Multi-Pass Deep Drawing with Annealing — Stainless OEM
Multi-pass deep drawing with intermediate annealing for difficult stainless shells. Used when high draw ratios or irregular geometry work-harden the strip — the same route family… Read full overview
- Focus — Multi-pass draw + intermediate anneal
- Why — High ratio / work-hardening control
- Control — Wall thickness on critical sections
- Used on — Difficult mixer bowls and custom shells
- Material
- SS201 / 304 / 316 (program-specific)
- Volume & MOQ
- MOQs are program-specific — share annual volume tiers for cavitation and landed pricing.
New geometry not previously produced?
Many OEM programs begin with new geometry. With 60+ owned molds, 200+ customer molds under management, multi-pass deep drawing capability, and DFM review, we assess whether your stainless shell can progress from sampling to serial production.
RFQ package should include:
- Engineering drawing or dimensional sample photos with critical dimensions
- Annual volume tiers and target delivery window
- Material grade, thickness, surface finish, and compliance market
- Critical mating and quality features: hub interface, weld load capacity, rim circularity, or cosmetic acceptance criteria
SGS / RoHS / REACH documentation available on request for qualified OEM programs.
Program overview
Multi-pass deep drawing with intermediate annealing for difficult stainless shells. Used when high draw ratios or irregular geometry work-harden the strip — the same route family behind many hard mixer-bowl and custom shell programs.
What this program shows
- Sequenced draws instead of one risky hit
- Intermediate anneal / stress relief when material demands it
- Wall-thickness control on critical sections
- Honest quoting of ops count versus single-pass fantasy pricing
If your part cracked at another shop on a single-pass try, send the print and failure notes. We propose a viable pass plan or a clear no-go.

Specifications
| Focus | Multi-pass draw + intermediate anneal | Why | High ratio / work-hardening control |
|---|---|---|---|
| Control | Wall thickness on critical sections | Used on | Difficult mixer bowls and custom shells |
| Material | 304 / 201 common; 316 per RFQ | Program type | Reference program — not stock SKUs |
Customization from drawing
Quoted from your engineering drawing or approved reference sample — not offered as ex-stock catalog items. Typical adjustable parameters for this forming family:
| Geometry | Cylindrical, flared, spherical, stepped, irregular | Size band | Typical Ø10–350 mm, draw height to ~250 mm (confirm on RFQ) |
|---|---|---|---|
| Thickness | Commonly 0.4–1.0 mm stainless (program-specific) | Route | Single-pass or multi-pass + anneal |
| Finish | As specified after forming | Tooling | In-house; customer mold management |
| Intake | STEP / PDF / sample → DFM (typical 1 business day goal) |
Compliance & documentation
We support appliance and HORECA OEM programs with ISO 9001-aligned QC, material traceability, and third-party tests (LFGB, FDA-oriented food contact, RoHS, REACH) coordinated per purchase order. See our Quality & compliance section for the full documentation matrix.

Drawing-based OEM programs — not retail or ex-stock catalog parts.
- Can this part be ordered as shown from inventory?
- No. Each page is a reference program that documents forming capability on comparable tooling. Your part is evaluated from the engineering drawing or sample — geometry, depth, and mating interfaces may differ.
- Can you manufacture a geometry you have not produced before?
- Yes. Many OEM programs begin with new geometry. We assess DFM, tooling route, and whether the stainless shell can progress from sampling to serial production.
- What inputs are required for a quotation-ready RFQ?
- Engineering drawing or dimensional sample photos, annual volume tiers and target delivery window, material grade / thickness / finish and compliance market, plus critical mating and quality features such as hub interface, weld load capacity, rim circularity, or cosmetic acceptance criteria.
- How are MOQs and lead times determined?
- MOQs and schedules are program-specific. Provide volume tiers and required delivery windows so we can align cavity count, tooling, and production planning.
- Do you provide compliance documentation?
- SGS / RoHS / REACH and food-contact oriented tests can be coordinated per qualified program and purchase order. Request the documentation matrix applicable to your target market.
- Is this website intended for household retail purchasers?
- No. We serve appliance brands, sourcing companies, and B2B importers on OEM deep-drawing and stamping programs.
