Building
an extrusion Structure can be a tough job if you are not accustomed to the
intricacies of the process. This article further helps you understand how to
make an efficient Aluminum T-slot extrusion structure.
Adding aluminum T-slot extrusion structure further
enables the quicker manufacturing and design of the structural frame. However,
with some design analyses and considerations, the structural integrity of these
assemblies can be drastically improved. This article further explains some of
the ways in which you can build rigid, trusty, and industrial-grade aluminum
T-slot extrusion structures.

Choose
the Correct Profile:
This is considered to be one of the most critical
points to remember while building such structures. These profiles vary in a lot
of ways. Based on the moment of inertia, the rigidity of these structures with
the same outer dimension (45mm x 45mm) can considerably vary. Some profiles can
give rise to a 40% stiffer beam as well. Not only that, but the cross-section
area is another important consideration while manufacturing these structures.
Given that the cross-section area has a direct
impact on the weight of the structure, it is very vital for the manufacturer.
Some of the best profiles of these Extrusion accessories are highly rigid
but lightweight. The ratio of the moment of inertia to the surface area is one
of the best indicators.
In order to successfully decide if a structure’s
profile meets the design parameters you have set in your mind, you can start by
approximating the applied load on the structure and each of the separate Extrusion machinery by Packagingnavi from the basic static calculation and free
body diagrams. Once that has been figured, there are some formulas you can use based
on the application, to bend stress and calculate the maximum deflection for
each of the critical extrusion. A comparison between the maximum bending stress
along with the yield strength of the material being used provides the order of
magnitude that the extrusion capacity needs to withstand the said load.
However, the order of magnitude should be used along with other precise values
and factors like the structure’s own weight and shear stress.

Make
the Right Decision while Selecting the Extrusion Joint Configuration:
Once you have carefully selected the apt profile,
you are only halfway at coming up with effective structures. The assembly joint
configuration is the second most vital consideration as it can significantly
affect the structural rigidity and integrity of the design. Nevertheless, one
thing you should avoid in the design of these structures is letting the
assembly joint solely rely on the friction to support the weight. It can be
significantly improved by placing one extrusion accessory on top of
the other. This way, the assembly plate holds all of the pieces together but
withstands only a minimal amount of force. However, you cannot always avoid relying on
friction when it comes to the assembly joint. In such situations, the designers
need to calculate how much friction can get generated from one fastener, and
multiply that with the number of screws that are present.
With these points, you can ensure to design and
manufacture efficient yet effective aluminum T-slot extrusion structure.
