Core Technological Advantages

Intelligent Pipe Bending Process

• Utilizes a fully closed-loop CNC pipe bending system to achieve precision forming of round pipes, square pipes, elliptical pipes, and special profiles, with bending accuracy up to ±0.1°.
• Supports various processes, including push bending, roll bending, and 3D spatial composite bending, capable of processing pipe fittings with diameters ranging from 5mm to 200mm, meeting diversified needs from miniature precision components to large structural parts.

Full-Process Deep Processing Capabilities

• Equipped with multi-station linkage production lines, offering one-stop services for processes such as drilling (accuracy ±0.02mm), laser punching, hydraulic swaging, tube forming, and argon arc welding.
• Achieves integrated processing of pipe fittings' functions, reducing customers' supply chain management costs.
