5 Must-Have Features in a Aluminum Extrusion CNC

The biggest misconception about utilising extrusions within a design, is that the designer is limited to the standard profiles offered by the manufacturer. Custom production-ready tooling is surprisingly cheap, only costing a fraction of injection mould tools, yet still offering control over your design intent. Compared to processes like injection moulding, with large upfront investment, this can be a way to reduce your per-unit cost and overall investment when exploring new product development.

When designing the Visitor Rego Kiosk, the extrusion design was the first part to be signed off and sent for production. The first off-tool samples were used to produce a functioning prototype, while the remainder of the parts were being fabricated from sheet metal and plastic. This allowed flexibility to continue to refine the design as required without the need to modify the extrusion design. This takes careful planning and consideration, however if done properly can save a large amount of time and costs, getting your product to market faster as well as adding an element of completion and final function to the prototypes, which could be hard to achieve with other manufacturing processes.

Aluminum extrusions are versatile, finding use in a wide range of industries and applications. But that diversity of applications also means your supplier&#;s inventory of standard profiles won&#;t cover every need.

Many product designers encounter unique situations. You might need non-standard shapes, specialized finishes, or uncommon alloys. So creating custom aluminum extrusions makes the most sense.

If you want to create custom extruded profiles, you must be aware of the most essential design considerations. This article lists our top five extrusion design tips to set you on the right path. These tips will help you avoid quality issues and manage costs when producing custom extrusions.

Tip #1 &#; Choose the Right Alloy for Your Application

Materials databases list an impressive number of aluminum alloys for designers. It&#;s easy to get caught up in choosing the one that provides the best physical properties for your application. But you should also carefully consider the impact of extrudability.

Choosing one of the more popular aluminum extrusion alloys can improve extrusion characteristics. Doing so can also minimize defects and lower production costs.

These alloys may have lower strength, hardness, or wear resistance than some alternatives. However, there are still ways to fine-tune the aluminum&#;s properties after extrusion. Heat treatments and tempering can help you get the best qualities for easy manufacturing and improved durability.

Tip #2 &#; Select the Most Appropriate Surface Finish

Another great way to improve the performance of custom extruded aluminum products is to apply surface finishes. There are several common types of aluminum finishes, each offering different benefits.

Finishing can improve the durability or aesthetics of your custom extrusions &#; and some finishes can even do both!

For example, anodizing your aluminum extrusions can improve corrosion and wear resistance. At the same time, it allows you to dye the aluminum in various metallic colors.

Getting good value for your money is essential to a project&#;s success. That&#;s why it&#;s invaluable to understand the different factors that affect the cost of custom extrusions.

The costs to produce custom aluminum extrusions are strongly affected by various factors:

• Type of aluminum alloy used
• Size and complexity of the custom extrusion die (sometimes tooling costs are refunded with high volumes)
• Current cost of aluminum
• Local labor costs
• International shipping rates
• Discounts for larger production volumes (or markups for smaller batches)
• Additional time and specialized equipment needed for temper treatments or surface finishes

Understanding how and why different elements affect the price of custom aluminum extrusions is vital. This way, you can make better decisions and get the best value.

Tip #4 &#; Learn About Extrusion Joining Methods

Including joints in your custom extrusion design can be surprisingly helpful. Sometimes, a single aluminum profile can be too large, asymmetric, or complex. In these cases, joining multiple extrusions together makes manufacturing easier and cheaper.

Extrusion joining methods can also improve the modularity of your product. They increase its customizability during use and make handling during installation more manageable.

There is even the option to use specialized hinge joints that allow for limited rotation at the joint. Doing so adds flexibility to assemblies.

It&#;s valuable to know the different extrusion joining methods. They can improve the versatility of your custom aluminum extrusion profiles. Choosing the most suitable joining method can also reduce manufacturing costs.

The value of efficient manufacturing is obvious: lower production costs and improved product quality. But how do you optimize your design to capture these benefits?

There are many avenues to optimizing the aluminum extrusion process. Choosing formable alloys, designing the profile to distribute stresses evenly, and using modeling software are great ways.

There is much to understand about designing custom aluminum extrusions, so we naturally can&#;t cover everything here. To learn more, check out our aluminum extrusion design guide, which we&#;ve packed with helpful information for designers.

It&#;s also essential to involve your extruder in the process as early as possible. This way, you can get the perspective of manufacturing engineers with relevant experience.
