Deep drawing
What are the common deep drawing defects and their causes?
Answer
What a complete RFQ contains: drawing and 3D model at the same revision, material grade and temper, volume, finish, critical tolerances and required documentation. Also the five questions to ask about every quotation, the wall thickness measurement position, and the four IMDS high-risk points on stamped parts. 10 Deep drawing defects and remedies · PDF Wrinkling, tearing and fracture, earing, excessive thinning, springback, orange peel, draw marks and bottom fracture - each with its appearance, usual cause and the tooling-side remedy.

Pitting can be localized or continuous; individual pits are called pockmarks, and severe cases are termed pockmarked. Coarse grain-induced pitting is commonly known as orange peel.

What an engineer still needs from you
- material and material condition (grade, temper)
- material thickness, plus the key diameter, height and wall thickness
- tolerances, burr direction and the visual acceptance standard
- annual volume - it decides whether tooling is single-hit, progressive or transfer
- surface finish, and any secondary machining, annealing or plating
Next step. Send the drawing for a manufacturability review, or send the part data for a process and cost route.
