Stamping Parts Material Thickness Range

Material thickness is a key parameter in stamping part production, dictating press selection, tool design, and part functionality—with typical ranges spanning from ultra-thin foils (0.01mm) to thick plates (25mm), depending on the application. The thickness of the metal sheet directly impacts formability, press force requirements, and the complexity of stamping operations, making it essential to select a thickness that balances manufacturability and part performance.

Ultra-thin materials (0.01mm–0.1mm) are used for precision stamping parts like electronic sensors, microconnectors, or battery foils. These thin sheets (e.g., aluminum foil 1N30, copper foil C1100) require specialized presses with high precision (±0.001mm) and gentle clamping to avoid wrinkling or tearing. For example, stamping a 0.05mm thick copper foil into a microconnector requires a servo-driven press with low force (5–10 tons) and a die with micro-sized features, ensuring the part retains dimensional accuracy.

Medium-thickness materials (0.1mm–3mm) are the most common in stamping, used for parts like automotive trim, appliance panels, and electrical enclosures. Materials in this range (e.g., cold-rolled steel 1008, aluminum 3003-H14) balance formability and strength, compatible with standard turret punch presses or mechanical presses (10–50 tons). For instance, a 1mm thick aluminum sheet can be easily punched, bent, and formed into a washing machine control panel, requiring minimal tool adjustments and standard lubrication.

Thick materials (3mm–25mm) are reserved for heavy-duty stamping parts like structural brackets, construction hardware, or industrial valves. These thick sheets (e.g., hot-rolled steel A36, stainless steel 316L) require high-force hydraulic presses (50–500 tons) and robust tooling (e.g., thick carbide dies) to punch or shear. For example, stamping a 10mm thick A36 steel bracket needs a 200-ton press to generate enough force for blanking, and the die must have reinforced edges to withstand pressure.

Beyond the standard range, specialized stamping can handle thicker materials (up to 50mm) for extreme applications like mining equipment components, but this requires custom presses and multi-step processes (e.g., pre-punching, heat treatment). Material thickness also affects post-stamping processes: thin parts may need annealing to relieve stress, while thick parts may require grinding to smooth edges. By selecting the appropriate material thickness based on part design, application, and available equipment, manufacturers can ensure efficient stamping and a final product that meets structural and functional requirements.
