Typical Applications of Perforated Aluminum Tube
Manufacturing Process of Perforated Aluminum Tube
The manufacturing of Perforated Aluminum Tubes involves a precise process covering sheet perforation, tube forming, and surface finishing. It ensures hole pattern and dimensional consistency while maintaining tube structural integrity and surface aesthetics. The main process steps are as follows:
Material Selection & Preparation
Aluminum alloys (such as , , , , etc.) are selected based on customer requirements and cut into appropriate sheet sizes or pre-extruded tubes.
For high-precision customization, annealing or pre-flattening treatments may be applied to enhance subsequent perforation accuracy.
Perforation
High-precision CNC perforating equipment (e.g., CNC punch press, turret punch) is used to punch round holes, slots, square holes, diamond holes, and other patterns on the aluminum surface.
Typical open area ranges from 20% to 65%, with minimum hole diameters as small as 0.5 mm.
Hole arrangements can include straight line, staggered, or fish scale layouts based on design requirements.
Flatness, hole positioning tolerance, and edge burrs must be strictly controlled.
Tube Forming
For tubes made from perforated sheets, the material is roll-formed and welded into tube structures.
Common welding methods include TIG welding, laser welding, and seam welding, with welds optionally polished or made seamless.
- Straight seam welding
- Spiral seam welding
Tubes can be formed into round, square, rectangular, oval, or custom cross-sectional shapes.
If using pre-extruded aluminum tubes, perforation is done post-forming (e.g., Perforated aluminum square tubing), often used for telescoping structural supports in thick-walled or high-strength applications, requiring tube punching machines.
Deburring & Shaping
All tubes undergo internal and external deburring and chamfering to ensure safe handling, unblocked flow, and no damage to internal components.
For precision applications, additional processes like roundness correction, straightening, and end-face squaring are performed to ensure dimensional accuracy.
Surface Finishing
To enhance corrosion resistance, weatherability, and visual appeal, Perforated Aluminum Tubes can undergo various surface treatments including anodizing (silver, black, gold, etc.), painting/powder coating, and brushing, polishing, or matte finishing—meeting both functional and decorative needs.
Inspection & Packaging
Every batch of perforated tubes is inspected for appearance, dimensions, and hole pattern accuracy. Strength or corrosion resistance testing is conducted when required.
Finished products are securely packed using anti-scratch films, bubble wrap + woven bags, wooden cases, or steel frames based on transport needs, ensuring delivery quality.
