Metal Swaging, Cold Drawn Aluminium Tube, Non-Ferrous Tube and Bar Straightening and Tube End Forming.
HAO HAN specialises in cold drawing processes for aluminium tubes. The advantages of this process are primarily reflected in enhanced product performance. This manufacturing technique also improves dimensional accuracy, expands application range, and delivers excellent cost-effectiveness.
In the cold drawing process, both the front-end heading and the back-end straightening stages can be independently adjusted based on the material characteristics and product requirements. This allows precise control over taper, angle, and straightness—providing flexible and efficient processing solutions.
This process is a metalworking technique primarily used to reduce the size of metal tubes and bars, improve dimensional accuracy, and enhance mechanical strength through the use of dies.
This process is used to correct curvature in metal tubes, especially after operations such as extrusion, welding, or cold drawing. The goal is to ensure proper straightness for improved assembly and functionality.
Swaging is a cold working technique used to reduce the diameter of metal tubes and bars by applying rotary force through hammering dies. It is a chipless forming process, meaning no material is removed during reshaping.
The cold drawing process is used to control the outer diameter, inner diameter, and wall thickness with tolerances tighter than ±0.05 mm. A staged reduction design is also employed to achieve smaller diameters or higher precision while minimizing material stress.
In addition to achieving dimensional precision, the process is also capable of transforming round tubes into non-circular profiles such as square, oval, rectangular, or hexagonal shapes. This offers extensive flexibility and adds significant value to the finished materials.
