We make deep drawn metal cups from your CAD file or a napkin sketch. Round, rectangular, stepped, or flanged—if it can be formed, we quote it. Every batch is checked against your tolerance, not a generic standard. We send you the inspection report before shipment, so you approve what arrives.
At a glance: ±0.05 mm tolerance on critical diameters, 0.3 mm to 3.0 mm material thickness, 10 to 500 ton press capacity, 15-day standard lead time, no MOQ. Prototype in 7 days.
| Parameter | Value |
|---|---|
| Material | SPCC, SECC, SUS304, SUS316L, brass, copper, aluminum 5052/6061 |
| Material thickness | 0.3 mm – 3.0 mm |
| Drawing depth | Up to 80 mm (single draw), deeper with multi-stage tooling |
| Tolerance | ±0.05 mm on formed diameters, ±0.1 mm on depth |
| Surface finish | As-drawn, brushed, electropolished, powder coated, zinc/nickel plating |
| Press capacity | 10 – 500 tons (mechanical and hydraulic) |
| Secondary operations | Trimming, piercing, flanging, knurling, thread forming |
| Tooling | In-house design and build; progressive or transfer dies |
| Inspection | CMM, optical comparator, pin gauges, surface roughness tester |
| Batch size | 1 piece (prototype) to 1,000,000 pieces per year |
| Lead time | Prototype 7 days, production 15 – 25 days after tooling approval |
| Certifications | ISO 9001:2015, material mill certificates, RoHS/REACH reports |
1. Batch-traceable quality. Each lot gets a unique heat number and production log. If a problem shows up at your assembly line, we trace it to the exact coil, press, and operator shift. No guesswork.
2. Inspection report per batch. You get dimensional data, material hardness, and surface roughness readings—not a "passed" stamp. Our QC team measures first articles and every 50th piece during production. The report is emailed to you before shipment.
3. One factory for CNC, stamping, springs, and heat sinks. Your deep drawn cup might need a CNC-machined flange, a spring retainer, or a heat sink base. We do all four lines under one roof. You avoid coordinating three suppliers, three shipping dates, and three sets of tolerance arguments.
Deep drawn metal cups are structural shells, housings, and fluid barriers. Real applications we ship today:
The deep draw process work-hardens the material, so your cup gets higher yield strength than the raw sheet. That means thinner walls can replace thicker machined parts—lighter, cheaper, and faster to produce.

Q: Is there really no MOQ? A: Yes, no MOQ. We run 1-piece prototypes for fit testing and 100-piece pilot runs. Production pricing kicks in at 1,000 pieces, but you are never forced to over-order.
Q: What tolerance can you hold on a deep drawn cup? A: ±0.05 mm on formed diameters up to 100 mm. Depth tolerance is ±0.1 mm. If you need tighter, we add a sizing or ironing operation—tell us your critical dimensions on the drawing.
Q: How do you guarantee quality before shipment? A: We run a full first-article inspection (FAI) with a CMM report. During production, we check dimensions every 50 pieces and record hardness and surface finish. The batch report is attached to your packing list and emailed to you.
Q: Do you provide material certificates? A: Yes. Every coil and sheet comes with a mill certificate showing chemical composition and mechanical properties. We also provide RoHS and REACH declarations on request.
