MetalStamping

Producing high-quality stamped metal components at scale — from progressive die stamping and deep drawing to fine blanking for automotive, electronics, and appliance industries.

Metal stamping process at GM Industries

Precision at High Volume

Metal stamping transforms flat sheet metal into finished components through a series of forming operations including blanking, bending, piercing, drawing, and coining. The process delivers exceptional repeatability and tight tolerances at production volumes ranging from prototypes to millions of parts.

GM Industries offers progressive die stamping for complex multi-station parts, deep draw stamping for cup-shaped and enclosed components, and fine blanking for parts requiring smooth, shear-free edges and flatness that conventional stamping cannot achieve.

⚙️
Progressive Die Stamping
Sheet metal is fed through a series of stations in a single die, each performing a different operation. Produces complex parts at high speed with consistent quality and minimal material waste.
💧
Deep Draw Stamping
Creates cup-shaped or box-shaped parts by drawing sheet metal into a die cavity. Used for enclosures, housings, cans, and components where depth exceeds diameter.
🔬
Fine Blanking
A precision stamping process that produces parts with smooth, burr-free edges and superior flatness. Eliminates secondary machining for gears, cam plates, and safety-critical components.
How It Works

The Metal Stamping Process

From die engineering to finished parts, each step is optimized for precision, speed, and material efficiency.

01
Die Design
Engineers design the stamping die using CAD/CAM, simulating material flow, springback, and forming forces to ensure first-article accuracy.
02
Material Feeding
Coil stock or sheet blanks are loaded into automatic feeders that precisely position the material for each press stroke with consistent registration.
03
Stamping
The press cycles through blanking, piercing, bending, and forming operations at high speed, shaping the flat stock into the final component geometry.
04
Trimming
Excess material, slugs, and carrier strips are removed. Parts are separated from the strip and flash or burrs are trimmed for clean edges.
05
Finishing
Parts undergo deburring, plating, powder coating, or other surface treatments as required, followed by dimensional inspection and packaging.
