What is Metal Deep Drawing?

Metal deep drawing is a sheet metal forming process where a flat metal blank is radially drawn into a forming die by the mechanical action of a punch, producing a seamless three-dimensional part such as a cup, can, or box. Unlike bending or stamping, deep drawing significantly increases the depth-to-diameter ratio of the part (draw ratio typically 0.5 to 2.5), producing hollow structures that would otherwise require welding or joining.

Common Deep Drawing Methods

• Single-Action Deep Drawing: One punch draws the blank into the die in a single stroke. Ideal for shallow parts with depth less than diameter.
• Double-Action Deep Drawing: Blank holder and punch operate independently, controlling material flow to prevent wrinkling. Used for deeper parts.
• Progressive Deep Drawing: Multiple drawing stations progressively increase depth in stages. Enables draw ratios above 2.0 without material failure.
• Redrawing: Secondary draws on already-drawn parts to further increase depth or reduce diameter.
• Ironing: Reduces wall thickness of drawn part while increasing height. Used for beverage cans and aerosol containers.

Key Advantages of Custom Metal Deep Drawing

• Seamless Construction: No welded joints means better corrosion resistance and structural integrity
• High-Volume Efficiency: Production rates up to 60 parts per minute for automated deep drawing lines
• Excellent Surface Finish: Smooth outer walls suitable for direct decoration without secondary finishing
• Weight Reduction: Thinner walls achievable through ironing without sacrificing strength
• Complex Geometries: Multi-step drawing produces stepped, tapered, and conical shapes impossible with other methods

Common Applications of Custom Deep-Drawn Metal Parts

Custom metal deep drawing serves industries including cookware and kitchenware (pots, pans, sinks), cosmetic packaging (perfume caps, lipstick cases, jars), food and beverage (cans, containers, closures), medical devices (surgical cups, implant housings, device enclosures), aerospace (fuel tanks, structural cups), automotive (oil filters, fuel tank components), and industrial (motor housings, battery enclosures, hydraulic cylinders).

Available Surface Finishes for Custom Deep-Drawn Metal Parts

DeepLink offers comprehensive post-drawing surface finishing services to enhance corrosion resistance, appearance, and functional performance of your custom deep-drawn metal parts.

Electropolishing (Stainless Steel)

Electrochemical process removes surface layer to produce ultra-smooth, mirror-bright finish with enhanced corrosion resistance. Standard for medical, pharmaceutical, and food-grade deep-drawn cups and containers.

Anodizing (Aluminum)

Type II clear/color anodizing (5-25 micrometers) for cosmetic packaging and consumer product cups. Type III hard anodizing for wear-resistant automotive and industrial parts.

Powder Coating

Electrostatically applied dry powder cured to a durable finish. Available in 200+ RAL colors including textured, metallic, and specialty finishes. Ideal for cookware, appliances, and industrial enclosures.

Plating

Nickel plating, chrome plating, zinc plating, and gold plating for decorative and corrosion protection on steel and brass deep-drawn parts.

Passivation and Cleaning

Chemical passivation for stainless steel restores passive chromium oxide layer. Ultrasonic cleaning and vapor degreasing prepare parts for cleanroom or medical assembly.
