The Hydraulic Rivetless Riveting Machine is a metal joining device that dispenses with traditional rivets. Driven by hydraulics, it uses molds to apply pressure on two or more layers of metal sheets, causing local plastic deformation of the sheets to form a snap-fit structure for firm connection. It offers high joining efficiency, good sealing performance, and no risk of rivet falling off. It is suitable for materials like cold-rolled steel sheets, aluminum alloys, and galvanized sheets (with a thickness of 0.5-6mm), and widely used in fields such as auto parts, home appliance manufacturing, and hardware accessories. Additionally, it features easy operation and low later maintenance costs.

A handheld fiber laser welding machine is a portable, high-efficiency welding equipment designed for metal processing. It uses a high-energy fiber laser beam to form a molten pool on the workpiece surface, achieving fast and strong welding joints. Widely used in HVAC duct manufacturing, sheet metal fabrication, kitchenware production, auto parts processing, and hardware manufacturing, it supports welding of stainless steel, carbon steel, galvanized steel, aluminum alloy, and other materials. Compared with traditional argon arc welding, it features beautiful weld seams, minimal thermal deformation, high welding efficiency, and low post-processing requirements, significantly improving production efficiency and reducing labor costs.

The TDC Flange Machine is specialized equipment for processing TDC flanges.
