Quick Answer: Custom Metal Stamping Services

Metal stamping is a high-volume manufacturing process that forms flat metal sheets into precise custom components using dies and stamping presses. Typical applications span four major sectors:

Automotive brackets, clips and structural mounts
Electrical terminals, busbars and connector contacts
Appliance housings, structural supports and panels
Industrial mounting hardware, covers and enclosures

Metal stamping becomes cost-effective when production quantities exceed 1,000 pieces and consistent dimensional repeatability is required across the entire batch. Progressive die stamping achieves cycle times under 1 second per part at volumes above 50,000 units.

What Can We Stamp?

Four stamping methods cover virtually any thin-metal component requirement. Each technique targets a distinct geometry and production volume profile — choosing the right one directly affects unit cost and lead time.

Four metal stamping process types: progressive die, deep draw, precision stamping and bending forming

Progressive Die Stamping

Best for: High-volume production (10,000+ pcs)

A single strip of coil stock advances through multiple stations within one die set — cutting, bending, forming and coining happen in successive hits. This method delivers the lowest per-part cost at scale, with cycle times under 0.8 seconds per hit.

Typical output: brackets, clips, washers, small flat parts

Deep Draw Stamping

Best for: Cups, housings, containers

A flat blank is radially drawn into a die cavity by a punch, creating seamless cylindrical or box-shaped parts without welding or joining. Draw ratios up to 2:1 are standard; multi-step draws achieve deeper profiles.

Typical output: sensor housings, battery cups, filter shells, enclosures

Precision Stamping

Best for: Electrical terminals, connectors

Fine-blanking and micro-stamping techniques produce parts with ±0.02 mm dimensional accuracy and clean shear edges without secondary deburring. Ideal for thin-gauge copper and brass contact components.

Typical output: contacts, terminals, lead frames, fine-pitch connectors

Bending & Forming

Best for: Brackets, frames, structural parts

Press brakes and CNC forming centers create angled, U-shaped, and complex multi-bend geometries from sheet stock. Cost-effective for lower volumes or larger components that do not justify full progressive die investment.

Typical output: mounting brackets, chassis frames, shelf supports, L/U/Z profiles

Metal Materials Available for Stamping

Material choice determines corrosion resistance, conductivity, formability and unit cost. Below are the six alloys most frequently specified by our OEM buyers, with typical application segments and forming considerations.

Six metal material sample blocks: stainless steel 304, 316, SPCC steel, aluminum 5052, copper and brass

Material	Thickness Range	Formability	Typical Application	Key Property
Stainless Steel 304	0.3–3 mm	Good	Industrial equipment brackets	Corrosion resistance, weldability
Stainless Steel 316	0.3–2 mm	Moderate	Medical & marine hardware	Pitting resistance, chloride tolerance
SPCC Cold-Rolled Steel	0.5–4 mm	Excellent	General hardware & enclosures	Low cost, easy forming
Aluminum 5052	0.3–3 mm	Excellent	Lightweight structural parts	Weight reduction, anodizable
Copper C110	0.1–2 mm	Very Good	Electrical contacts & busbars	Electrical conductivity
Brass C360	0.2–2 mm	Excellent	Connectors & terminals	Machinability + conductivity

Material Selection Decision Guide

Choose Stainless Steel If You Need

Corrosion resistance for outdoor or wash-down environments, food-grade compliance, long service life without plating, high-temperature stability.

SS304 for general industrial — SS316 for marine/medical

Choose Aluminum If You Need

Weight reduction in moving assemblies, anodized color finishes, heat dissipation in electronic enclosures, easy forming for complex bend geometries.

Al5052 for structural — Al6061 for anodizing

Choose Copper / Brass If You Need

High electrical conductivity for contacts and busbars, spring-back tolerance in terminals, low friction in sliding contacts, decorative gold finish on brass.

C110 copper for conductivity — C360 brass for machinability

When Should You Choose Stamping Over CNC?

Both stamping and CNC machining produce precision metal components — but they serve fundamentally different production profiles. Stamping excels at high-volume, thin-sheet parts; CNC excels at complex 3D geometries and low-volume prototypes. Understanding this trade-off is essential for procurement decisions.

Side-by-side comparison of metal stamping production versus CNC machining process

Factor	Stamping	CNC Machining
High Volume	Excellent — cycle time <1 sec	Moderate — 5–45 min per part
Tooling Cost	Higher ($2K–$8K die set)	Lower (no dedicated tooling)
Unit Cost at Scale	Very low ($0.05–$2 per part)	Higher ($5–$50 per part)
Complex 3D Features	Limited — flat + bends only	Excellent — full 3D freedom
Production Speed	Excellent — hundreds per hour	Moderate — hours per batch
Material Thickness	0.2–6 mm sheet only	Any thickness / solid block
Dimensional Repeatability	Excellent — die-controlled	Good — program-controlled
Prototype Phase	Slow — die must be built first	Fast — program in hours

Decision Rule: Choose Stamping When

Volume > 5,000 pcs

Stamping unit cost drops dramatically above 5,000 units because the die investment amortizes across the production run. Below this threshold, CNC or laser cutting is usually more economical.

