EV Stamped Parts

This project uses six single-operation dies rather than one progressive tool. That arrangement can suit medium or large blanks, lower program volumes, or parts that need independent control at each stage. For EV Stamped Parts, the sequence may divide drawing, forming, trimming, piercing, and restriking so that material movement can be corrected between operations. The 390 x 735 mm blank requires reliable locating features and careful handling to prevent orientation errors. Each die should preserve the datums needed by the following operation, because small transfer inconsistencies can accumulate into final assembly problems.

SCGA440-45 is stronger than mild drawing steel, so flange recovery and local springback deserve attention during engineering review. The finished parts may also contain stiffening features, mounting faces, or interfaces with battery and chassis systems. Forming simulations or early tryout observations can help identify areas at risk of thinning, wrinkling, or shape loss. Instead of applying the same correction everywhere, engineers usually adjust local radii, pressure, or restrike conditions according to the actual part response. This creates a more stable process than relying only on nominal drawing dimensions.

Buyers working with automotive stamping companies should define critical dimensions, inspection frequency, surface requirements, and expected production volume before tool release. Changdong can support drawing review for customers seeking an EV stamped parts manufacturer in China or an EV stamped parts OEM supplier. Useful inputs include the part function, mating components, welding points, and whether protective coating must remain intact. For chassis stamping or other structural uses, sample approval should verify both standalone dimensions and fit within the intended assembly condition.

Approval samples should represent stable output after the dies have reached normal working conditions. Reports can separate critical assembly dimensions from general reference dimensions, while photographs document surface condition and orientation. Where the component enters a battery or chassis module, a fit check with the mating structure can reveal issues that a standalone measurement report may miss.
