Aluminum Extrusion


What is Aluminum Extrusion?

Aluminum extrusion is a process that involves shaping aluminum alloy into specific cross-sectional profiles using a heated billet pushed through a die. The die acts as a mold, determining the final shape and dimensions of the extruded aluminum. This process allows for the creation of consistent, durable, and lightweight profiles with excellent strength-to-weight ratios.

Features of Aluminum Extrusion Profiles

1. Primary extrusion: The aluminum ingot is passed through a large extrusion die to form a standard profile section.

2、Precision secondary processing: Cutting, CNC machining, surface treatment, etc. are carried out on the extruded profiles to produce the final parts.

3、Full process autonomous control: Starting from the procurement of standard extruded profiles, we can efficiently complete the entire process of "precision sawing → CNC deep processing (milling/drilling/tapping) → deburring → surface treatment (sandblasting/anodizing) → assembly inspection" in our 12000 square meter base. This ensures quality consistency, controllable delivery time, and optimized cost, and customers only need to connect with us to obtain complete components.

4、Beyond simple cutting: Dozens of CNC machines enable you to perform complex 3D precision machining on standard profiles. For example, precise machining of installation holes, heat dissipation teeth, guide rail slots, irregular interfaces, etc. on aluminum profile frames cannot be achieved by simple extrusion.

5、The standardization of CNC: programming ensures that the machining accuracy (such as position tolerance ± 0.05mm) of thousands of profile parts is completely consistent, meeting the assembly requirements of high-end equipment.

6、Process innovation to solve pain points: Proficient in handling process difficulties such as deformation control, thin-walled machining vibration, and long workpiece clamping in profile processing, ensuring good product yield.

Available Surface Treatment Process For Your Projects

  • Anodizing: The oxidation film thickness: 8-25um with excellent corrosion and wear resistance, making the product more durable and long-lasting.
  • Powder Coating: Film thickness 60-120um.This treatment method forms a dense coating layer with excellent corrosion resistance and aging resistance.
  • Electrophoresis Painting: This treatment method can provide a smooth and glossy surface while maintaining good corrosion resistance on the basis of anodizing treatment.
  • Sand Blasting: This treatment method cleans and roughens the surface of aluminum profiles through the impact of high-speed sand flow, reducing surface roughness and making it brighter and smoother.
  • Brushed: According to the decorative needs of aluminum material surfaces, several brushed effects such as straight grain, random grain, spiral grain, corrugated grain, and swirl grain can be produced.
  • Wood Grain: Wood grain treated with heat transfer printing technology is highly durable, ensuring longevity and quality under normal use. It is a special surface effective.

FAQ

We have industry-leading large-scale manufacturing capabilities. The company is equipped with dozens of imported and domestically produced high-end CNC machining centers, with a team of dozens of experienced professional engineers, and is located in a modern production base of 12000 square meters. This ensures that we can simultaneously carry out multiple large-scale projects, achieving seamless transition from rapid prototyping to million level mass production, fully capable of serving as your reliable strategic capacity backup.

We are positioned as an "engineering solution partner" rather than simply processing incoming materials. Our team of dozens of professional engineers can intervene in early stages (DFM) to provide key recommendations such as material selection, structural lightweighting, heat dissipation optimization, tolerance analysis, and assembly improvement, helping you optimize designs, reduce costs, and accelerate product launch.

This is our core expertise. We ensure through the following combination punches: Process assurance: Adopting multi axis precision machining to ensure that the flatness and roughness of the sealing surface meet extremely high requirements (such as flatness ≤ 0.1mm/total length). Process control: Achieve full process independent control within a 10000 square meter base, from processing to cleaning and testing, to eliminate quality risks caused by outsourcing.
