Getec Aluminum Extrusion Design Saves Time and Money

In addition, Getec Industrial fabricates all of our extrusion dies for our customers on site. Unlike other aluminum extrusion companies, there is no waiting while shipping it to the die manufacturer, waiting for them to machine it and ship it back.

This also allows us to make changes to your die if the initial run doesn’t meet your expectations without the lag time of shipping it back and forth to the die manufacturer for rework. Giving you the ability to produce a better aluminum extrusion product in a fraction of the time it would take for one of our competitors.

Lightweight Aluminum Tubing

Getec Industrial is a global supplier of an extensive line of seamless and extruded aluminum tubing with a variety of wall thicknesses. We provide squares, rectangles, structural and ornamentals.

  • Drawn Tubing
  • Extruded Tubing
  • Extruded Rectangle, Round, or Square Tube
  • With or Without Seam
  • Custom Aluminum Shapes and Sizes Available

Getec Industrial offers turnkey drawn porthole aluminum tubing and drawn seamless aluminum tubing for customers who require tighter dimensional tolerances. These tubes are generally available for production orders.

In addition to standard profiles, we also produce custom shapes specifically designed by our customers for their own products. Enclosures, heat sinks, telescoping tubes, trim molding, lighting fixtures and odd shaped hollows and solids are examples of custom profiles we manufacture.

We produce profiles ranging in size from mini all the way to large circle size. To find your circle size, determine the diameter of the smallest circle that will entirely enclose the cross-section of your part. This will be the profile’s circle size. Please contact us for assistance with determining your circle size.

Our profiles are available in many hard and soft alloys such as 1100, 2014, 2024, 2219, 3003, 4032, 5086, 6005, 6061, 6063, 6101, 6105, 6463, 7050, 7075 and 7178 in various tempers. Aluminum alloys are selected for their unique characteristics including strength, corrosive resistance, machining and versatility.

Getec maintains high quality control standards and methods of continuous improvement by adding machinery, leveraging new and existing technologies, and constantly refining our methods and procedures to provide our customers with superior products, exceptional service, and expert support.

Our press technology allows us to extrude tubing to the smallest specifications. How small can we go? Contact us and find out!

Aluminum Extrusion Overview

The aluminum extrusion process really begins with the design process, for it is the design of the product–based on its intended use–that determines many of the ultimate production parameters.

Questions regarding machinability, finishing, and environment of use will lead to the choice of alloy to be extruded. The function of the aluminum extrusion profiles will determine the design of its form and, hence, the design of the die that shapes it.

Once the design questions have been answered, the actual extrusion process begins with billet, the aluminum material from which profiles are extruded. The billet must be softened by heat prior to extrusion. The heated billet is placed into the extrusion press, a powerful hydraulic device wherein a ram pushes a dummy block that forces the softened metal through a precision opening, known as a die, to produce the desired shape.

That is a simplified description of the process known as direct extrusion, which is the most common method in use today. Indirect extrusion is a similar process, but with some important differences. In the direct extrusion process, the die is stationary and the ram forces the alloy through the opening in the die. In the indirect process, the die is contained within the hollow ram, which moves into the stationary billet from one end, forcing the metal to flow into the ram, acquiring the shape of the die as it does so.

The extrusion process has been likened to squeezing toothpaste out of a tube. When pressure is applied at the closed end, the paste is forced to flow through the open end, accepting the round shape of the opening as it emerges. If the opening is flattened, the paste will emerge as a flat ribbon. Complex shapes can be produced by complex openings. Bakers, for example, use a collection of shaped nozzles to decorate cakes with fancy bands of icing. They’re producing extruded shapes.

As a global aluminum extrusion heat sink company, Getec Industrials is dedicated to providing you with aluminum extrusion profiles using quality products and services for turnkey extruded aluminum services and manufacturing.

Advantages of Aluminum Extrusion

When a designer specifies aluminum extrusion fabrication, he gets two sets of advantages; first the extrusion process, and second those inherit in aluminum.

The extrusion fabrication process is usually the most economical way to make parts that have a constant cross section, because the designer can put the metal “where he wants it.” Often, extruding is the only method that can be used.

Machining many lengths of metal to particular cross section is almost always more costly than extruding a similar number of pieces. Machining costs are additive; each additional piece requires almost that same amount of time and labor. Scrap resulting from machining often weighs more than the finished work.

Fabricating shapes by welding is also costly. Each work piece must be welded and costs do not decrease much with volume. In some instances the cost of the necessary welding jigs is much higher than the cost of the extrusion die that would be necessary to produce the same shape.

The cost of roll forming dies is very high compared to extrusion dies. Additionally roll forming cannot be used where wall thickness must be varied. The thickness of the metal remains the same after bending.

Sand and permanent-mold casting results in parts that may need extensive finishing before use. Aluminum extruding produces a wrought structure with relatively close dimensional control. Casting mold costs rise far more rapidly than extrusion dies as part complexity increases.

Extrusion dies are comparatively inexpensive. Generally, a simple shape will cost only a few hundred dollars. Forming dies and casting models generally run to thousands of dollars.

More extruders stock many standard dies, which the customer can use without a die service charge. Extrusion dies can be finished with less lead time than forming dies and casting molds.

Aluminum extruders will also store and maintain the die without charge. Most aluminum extrusion dies can be installed in a press quickly, so set up charges are nominal. Extrusion die life is long.

While many metals can be extruded, aluminum is the best all around extrusion metal because of its unique combination properties.

High Strength-to-Weight Ratio

Because the extrusion process “puts the metal where it is needed,” the result is a very strong part with relatively low weight.

Lightweight

The weight of aluminum is approximately one-third that of copper or brass or steel.

Corrosion Resistant

Aluminum has exceptionally good corrosion-resistance properties. It is self-protected by its own thin, transparent oxide film. Aluminum’s natural protective properties and color can be enhanced by chemical or electrochemical means.

Machines at High Speed

Aluminum is normally machined at speeds of 600 to 700 surfaces per minute and can usually be machined on standard equipment. Special lubricants, cutters and tools have been developed for aluminum to permit machining at even higher speeds.

Easily Joined

Aluminum alloys can be joined by welding, brazing, soldering, adhesive bonding, mechanical fastening by stakin, as well as by the use of nuts, bolts, rivets, etc.

Formed easily

Extruded shapes can be formed or bent using conventional equipment. Minimum radii and other specific points depend on a number of considerations: alloy, wall thickness, temper and shape.

High Electrical Conductivity

On a weight-to-weight basis, aluminum carries twice the current of copper. On a size-to-size basis, aluminum carries two-thirds the current of copper at considerably lower cost.

Excellent Thermal Properties

Aluminum is both a good heat conductor and a good heat reflector. Its ability to conduct heat is almost equal to that of the best conductors: silver, copper, and gold. Because of its ability to conduct heat, aluminum is used in heat transfer applications. And, because aluminum is also highly light reflective, it is used as a heat shield.
