What is Metal Stamping?

Metal stamping is a high-volume manufacturing process that uses pressurized dies and mechanical or hydraulic presses to transform flat sheet metal or coil strip into precise 3D parts through cutting, forming, and deforming operations. Stamping is the go-to method for producing large quantities of consistent, dimensionally accurate metal components at low per-piece cost.

Common Metal Stamping Methods

• Progressive Die Stamping: Coil strip advances through multiple die stations, each performing one operation (cut, form, pierce). Ideal for high-volume complex parts at 100-800 SPM. Lower per-piece cost above 10,000 units.
• Transfer Die Stamping: Individual blanks transferred between stations by mechanical grippers. Best for large, deep, or heavy parts that cannot use coil feed.
• Deep Drawing Stamping: Draws flat blank into cup or box shape using single-action or double-action press. Produces seamless cylindrical enclosures, cans, and cases.
• Blanking: Cuts a specific 2D flat shape from sheet stock. Basic first operation for most stamping projects.
• Coining: Extreme pressure creates fine detail features like text, logos, or micro-relief patterns.

Key Advantages of Custom Metal Stamping

• Lowest Per-Piece Cost: After tooling amortization, stamping delivers unbeatable unit economics at high volumes
• Ultra-Fast Production: 100-800 parts per minute enables mass production timelines
• Consistent Precision: plus-minus 0.02mm tolerance across millions of parts
• Material Efficiency: Advanced nesting reduces scrap to under 15%
• Complex Geometries: Combine cutting, forming, and embossing in one die

Common Applications of Custom Stamped Metal Parts

Custom metal stamping serves industries including automotive (body brackets, engine components, terminals, shims), electronics (connectors, contacts, EMI shields, heat sinks), appliances (housings, mounting brackets, hardware), hardware (hinges, latches, fasteners), medical devices (surgical instrument components, housings), and industrial equipment (springs, clips, structural parts).

How DeepLink Custom Metal Stamping Service Works

From CAD file upload to high-volume stamped parts delivered worldwide, our custom metal stamping workflow ensures accuracy, tooling investment protection, and full quality traceability.

1. Upload CAD Files and Get Quote

Upload 2D DXF or 3D STEP/STP/SLDPRT files through our secure quote portal with target quantity and lifetime volume estimates. Our engineering team responds within 24 hours with tooling cost, per-piece pricing, and delivery timeline.

2. Free DFM Analysis with Stamping Optimization

Our tooling engineers verify manufacturability, checking blank layout, feed direction, feature strength, spring-back compensation, and material grain orientation. We recommend design adjustments to reduce die complexity and tooling cost.

3. In-House Progressive Die Design and Build

Custom stamping dies designed in UG/AutoCAD and manufactured on our 5-axis CNC and wire EDM machines within 2-6 weeks. Dies undergo tryout with sample parts approved by customer before mass production.

4. High-Speed Stamping Production

Automated coil-fed presses run 100-800 strokes per minute with in-die sensors detecting misfeeds and part defects. Real-time SPC monitoring ensures dimensional consistency across production runs.

5. Quality Inspection and Global Shipping

Sample size inspection with CMM, projection scanner, and profilometer measurement. FAIR/PPAP reports available on request. DDP shipping to 50+ countries via DHL, FedEx, or sea freight for bulk orders.

Available Surface Finishes for Custom Stamped Metal Parts

DeepLink offers comprehensive post-stamping surface finishing services to enhance corrosion resistance, appearance, and electrical performance of your custom stamped metal parts.

Electroplating

Zinc plating (yellow/blue/black passivation), nickel plating, chrome plating, tin plating, silver plating, and gold plating for electrical contacts, connectors, and corrosion protection.

Powder Coating

Electrostatically applied dry powder cured to a durable, uniform finish. Available in 200+ RAL colors, textures (matte, satin, gloss), and specialty finishes for industrial and consumer product parts.

Anodizing (Aluminum)

Type II clear/color anodizing and Type III hard anodizing for aluminum stamped parts requiring wear resistance and decorative color.

Passivation and Deburring

Chemical passivation for stainless steel stamped parts plus mechanical or vibratory deburring to remove sharp edges and stamping burrs, ensuring safe handling and assembly.

Heat Treatment

Case hardening, quenching, tempering, and annealing to achieve target hardness (HRC 30-60) for spring steel, tool steel, and structural stamped components.
