Metal Stamping & Formed Metal Parts

Single-hit stamping forms a part in one die stroke — good for simple shapes or low volume. Progressive stamping feeds a metal strip through a sequence of stations in one die set, with each station adding a cut, bend, or form, so a finished part comes off the end of the strip in one continuous run. Progressive tooling costs more up front but drops the per-part cost hard at volume.

Steel, stainless, and aluminum sheet are the common choices, and the metal matters for more than cost — thickness, temper, and grain direction all affect how a part springs back after forming, whether it cracks at a tight bend radius, and how consistent hole and edge quality are across a long run. We review material choice during DFM, before tooling is cut.

Spring-back and die wear are the usual culprits. A formed part relaxes slightly after it leaves the die, and if that's not accounted for in the tool design, dimensions drift from the print. As a die wears over a production run, burrs and slight dimensional creep can show up gradually — parts that measured fine at first-article can drift out of spec thousands of pieces later without in-process checks.

Yes. Stamped brackets, housings, and formed metal parts made on our Shenzhen floor can move directly into finishing and assembly on the same site, so a metal part doesn't ship out to a second vendor for paint, plating, or fastening before it comes back for final assembly.

It depends on the part and the tooling cost that makes sense for the volume — a simple bracket may be cut on a single-hit die cheaply even at modest volume, while a complex progressive-die part only pays for itself at higher volume. Send us the drawing and the expected quantity and we'll tell you honestly which approach fits.
