How are lean tube connectors produced?

How are lean tube connectors produced? The production process of lean tube connectors mainly includes the following key steps, which may vary depending on different material types (such as aluminum alloy, composite tubes, etc.):

1. General production process
1. Die-casting molding
After melting, aluminum ingots are molded through a die-casting machine to form joint blanks (aluminum alloy joints). Composite pipe joints are made of cold-rolled steel material and are surface-treated with chromium plating.

2. Surface treatment
Shot blasting: remove burrs and improve surface finish.
· Anodizing (aluminum alloy): enhances corrosion resistance.
3. Assembly and quality inspection
Assemble components (such as screws and movable parts) manually or automatically, and ensure dimensional accuracy and functional integrity through multiple quality inspections.

II. Material Differences
· Aluminum alloy connector (third generation): Utilizing anodizing process, it features convenient assembly and disassembly, as well as a high-end appearance.
Composite pipe connector (first generation): It is necessary to choose a design with thread pattern to enhance the friction with the pipe material.

III. Supporting production requirements
The production of connectors needs to match the specifications of lean tubes, such as composite tubes with a standard diameter of 28mm and a wall thickness ranging from 0.8mm to 1.5mm, as well as dedicated connector designs for different generations.