Thin Metal Sheet Parts

Components under 6mm thickness with flat or bent profiles are stamping’s natural domain. CNC wastes material and time milling thin sheets that a press forms in a single stroke.

Consistent Dimensions Required

Once a die is set, every part is identical — dimensional variation comes from die wear, not operator skill. For tight batch-to-batch repeatability, stamping is superior to manual CNC setup changes.

5 Common Stamping Design Mistakes (and How to Fix Them)

These five errors account for 80% of DFM failures in stamped component orders. Avoiding them reduces tooling cost, shortens lead time and eliminates batch-to-batch variation.

Poor design versus good DFM design comparison for stamped metal parts

1. Walls Below Minimum Thickness

Walls thinner than 0.3mm in steel or 0.5mm in aluminum distort during stamping and fail to hold tolerance across the batch.

Fix: Keep walls ≥0.5mm for steel, ≥0.8mm for SS, ≥1.0mm for aluminum. Use rib stiffeners instead of thickening walls.

2. Sharp Internal Corners Without Radii

Zero-radius corners concentrate stress, cause cracking at bend lines and increase die wear by 3–5× compared to radiused corners.

Fix: Specify R≥0.5mm on all internal corners. Progressive dies naturally impart radii; confirm in the drawing.

3. Over-Specified Tolerances on Non-Critical Features

Applying ±0.02mm to mounting-hole positions that only need ±0.1mm increases die complexity and cost by 30–50%.

Fix: Assign tight tolerance only to mating/contact surfaces. General dims: ±0.1mm is standard and cost-free.

4. Excessive Bend Relief Notches Missing

Bending a flange without relief notches tears material at the bend intersection and creates burrs that require secondary trimming.

Fix: Add bend relief notches (width = material thickness + 0.2mm) at every flange-to-body intersection.

5. Ignoring Grain Direction on Deep Draws

Deep drawing across the rolling grain causes tearing and uneven wall thickness; drawing along the grain produces smooth, consistent shells.

Fix: Specify grain direction on drawing notes. Align blank orientation with draw axis for cylindrical parts.

Frequently Asked Questions

What materials can you stamp?

We stamp stainless steel (304, 316, 430), carbon steel (SPCC, SPHC), spring steel (SK5, SK7), aluminum (5052, 6061, 1100), copper (C110) and brass (C360). Specialty alloys like beryllium copper and phosphor bronze are available upon request for electrical applications.

What is the minimum order quantity?

Standard MOQ is 100 pieces for bending/forming jobs without dedicated tooling. Progressive die orders typically start at 3,000–5,000 pieces to amortize the die investment. Prototype tooling (soft dies) supports 100–500 pieces at moderate cost.

Do you provide tooling design?

Yes. Our in-house die design team creates progressive die layouts, deep-draw tooling and single-hit dies. Die design cost is included in the tooling quotation. We also review customer-supplied die designs for manufacturability before fabrication.

What tolerance can you achieve?

Standard stamping tolerance is ±0.05 mm on critical dimensions. Precision stamping (fine-blanking) achieves ±0.02 mm. General dimensions follow ±0.1 mm at no additional cost. Tighter tolerances increase die complexity and should only be specified on mating/functional surfaces.

Can you support prototype tooling?

Yes. For volumes under 500 pieces, we offer soft-tooling (machined dies without hardened inserts) at 40–60% of full die cost. Soft dies produce accurate samples for fit testing and functional validation before committing to production tooling.

What is the tooling lead time?

Single-hit dies: 7–10 days. Progressive dies: 12–18 days. Deep-draw tooling: 10–15 days. Complex multi-station progressive dies with in-die sensing: 18–25 days. Prototype soft tooling: 5–7 days.

Do you provide surface treatment?

We offer passivation (SS), zinc plating, nickel plating, chrome plating, tin plating (copper/brass contacts), anodizing (aluminum), powder coating, painting and electrophoretic deposition (e-coating). Plating specifications can be matched to ASTM, ISO or customer-specific standards.

Can you manufacture according to our drawings?

Yes. We produce parts from STEP 3D models, DWG/DXF 2D drawings, or dimensioned PDF prints. Our engineering team reviews every drawing for DFM compliance before tooling begins, and returns a detailed report with any recommended modifications.
