Extruded Aluminum Services

Pennex is recognized as an expert in custom aluminum extrusions for clients in automotive, building and construction, transportation, consumer durables , and other industries. We offer dedicated service with a fast turnaround time and can meet even the most demanding requirements for dimensional tolerance.

Standard and Customized Aluminum Products

Our standard products include zee, tee, I-beam, rod, bar, hex, pipe, tube, and other extrusion shapes. Products are available in a range of sizes and can be made with 6000 series aluminum along with other custom alloys. Check out our catalog for standard dimensions and detailed specifications.

At Pennex, we realize that every project is different. In order to fabricate custom aluminum products to better meet your requirements, we’ve invested in state-of-the-art extrusion presses, billet heating, quenching, and handling equipment along with enhancing our engineering capabilities. We can produce custom aluminum extrusions with complex multi-void hollow shapes, tight tolerances extruded to your specifications. Additional fabrication and finishing capabilities make us a full-service provider for all your aluminum needs.

Equipment and Capabilities

The Importance of Stock Aluminum Extrusion

Pennex is able to produce aluminum profiles in predetermined shapes, sizes, and thicknesses. Our standard aluminum extrusion process involves using die openings with specific dimensions for your project. One major advantage of working with our company for stock bars, rods, beams, and more is that we can produce these materials quickly and without errors.

We coordinate with you to determine an extrusion die shape suitable for your applications, working with a focus on standards set by the Aluminum Association. We’ll help you select an alloy strong enough for your environment, and you’ll experience minimal wait times prior to production, as our standard die shapes are ready for operation and can be changed out rapidly.

The Need for Custom Shapes

The fabrication of custom aluminum extrusions are in order when the outlines of your project call for an entirely new profile design. Our team makes your vision a reality by using specialized tools for accuracy when creating the extrusion die. Pennex caters to your budget and expectations with custom shapes that promote the following:

• Simple assemblies (cut, drill, or bend aluminum shapes on-site)
• Minimal waste
• Ease of attaching multiple aluminum products together
• High tolerances and tensile strength
• Application of various finishes to aluminum surfaces

Our Aluminum Extrusion Process

The process of creating stock aluminum extrusions and custom shapes begins with a design. This step in the extrusion process is perhaps the most important, as the dimensions of the extrusion die influence the final form. Once our design engineers finalize your aluminum profile shape, Pennex continues with a systematic procedure:

Heating Aluminum Billets

Your aluminum alloy undergoes an intense heating treatment for a soft consistency that is conducive to extrusion. We lubricate the die attachments and use a ram to push the malleable solid through an opening in our machinery. The aluminum alloy then takes on the correct shape.

Cooling the Aluminum Extrusions

Pennex uses precisely calibrated machinery to shear standard and custom shapes to the appropriate length as they exit our extrusion press. Operators then relocate the aluminum to a cooling location where we expose materials to a water and air quenching system.

Extruded Aluminum Stretching

Our professionals remove any imperfections from aluminum extrusions by placing the materials on a stretcher. This process eliminates any bends or twists that might originate during the cooling stage.

Aging and Finishing

Extruded aluminum may be placed in an aging oven for maximum durability and hardness. We place standard and custom shapes in a temperature-controlled environment where a natural oxide coating forms to shield surfaces from the elements.
