Your AI server design is only as reliable as the shielding that protects it. We build EMI shields and brackets to your exact drawing, not from a catalog. Every part is verified before shipment with a full inspection report.
At a glance: ±0.05 mm tolerance on critical features, 7-day standard lead time, no MOQ, and full material traceability. We are a precision manufacturing factory in Dongguan, China, with 20 years of metal stamping experience.
| Parameter | Value |
|---|---|
| Material | Stainless steel (SUS301, SUS304), galvanized steel (SGCC, SECC), aluminum (5052, 6061), copper alloy (C1100, C17200) |
| Thickness range | 0.1 mm – 3.0 mm |
| Tolerance | ±0.05 mm (critical dimensions), ±0.10 mm (standard) |
| Process | Progressive die stamping, compound die stamping, CNC punching, bending, tapping, countersinking |
| Surface finish | Bright annealed, nickel plating, tin plating, zinc plating, powder coating, passivation |
| Max part size | 600 mm x 400 mm |
| Min part size | 5 mm x 5 mm |
| Batch size | 1 piece to 1,000,000 pieces (no MOQ) |
| Lead time | 3 days for samples, 7 days for production (typical) |
| Inspection | CMM (coordinate measuring machine), optical comparator, salt spray test, hardness test |
| Certifications | ISO 9001:2015, IATF 16949 (on request), material certificates (EN 10204 3.1) |
We use 25-ton to 250-ton high-speed presses (up to 600 strokes per minute) and precision wire-cut dies. Our toolroom builds and maintains all dies in-house, so we control quality from die design to final part.
1. Batch-traceable quality. Every lot gets a unique batch number. We track material heat number, die number, and operator ID for each batch. If a field issue appears, we trace it back to the exact stamping run. You get a clear chain of custody, not a vague "we checked it."
2. Inspection report per batch. You receive a dimensional report with actual measured values, not just a pass/fail note. We include CMM data for critical features, surface finish readings, and material hardness results. This report is signed by our QC engineer and available within 24 hours of shipment.
3. One factory for CNC + stamping + spring + heatsink. Your EMI shield often needs a spring finger or a heatsink interface. Instead of coordinating three suppliers, we do it all under one roof. This cuts your logistics cost, shortens your lead time, and eliminates tolerance mismatch between mating parts. One drawing, one responsible party.
Our custom metal stamping parts are used in real, high-heat, high-frequency environments:
These parts must hold their shape after repeated thermal cycling (0°C to 85°C) and resist corrosion in humid environments. Our stamping process and surface finishes are selected for exactly that.

Q: What is your MOQ? A: No MOQ. We stamp 1 prototype or 1 million pieces at the same tolerance. For small batches, we use a simplified die to keep tooling cost low. For large batches, we use progressive dies to maximize speed.
Q: How do you guarantee tolerance and quality? A: We use in-process SPC (statistical process control) on every run. Our QC team measures the first article, every 50th piece during production, and the last article. We send you the full inspection report with the shipment. If any dimension is out of spec, we sort 100% and rework at no cost.
Q: What is your lead time for stamped parts? A: Sample lead time is 3-5 days after tooling approval. Production lead time is 7 days for standard parts, 10-14 days for complex parts with multiple bends and plating. We ship worldwide via DHL, FedEx, or air freight.
Q: Can you provide material certificates? A: Yes. We provide EN 10204 3.1 material certificates for steel and aluminum, plus plating thickness certificates. We also provide RoHS and REACH compliance documents. All material is purchased from certified mills, and we keep the certificates for 10 years.
We are a made in China precision manufacturing partner, not a middleman. Send us your 2D or 3D drawing (STEP, IGES, PDF, or DXF) and we will respond with a firm quote in 12 hours. We will confirm material, tolerance, surface finish, and lead time before you commit.
