Managing the production, quality and delivery of custom extrusions
Schupan's custom extrusions team will consult on design strategies by looking at your extrusion design. We'll evaluate the part and determine the best production strategy based on your supply chain objectives.
Because we have experience and relationships with all of the nation's top extrusion makers, Schupan's custom extrusions team can manage the project skillfully.
We have developed a broad portfolio of business in custom shapes and tubing, such as bars and hollows for machining valves, manifolds, medical equipment, pneumatics, automotive, outdoor furniture,
and marine applications.
Schupan can help with custom plastic extrusions too. Contact our experienced custom extrusions team at 1-800-531-3434 for more information about custom extrusions.

Meet Tony Schiller, Schupan's Custom Extrusions expert
With 20 years of experience in the industry, Tony has managed and delivered hundreds of projects over the years and shares a bit of his expertise in extruding metals.
"How does the extrusion process work?"
Tony: The extrusion process involves pushing a heated billet through a die with a tremendous amount of force and precision to produce a desired shape.
The aluminum billets are heated to 800-1000 degrees F. prior to being extruded or "pushed." Steel dies are machined to the desired profile and placed in the extrusion container. The dies are also heated because both the die and the aluminum must be of a comparable temperature to extrude. The heated billets are then pushed through the steel dies at a force which can exceed 6,000 tons. This tremendous force creates the desired shape.
The process is very similar to the manner in which toothpaste is forced out through an opening when you squeeze the tube! In addition, die inserts can be added to form a wide variety of voids, hollows, ribs, channels, grooves, and other oddly shaped openings. The result is a part that has all the characteristics of wrought metal in the desired shape.
Extrusions are classified according to their general cross-sectional configuration, such as rod, bar, solid shapes, hollow shapes, semi-hollow, hollow, structural and tube. In general, the more intricate the shape the slower the metal has to be pushed and the more time it takes to construct a die.
"What are some of the factors that make for a good extrusion design?"
Tony: Uniform wall thickness makes a profile easier to extrude. It's an advantage if the internal and external wall thicknesses are similar because it decreases die stress and improves extrudability.
If the part is to be anodized, you should avoid profiles with large variations in wall thickness because they'll cool unevenly. This gives a visible structural unevenness that may be apparent only after anodizing.
A second factor is in the design of the corners. Extrusions can't achieve razor sharp corners, so corners should be rounded. Sometimes a design may demand sharp internal angles to enclose shapes. This can be overcome by incorporating a small cutout in the shape. Things like sharp tips should be also avoided as the tip can become wavy and uneven.
"How do you deal with extrusion designs for very small or thin-walled parts?"
Tony: The unique characteristics of thin-walled or very small parts calls for the production of these pieces in a mill that can best handle these kinds of designs. We have extensive experience with the nation’s best producers of aluminum extrusions and know who makes which parts best.
On all custom extrusion work, our strategy is to look at the prototype or design and determine how we can deliver your part with the best quality at the best price.
