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...

Powder coating: eco-friendly, wear-resistant and anti-corrosive, preferred for exported energy storage and automation cabinets. Wire drawing & passivation are used for exposed stainless steel housings. Anodizing is exclusive for aluminum parts for wear resistance and coloring. Paint spraying is...

Welding includes spot welding, argon arc welding and fiber laser welding (for high-precision parts with minimal deformation). Rivet pressing uses pressed nuts and studs for internal assembly. Clinching and clamping assembly require no welding.

CNC Bending: Press brakes and dedicated bending dies bend flat plates into cabinets and folded structures; precision bending tolerance can reach ±0.1 mm.

Punching & Grooving: CNC punches create mounting holes, heat dissipation holes and wiring grooves for subsequent assembly.

Cutting: Main methods include fiber laser cutting, CNC shearing and CNC punching. High-power laser cutting features high precision and arbitrary profiling, which is the mainstream cutting method for precision sheet metal.

Sheet metal working refers to comprehensive cold working processes for thin metal plates (generally thickness ≤6 mm), including shearing, punching, bending, welding, riveting, forming and coating, to manufacture metal components such as cabinets, equipment housings and structural brackets. It featur...

High-power fiber laser cutting has been widely adopted. 10,000-watt laser cutting machines have become standard equipment for large manufacturers, delivering smooth burr-free cuts to eliminate manual polishing. Combined with intelligent nesting software, material utilization rises by 10%~18% to cut...
