What This Collection Delivers in Hard Numbers This is a family of stamped brackets and mounts for electronic enclosures, PCB supports, and chassis frames. You get flatness within 0.05 mm, hole-to-ho
This is a family of stamped brackets and mounts for electronic enclosures, PCB supports, and chassis frames. You get flatness within 0.05 mm, hole-to-hole tolerance of ±0.05 mm, and edge runout under 0.03 mm — verified on every batch. Parts are made from 304 stainless steel, SPCC cold-rolled steel, or C17200 beryllium copper, with hardness up to 42 HRC after heat treatment. Lead time is 15 days for standard tooling, 7 days for existing dies. No MOQ applies — order 50 or 50,000 pieces at the same unit price structure.
Most stamping shops quote ±0.1 mm as standard. Our Precision Stamped Electronic Brackets Collection runs at ±0.05 mm because we use progressive dies with tungsten carbide inserts and a 250-ton high-speed press (120 strokes per minute). Each die is serviced after 50,000 hits — not after failure — which keeps burr height below 0.03 mm and prevents die rollover. For critical mounting holes, we add a secondary coining step that flattens the material to 0.01 mm flatness over a 100 mm span. This is what allows your PCB or heatsink to seat flush without shims or rework.
Choose from four base materials: SPCC (yield 210 MPa), SUS304 (yield 520 MPa), C17200 beryllium copper (hardened to 38–42 HRC), and 5052 aluminum (for weight-sensitive designs). Heat treatment is done in a vacuum furnace to avoid oxidation — we reach 42 HRC on beryllium copper, 30 HRC on SPCC after quench and temper. Surface finish options include bright anneal (Ra 0.8), nickel plating (5 µm), and passivation for stainless. If you need a specific plating thickness, we hold it to ±10% of spec, not the industry standard of ±20%.
Every order — even a 50-piece prototype run — gets the same inspection protocol. We use a CMM (Coordinate Measuring Machine) with 0.002 mm resolution to check hole positions, plus a profilometer for surface roughness. Runout is measured on a granite surface plate with a dial indicator. You receive a full dimensional report (PDF) with each shipment, showing actual measurements versus your drawing. No exceptions. If we find a deviation beyond ±0.05 mm, we re-run the part, not just the die — this is why our return rate from electronics customers is below 0.3%.
For the Precision Stamped Electronic Brackets Collection, we offer three tooling tiers. Tier 1: existing universal dies (no tooling cost, 7-day lead time, limited shapes). Tier 2: simplified dies for flat brackets under 50 mm — $300–$800 tooling, amortized over your first order. Tier 3: full progressive dies for complex bends and multiple holes — $1,500–$3,000, but these pay back if you order over 5,000 pieces. Because we are a factory in Dongguan, not a trading company, you pay only the tooling steel and machining cost — no middleman markup. Send your drawing, and we will quote tooling separately from piece price so you see the exact breakdown.
Stamping wins on cost and speed for volume — at 1,000 pieces, a stamped bracket costs $0.15–$0.40 each, while a machined mount runs $1.20–$2.50. Stamping also gives better consistency over 10,000 pieces because the die does not wear like a cutter. However, CNC is better for prototypes or parts with deep pockets and undercuts. If you are still deciding between processes, read our metal stamping vs CNC machining for prototypes guide. For tooling selection on secondary operations, check the CNC cutting tool selection guide to see how we finish edges. And for surface requirements like plating or powder coat, refer to the CNC machining tolerances guide — it covers what we can hold on stamped parts versus machined ones.
We pack in anti-static trays with EPE foam dividers — no loose parts rattling in plastic bags. Each box gets a label with batch number, material heat number, and date code. For SMT-line users, we offer tape-and-reel packaging for small brackets under 20 mm, with 2,000 parts per reel. Batch-to-batch consistency is guaranteed by our SPC system: we track hole diameter, bend angle, and material thickness on every 100th part during production. If the trend drifts beyond 1.33 Cpk, we stop the press and adjust — not after the run ends, but during it. This is precision manufacturing made in China, engineered to the same standard as any German or Japanese shop.

There is no MOQ — we accept 50 pieces as a trial run, and the unit price stays the same as for 5,000 pieces, only tooling amortization changes.
Yes, we make custom shapes from your 2D or 3D drawing, with the same tolerance and finish options, and tooling costs start at $300 for simple flat parts.
Every batch, regardless of size, goes through CMM inspection and a dimensional report; we do not skip QC for low-volume orders.
For a new die, 15 days from drawing approval to first articles; for existing dies, 7 days to ship.
