Prototyping Sheet Metal Parts — Tips & Fast Turnaround

Validate designs quickly without sacrificing accuracy. We prototype single samples to short-run lots with in-house laser cutting, CNC bending, spot/MIG/TIG welding, and finishing — all set up for speed and repeatability.

Before You Send Files

● State revision, material grade, thickness, and finish in the file name or header.

● Mark critical faces/features and bending direction; note cosmetic sides.

● Provide STEP/IGES (3D) + DXF (flat) + PDF drawing with key tolerances.

● Tolerances only where function needs it; keep general dims to a sensible default.

Material & Thickness Picks

● Aluminum: 5052/6061 for good bendability and weight; 6063/6082 on request.

● Stainless: 304 for general use; 316 for corrosion; 430 for cost-sensitive.

● Steel: SPCC/CRS for painted parts; HS grades on request. Typical 0.8–3.0 mm.

Bending & Forming (DFM Rules of Thumb)

● Inside bend radius ≈ ≥ 1.0×T (as a safe starting point).

● Hole-to-bend distance ≥ 1.5×T (2.0×T preferred for soft materials).

● Minimum flange height ≥ 2.0×T + inside radius.

● Slot width ≥ T; keep notches away from bend lines; consider grain direction.

Tolerance Stack-Up & Assembly

● Use datums, tabs/pins, or small slots for adjustability during assembly.

● Call out fastener types, PEM nuts/inserts, and weld symbols clearly.

● Reserve tight GD&T only for critical interfaces to keep cost/lead time down.

Finishing & Marking

● Powder coat, anodize, passivation, zinc-nickel plating, silkscreen/engraving.

● Provide color codes (e.g., RAL/Anodize Type/Gloss) and masking areas for threads.

Lead Time & Service

● Prototypes typically in 2–5 days; short-run lots scheduled per quantity.

● English support with quick DFM feedback and clear progress updates.

What to Send for a 24-Hour Quote

● Files: STEP/IGES + DXF + PDF (key dims/threads, finish, cosmetic side).

● Quantity range, target date, and destination country/region.

● Acceptable alternates (e.g., 5052 ↔ 6061, bead-blast ↔ polish) if timing is critical.

NDA & IP Protection

We sign NDAs on request. Drawings and data are restricted to authorized engineers and handled confidentially throughout prototyping and production.

Tip: If your part has tight bends near holes, attach a detail view with exact distances — it speeds DFM and avoids rework.
