Billet Preparation

Billet Preparation

The production process begins with the careful selection of high-quality aluminum billets, which are the raw material for extrusion. These billets are typically made from pure aluminum or custom alloys, depending on the required mechanical properties and application.

  • Material Selection: Choose from 6063, 6061, 6005, and other alloys to meet specific strength, corrosion resistance, and formability needs.
  • Preheating: Billets are preheated to 400–500°C to improve plasticity and ensure a uniform extrusion process, reducing the risk of defects.
  • Quality Control: Each billet undergoes strict inspection for chemical composition, surface quality, and internal structure to guarantee consistent performance.

Proper billet preparation is essential for achieving precise dimensions and high surface quality in the final extruded profiles.

Extrusion

The preheated billet is loaded into the extrusion press, where it is forced through a specially designed die under high pressure. This process shapes the aluminum into the desired cross-sectional profile.

  • Die Design: Custom dies are engineered to create complex shapes, including hollow, solid, and multi-void profiles.
  • Direct & Indirect Extrusion: Both methods are used to optimize material flow and surface finish for different applications.
  • Quenching: Immediately after extrusion, profiles are rapidly cooled (air or water quenching) to lock in mechanical properties.
  • Stretching: Profiles are stretched to correct any twisting or warping, ensuring straightness and dimensional accuracy.

Advanced extrusion technology enables the production of lightweight, strong, and highly customized aluminum profiles for a wide range of industries.

Extrusion Process
Surface Treatment

Surface Treatment

After extrusion, aluminum profiles undergo various surface treatments to enhance appearance, durability, and corrosion resistance.

  • Anodizing: Forms a protective oxide layer, available in a range of colors, improving wear and corrosion resistance.
  • Powder Coating: Applies a uniform, decorative, and weather-resistant finish in virtually any color.
  • Electrophoresis & Wood Grain: Advanced techniques for premium finishes, including metallic and natural wood effects.
  • Polishing & Brushing: Mechanical treatments to achieve glossy or matte textures as required by the application.

Surface treatment not only improves the product’s lifespan but also allows for branding and aesthetic customization.

Precision Machining

The final step involves precision machining and assembly to meet specific customer requirements and ensure ready-to-use components.

  • CNC Machining: High-precision cutting, drilling, and milling for complex geometries and tight tolerances.
  • Punching & Welding: Additional fabrication processes for holes, slots, and joining multiple profiles.
  • Assembly: Integration of fasteners, gaskets, and other components for turnkey solutions.
  • Quality Inspection: Rigorous dimensional and surface checks to ensure every part meets international standards and customer specifications.

Our advanced machining capabilities enable us to deliver fully customized, high-quality aluminum solutions for any industry.
