Sheet metal fabrication is a cold working technology for thin metal sheets. The complete production flow consists of laser cutting, punching, CNC bending, welding, deburring, surface finishing and assembly.Common raw materials include cold rolled steel, galvanized steel, stainless steel and aluminum alloy. Different materials match different usage scenarios: galvanized steel for outdoor anti-rust cabinets, stainless steel for medical and sanitary equipment, aluminum alloy for lightweight new energy housings.

CNC bending and laser welding are core processes for precision products. High-end sheet metal parts for medical devices and energy storage equipment require a dimensional tolerance within ±0.1 mm.For surface finishing, environmental powder coating has replaced traditional paint spraying due to superior anti-corrosion performance and environmental compliance, becoming the standard process for export orders.

Modern sheet metal workshops adopt robotic welding, automatic bending lines and AI visual inspection to realize intelligent production, reduce manual errors and stabilize product quality. Integrated full-process production (cutting, bending, welding and coating in one factory) is the mainstream development direction of qualified sheet metal manufacturers.
