Aluminum Extrusion

Consistent Quality

Shorter Lead Times 

Consistent Quality, Shorter Lead Times & Greater Capabilities for Custom Aluminum Extrusions

With the best people, processes, and machinery, we produce tighter dimensional tolerances, consistent quality, and better finishes for even the most complex extruded aluminum shapes. State-of-the-art aluminum extrusion press and quench systems enable us to meet the most demanding industry requirements, while achieving higher production volumes.

 

With turnaround times as short as one week, Momentum Manufacturing Group can deliver your custom aluminum extrusion profiles and manufactured products in a fraction of the time of most other aluminum extruders.

 

Whether you need a custom heat sink, t-slot or one-of-a-kind extruded shape, outsourcing of crucial parts, or to launch a new product line; our manufacturing team can help you save time and money every step of the way. From design for manufacturing (DFM) support to aluminum fabrication and CNC machining to parts assembly, packaging, and fulfillment solutions, we strive to help our customers improve their manufacturing process and bottom line.

Our Extrusion Process

Working with Momentum Manufacturing Group is a collaborative process. Our comprehensive set of capabilities ensures you get a customized and personal approach from our team. Following the initial aluminum profile design review, we work with your product development engineers to develop a desired aluminum profile that meets their finished product requirements. Once the aluminum profile design has been approved, the aluminum extrusion die is manufactured. An advantage of the aluminum extrusion process over other metal production processes, such as casting, is that custom engineered aluminum extrusion dies can be made in a fraction of the time.

 

Extruding the Aluminum Profile

With the final profile design approved and the die prepared, the billet and extrusion tools are preheated to ready them for the aluminum extrusion process. The billet is transferred to the cradle and then crushed against the die, becoming shorter and wider until it has full contact with the container walls.

Quenching (Cooling) the Profile

Once the fully formed profile has been extruded, depending on the alloy, the profile is cooled by a state-of-the-art Presezzi HECS high velocity, multi-sided air and water quench system that puts out over 600 gallons per minute of water at nearly 130 lbs. per square inch. Faster cooling preserves the extrusion profile characteristics, mechanical properties, and tolerances and ensures even and distortion-free cooling of any extrusion shape. 

Stretching, Cutting & Aging

A “stretcher” is employed after the profile has been quenched (cooled) to straighten the extrusion and correct any twist that may have occurred. The stretcher is also used to impart cold work to the extrusion. Conveyors then feed the profile to the saw to be cut to pre-specified lengths. Production of short lengths, miter cuts, or tight tolerances is performed with a secondary cutting operation. Depending on the aluminum alloy used, aging, or age-hardening, may be needed to obtain maximum strength, hardness, and elasticity.

Aluminum Surface Finishing

As soon as unfinished aluminum is exposed to the atmosphere, a protective oxide coating naturally begins to form. For certain applications, aluminum profiles require no more protection than this thin, transparent oxide film. If an additional surface protection or enhanced finish, such as Kynar paint, powder coat, or anodizing, is desired, Momentum has established partnerships with several firms who specialize in many types of extrusion finishes.

Fabrication, CNC Machining and Component Packaging

After sufficient aging, the aluminum profiles maybe moved to other areas of our plant for further fabrication and machining, or are packed and prepared for shipment. Profiles are packaged to ensure they are protected from surface damage, twisting or other transit, handling, and storage hazards. Customers may specify their packaging requirements, or the type of extruded product may suggest a particular method of packaging for ease of storage or delivery.
