What types of parts are most commonly produced by custom metal stamping services?

Quick Answer

Metal stamping produces thousands of different parts across virtually every industry. Common examples: automotive body panels, brackets, and chassis components; electrical connectors, terminals, and contacts; appliance panels and brackets; industrial washers, shims, and gaskets; electronic EMI/RFI shielding cans; spring clips and retaining rings; heat sink fins for electronics cooling; nameplates and data tags; fasteners and hardware; and food container lids and closures.

Automotive Stamped Parts

The automotive industry is the largest consumer of metal stampings. Common parts: body panels (doors, hoods, fenders), structural brackets (engine mounts, suspension brackets), chassis components (crossmembers, reinforcement plates), heat shields, brake backing plates, seat tracks and brackets, fuel tank straps, and exhaust hangers. Automotive stampings range from thin (0.5mm) decorative trim to thick (6mm) structural brackets.

Electrical and Electronic Stamped Parts

Precision stamping produces critical electrical components: connector pins and sockets (brass, phosphor bronze), electrical terminals (tin-plated copper), relay and switch components, EMI/RFI shielding cans (steel, tin-plated steel), heat sink fins (aluminum), battery contacts (stainless steel), and lead frames for semiconductor packaging. These parts require precision tolerances of ±0.001" or better.

Consumer and Industrial Products

Appliance components: washing machine panels, dryer drums, refrigerator shelves, oven brackets. Hardware: washers (flat, lock, spring), retaining rings, shims, gaskets, nameplates, and serial number tags. Food packaging: can lids, bottle caps, pull tabs, and foil seals. Construction: metal ties, brackets, joist hangers, and flashing. Agricultural: equipment guards, panels, and brackets.

Why Choose SOMI Custom Parts

At SOMI Custom Parts, our metal stamping services cover parts from simple washers to complex progressive die components with 15+ stations. We work with all standard stamping materials: cold rolled steel, galvanized steel, stainless steel, aluminum, brass, copper, and spring steel. Our engineers design the progressive die layout to maximize material utilization and minimize waste. We also offer secondary operations: tapping, welding, and surface finishing.

Case Study

A manufacturer of electrical enclosures needed 100,000 stainless steel EMI shielding cans per year. The design required precise .050" x .200" vents in a grid pattern, 90-degree flanges, and two M3 tapped holes. SOMI designed an 11-station progressive die that pierced the vent pattern, formed the flanges, and cut the blank to final shape. Each press stroke produced a complete part at 80 pieces per minute. Tapping was done in a secondary automated operation.

Industry Data

The precision metal stamping industry produces over 500 billion parts annually worldwide (Precision Metalforming Association, 2025). Automotive accounts for 60% of stamping output by value, electronics 15%, appliances 10%, and industrial 10%. The average progressive stamping die produces 3-5 million parts over its lifetime before requiring replacement.
