevents debris from marring the metal.
Burrs and uneven edges result from dull or misaligned cutting tools. Keeping equipment sharp and calibrated to industry standards ensures clean, precise edges. Additionally, selecting discs with uniform thickness and tight tolerances reduces material stress during stamping. By combining quality materials, proper tool maintenance, and process adjustments, you can significantly reduce defects and boost production efficiency.
