Steel Coil for Stamping: Specify for the Actual Draw

Send the drawing revision, material orientation, draw depth, corner radii, holes, flanges and critical appearance faces. Show the blank shape and the order of drawing, bending, trimming and piercing. Mark the feature or surface that currently limits the process.

Attach a sample or prior run record if one exists. A similar part made elsewhere is a question for the trial plan, not proof that the same coil will work with a different die, lubrication or press setup.

Mark which face contacts the die, which face remains visible, and where lubricant, cleaning, welding or coating follows stamping. Set the required finish or coating identity for the material under review and describe the surface condition to be accepted before and after forming.

Ask the processor to define its lubrication and cleaning trial for the actual tool and material. Do not infer that a coil finish, oil condition or supplier description will prevent marks, cracking or coating damage in an untested process.

Send the drawing revision, operation and tool sequence, candidate material identity, thickness and width, surface or coating, coil handling limits, required documents, forecast volume and first-article criteria. Ask ZIVO STEEL to confirm the exact available coil configuration, order exceptions and any processing responsibility before the purchase order is issued.

The ordering engineering team should approve the sample and acceptance plan. At receipt, compare the lot documents and agreed tests with the quote rather than treating an application page as a blanket stampability warranty.
