Aluminium profile frames are widely used in the construction industry due to their strength, durability, and aesthetic appeal. The production process for these profiles involves several critical stages to ensure they meet the required specifications and performance standards.

Material Selection and Billet Preparation

The process begins with selecting high-quality aluminium billets, which are cylindrical blocks of aluminium alloy. These billets are preheated to around 450°C to 500°C, softening the material and making it more malleable for extrusion.

Extrusion

The preheated aluminium billet is placed in an extrusion press, where it is forced through a die to form the desired profile shape. The die is designed to create the specific dimensions and features needed for door frames, including grooves for glass or panels. The extrusion process shapes the aluminium into long profiles that are consistent in size and shape.

Cooling and Stretching

Once the profiles are extruded, they are rapidly cooled using water or air quenching methods. This solidifies the aluminium and stabilizes the shape. After cooling, the profiles are stretched to straighten them and eliminate any internal stresses from the extrusion process, ensuring they are perfectly aligned.

Cutting to Length

The extruded aluminium profiles are then cut into the required lengths based on customer specifications. Precision cutting ensures that each profile fits correctly in the door assembly.

Surface Treatment

Aluminium profiles for doors typically undergo surface treatments such as anodizing or powder coating. Anodizing enhances corrosion resistance, while powder coating provides a smooth, colorful finish that also protects the profiles from wear and weathering.

Quality Control and Packaging

Finally, the profiles undergo strict quality checks to ensure dimensional accuracy, strength, and finish. After passing the quality control process, the aluminum door frame profiles are carefully packaged and ready for delivery.
