Processing Technology

Processing Processes

Stamping, Polishing

High-speed stamping through molds for mass production of hardware parts and enclosures, supporting complex shapes and embossed textures. Cold/hot stamping adapts to different material properties. After welding, the surface must be sanded again; edges should be smooth without weld spatter, burrs, etc., and seams should be flat and smooth.

Cutting Technology

Uses laser cutting, plasma cutting, or water jet cutting technology for precise metal sheet separation, suitable for complex shapes and high precision requirements, with a wide range of material thicknesses and smooth edges.

Sheet Metal Bending

Utilizes CNC bending machines with custom molds to apply force to thin metal sheets, forming various geometric shapes like U, V, or channel shapes. Metal thickness can vary.

Welding

Offers TIG/MIG welding, arc welding, and robotic automation for seamless connections of materials like stainless steel and aluminum, ensuring high weld strength.

Punching

Rapidly completes round, square, and other shaped hole processing using CNC punching machines, supporting batch customization with high precision and cost efficiency.

Riveting

Uses press riveting or pull riveting to connect metal parts without high-temperature welding, preserving surface coatings, suitable for chassis and cabinet assembly, strong and easy to disassemble.
