Battery Enclosure Stamping Parts

This is not a thin cosmetic cover stamping. The starting material is at least 2.66 mm thick, with a strip width of 660 mm and a 450 mm progression.

That combination creates meaningful cutting and forming load throughout the tool. The carrier has to remain strong enough to move the workpiece through the complete 8-step route without becoming unstable after earlier material has been removed.

For production, we are interested in more than whether the press can make one acceptable stroke. Feeding resistance, strip position, finished geometry and cutting condition need to remain stable as the tool continues running.

The pickled-and-oiled surface also requires controlled handling after stamping so unnecessary scratches, contamination or corrosion exposure are not introduced between production and packing.

The 8-step route allows the work to be divided instead of forcing heavy cutting and forming activity into only a few crowded stages.

For Changdong, the value of those steps is process control. Features can be created when the surrounding geometry is sufficiently stable, and heavy work can be distributed along the tooling instead of concentrating the complete load in one area.

We do not assign generic functions to an OP number without the released project data. What matters for production is that each step leaves the strip in a condition the following step can use consistently.

The final part is judged after the complete route, because an acceptable intermediate condition has value only if it contributes to a stable finished Draw Bar.

A 13.6T production tool is a long-term manufacturing asset. Cutting inserts, guide components and other wear areas will eventually require normal service.

Because Changdong manufactures the tooling, our stamped-parts customers do not need to coordinate independently with another toolmaker every time production feedback points back to the die.

The relevant component can be inspected, serviced and returned to production under the same project data. New first-off parts are then checked before normal batch production continues.

This keeps tooling maintenance in the background of the supply program instead of turning every normal service event into a separate customer-managed project.

Inspection is not useful if the approved part is damaged between the stamping area and the customer's plant.

The packed-parts photograph at the top of this page represents the final stage of the manufacturing route. After stamping and inspection, the Draw Bar components still need controlled stacking and protection appropriate for their geometry and surface condition.

For repeat supply, packing requirements can remain tied to the same part specification so later batches do not leave Changdong under a different handling condition from the approved shipment.

This is how we approach ongoing Battery Enclosure Stamping Parts production: tool build, press production, inspection and packing remain connected until the finished parts are ready to ship.
