Aluminum Extrusion Finishes

Surface finishes protect extruded aluminum parts from corrosion and wear while improving appearance. View XCD's finishing methods listed below. And we're happy to discuss additional options to meet your specific requirements.

Anodizing

Creates a protective oxide layer that stops corrosion and provides electrical insulation. Available in natural, black, and colored finishes for architectural and electronic applications.

Powder Coating

Dry powder coating baked onto aluminum for tough, colorful finish. Resists scratches, UV rays, and chemicals. Wide color range for outdoor and decorative uses.

Electrophoresis

Uniform coating process using electric current to deposit paint evenly on complex shapes. Provides smooth finish and good corrosion protection for automotive parts.

Brushed Finish

Mechanical brushing creates directional grain texture that hides scratches and fingerprints. Popular for consumer electronics, appliances, and architectural trim with metal look.

Bead Blasting

High-pressure glass beads create uniform matte surface texture. Removes machining marks and provides consistent appearance for precision parts and decorative applications.

Painting

Liquid paint application offers unlimited color choices at low cost. Good for prototypes, small batches, and applications where color matching is important.

Silk Screen Printing

Prints logos, text, and graphics directly onto aluminum surfaces. Durable ink bonds well for control panels, nameplates, and branded products.

Laser Engraving

Precise laser removes material to create permanent markings, serial numbers, and detailed patterns. Clean process with sharp edges for identification and decorative work.

Quality Your Can Trust

Quality is built into every step of our aluminum extrusion process. With ISO-certified production facilities and over 70 extrusion and inspection machines, we deliver parts that meet high standards in accuracy and finish.

Dimensional and Tolerance Checks

We measure key dimensions like cross-section width, height, wall thickness, total length, straightness, flatness, perpendicularity, and fit of holes or slots. Inspection tools include calipers, micrometers, height gauges, and coordinate measuring machines (CMM).

Surface Inspection

All profiles are checked for scratches, dents, cracks, air bubbles, burrs, extrusion lines, and deformation. Lighting and magnification are used to spot fine surface issues.

Material and Performance Testing

On request, we provide test results for strength and hardness, as well as RoHS reports and material certificates, depending on project needs.

What's the Aluminum Extrusion Process?

Aluminum extrusion is the process of pushing a heated aluminum billet through a custom die to form profiles with a specific cross-sectional shape. At XCD, we follow a standard, proven production flow:

It begins with die machining, solid, hollow, or semi-hollow, and billet preheating, typically 400–500°C. Aluminum is then extruded—either direct or indirect, hot or cold—depending on the aluminum alloys and end use.

Once extrusion, the profile is cooled, stretched, and cut to size. Additional steps such as aging for strength and hardness, surface finishing for appearance and functionality, or assembly can be applied as needed. Each custom aluminum extrusion goes through inspection and packaging before delivery.

Applications of Aluminum Extrusion

Industries rely on custom aluminum extrusions for their strength-to-weight ratio and design flexibility. Below are some of the most common applications.

Industrial

Machine frames, workstations, and automation systems.

Transportation

Auto frames, trailers, and train body components.

Construction

Doors, windows, curtain walls, handrails, and facades.

Energy

Solar frames, wind turbine parts, and offshore structures.

Electronics

Enclosures, LED housings, and heat sinks.

CNC machining is renowned for its ability to achieve high precision and tight tolerances, essential for complex and detailed parts. Typically, standard CNC machining can maintain tolerances within ±0.01 inches (±0.127 mm). XCD defaults to standardized tolerances without special requirements. For even more precise requirements, advanced CNC machines can achieve tolerances as tight as ±0.0005 inches (±0.0127 mm) under optimal conditions. The achievable tolerance depends on several factors including the material, part geometry, size, and the specific type of CNC machine used. This capability makes CNC machining a preferred choice for industries that require highly accurate components, such as aerospace, medical, and automotive sectors.
Manufacturing Process: 3D printing is an additive process, building parts layer by layer from materials like plastic or metal. In contrast, CNC machining is subtractive, cutting away material from a solid block to shape the final product. Material Efficiency: 3D printing minimizes waste by using only the material needed to form the part, whereas CNC machining can produce more waste due to its subtractive nature. Speed and Cost: For small batches and complex geometries, 3D printing can be faster and more cost-effective. CNC machining is preferable for larger volumes and materials requiring high precision and strength. Surface Finish and Tolerances: CNC machining typically achieves better surface finishes and tighter tolerances compared to 3D printing.
John T. Parsons is often credited as the father of CNC machining. In the late 1940s, Parsons developed the first numerical control techniques and applied them to the production of helicopter rotor blades. Working alongside engineer Frank L. Stulen, Parsons conceptualized the method of using punched tape to guide machine tools. This innovation laid the groundwork for the development of CNC (Computer Numerical Control) technology. Their pioneering work eventually led to the creation of the first CNC machines in the 1950s, which revolutionized manufacturing by improving the precision, efficiency, and repeatability of machining processes.
A machining center is a highly advanced CNC machine designed to handle a variety of machining tasks including milling, drilling, and tapping, all within a single setup. This integration enhances efficiency and accuracy by reducing the need to transfer parts between different machines. Machining centers are equipped with a tool turret or magazine that holds multiple tool options, enabling automatic tool changing under CNC control. This capability allows for rapid switching between operations, optimizing production flow. Typically, machining centers are used for complex parts that require precision machining from multiple angles, making them indispensable in modern manufacturing environments.
