Custom Aluminum Extrusion Services
The aluminum extrusion service can efficiently produce lightweight, high-strength, corrosion-resistant aluminum profiles. Combined with our CNC machining, it provides a highly cost-effective solution for small batch production of custom extrusions.
What is Aluminum Extrusion?
The aluminum extrusion process is to heat the aluminum to a malleable state, usually between 350 and 500 Celsius degrees, depending on the alloy type. The heated aluminum billet is then placed in a chamber and high pressure is applied using a hydraulic press, forcing the aluminum through a specially designed mold, which determines the final shape of the extrusion. As the material exits the mold, it will cool and solidify to maintain the required shape. The extruded aluminum can be further machined, such as cut, CNC machined or polished to meet specific application requirements. This process is highly efficient and can produce complex shapes with excellent precision and surface quality, making aluminum extrusion ideal for the mass production of structural parts, frames, housings, radiators and other parts.
FastPreci Aluminum Extrusion Types
At FastPreci, we offer versatile aluminum extrusion capabilities tailored to a wide range of profile shapes — whether standard or highly customized. All of these profile types can be manufactured using hot extrusion, cold extrusion, or warm extrusion methods depending on material properties and dimensional requirements. From raw extrusion to final CNC precision machining, FastPreci delivers a truly one-stop service that ensures your parts are accurate, ready-to-assemble, and production-ready.
Solid Profiles
Solid extrusions feature a continuous cross-section without internal cavities, offering excellent strength and structural integrity. They are ideal for simple structural components, brackets, and rails that require rigidity and ease of post-processing.
Hollow Profiles
Hollow extrusions include one or more enclosed voids within the cross-section. These are widely used for applications requiring reduced weight, internal cable routing, or thermal management — such as tubing, frames, and enclosures.
Complex Profiles
When your design calls for intricate geometries, asymmetric shapes, or multiple functional zones in a single profile, our engineers work closely with you to create precise custom dies. These profiles are especially suitable for integrated components that minimize assembly steps.
Advantages of Aluminum Extrusion
Lightweight Yet Strong
Aluminum extrusions offer an exceptional strength-to-weight ratio, making them ideal for applications that require both durability and reduced mass—such as aerospace frames, electronic housings, and automation components.
Design Flexibility
The extrusion process enables the creation of complex cross-sectional shapes that would be difficult or costly with other manufacturing methods. Custom profiles can integrate multiple functions into a single part.
Excellent Corrosion Resistance
Aluminum naturally forms a protective oxide layer, and with surface treatments like anodizing, extruded parts gain even greater resistance to corrosion—ideal for outdoor or high-humidity environments.
Cost-Effective for Medium to High Volume
Once the extrusion die is made, the per-part cost becomes very competitive, especially for medium and large production runs. It reduces the need for secondary operations and material waste.
Easy to Machine, Cut, and Join
Extruded aluminum profiles are highly machinable and can be easily drilled, milled, tapped, or welded. This makes them well-suited for integration with CNC finishing and fast assembly.
Sustainable and Recyclable
Aluminum is 100% recyclable without loss of quality. Using recycled material not only lowers costs but also supports sustainable manufacturing practices.

Aluminum Extrusion Surface Finishing Options
The above treatments can be used individually or in combination (e.g. sandblasting + anodizing) to meet both functional and aesthetic requirements. The choice of surface treatment is often based on the application (e.g. outdoor/indoor), the desired appearance (glossy/matte/tinted) and the budget/batch size.
| Finishing Option | Process Description | Typical Applications / Benefits |
| Anodizing | Electrochemical process that forms a protective oxide layer on the aluminum surface. | Corrosion resistance, improved surface hardness, color options (black, silver, etc.) |
| Powder Coating | Dry powder is electrostatically applied and cured under heat to form a durable coating. | Decorative finish, enhanced durability, wide color selection, UV resistance |
| Painting | Wet paint is sprayed or brushed onto the surface and air/oven cured. | Lower setup cost for small batches, color flexibility, indoor-use applications |
| Polishing | Mechanical or chemical method to smooth and brighten the surface. | Decorative parts, reflective surfaces, cosmetic appeal |
| Brushing | Surface is abraded using fine belts to create a linear texture. | Modern aesthetic, fingerprint resistance, often used in appliances and enclosures |
| Sandblasting | Abrasive blasting to create a matte or textured finish. | Pre-treatment for anodizing or painting, anti-glare surfaces |
| Electrophoresis Coating | Electro-deposition of paint onto metal surface. | Uniform coating, good corrosion resistance, often combined with anodizing |
| Chromate | Surface treated chemically for adhesion and corrosion resistance. | Primer for paint, electrical conductivity retention, aerospace or electronics |
| Hard Anodizing | A thicker, harder anodized layer compared to standard anodizing. | High-wear applications, mechanical parts, industrial environments |
