Common materials include steel, stainless steel, zinc alloy, and engineering plastics. Steel snap-on panels are often electroplated or powder-coated after stamping to enhance rust resistance (e.g., galvanizing, chrome plating). Stainless steel snap-on panels are more suitable for high humidity or corrosive environments.
Stamping processes ensure dimensional accuracy (e.g., tolerance ±0.1mm). Complex structures may combine welding or riveting processes.
