Aluminum can be extruded into various profiles, from straightforward to intricate, to meet your requirements. Even though skilled designers can pack many features into a single extruded profile, it is not possible or practical to do so all at once. Joining techniques come into play at this point. hjaluminumwindow.com centers are subjected to composition and mechanical performance testing at the Huajian Aluminum Testing Center. In addition, it performs performance testing on doors and windows as well as measurements of the cross-section of aluminum.
It may be more practical to design two or smaller extrusion profiles that you can later join together to reduce the costs of die and tooling, create modular designs, or accommodate particular applications. However, selecting the most cost-effective and effective method of joining can take time and effort.
The design of joined or interlocking aluminum extrusions is provided with various options in this article. It also demonstrates how to select a suitable joining method, allowing you to adapt your subsequent design better.
Designers have access to various joints that they can incorporate into their products due to the adaptability of extruded aluminum. There are numerous options available, whether you need a design that is either permanent, semi-permanent, or non-permanent.
Because they are “butted” against one another without any unique mating surfaces, these joints are distinct from the rest of the joints on this list. These joints need to be held together with something other than geometry, like welding or fasteners, whether you assemble them in a butt joint, lap joint, tee joint, or another arrangement.
These joints bridge the gap between flat joints and more intricate geometries thanks to specially designed mating surfaces. They can be easily aligned between parts because of their shape, but depending on the application, they might need more than just geometry to stay together, similar to how flat joints work. Two typical examples are tongue and groove joints and half-lap joints, which limit movement in some directions without locking the components together.
Nesting joints can create semi-permanent and permanent assemblies by either drilling holes and attaching them with fasteners like rivets or by bonding them with an adhesive, weld, or another method.
The interlocking joint is one of the simplest types of geometry-based joints that do not require bonding or fasteners to join. This joint can be sturdy and is quickly dismantled by counter-rotating components that are out of position. It is typically constructed by rotating two parts into place. Similar to key-locked joints, you can add additional features to secure these joints and prevent accidental disassembly.
Slip-fit joints assemble extrusions by sliding them together along their lengths. These joints are sometimes referred to as sleeve joints. Even though this geometry-focused joint has reliable strength, it can be hard to put together, especially in small or crowded spaces. Read more about aluminum profiles from the site.
The mating geometries of these joints, also known as snap-lock joints, are typically reserved for more long-term applications. Snap-fit joints slide into a locked position that is usually very difficult to take apart because they rely on aluminum’s relatively high ductility to bend without experiencing permanent deformation.
In contrast to interlocking, slip-fit, and snap-fit joints, Nut tracks rely on more than just geometry to adhere to one another. A channel designed to accommodate a hex-head nut or bolt is included in nut tracks for extrusions, allowing you to join extrusions and other parts as needed. This highly customizable and modular design makes it simple to attach other add-ons and quickly assemble custom frames.
Similar to nut tracks, T-slot and V-slot aluminum extrusions require specialized hardware following their respective building standards.
Screw ports may be helpful if you attach a perpendicular component or protective cover to the end of an extruded segment. An easy and sturdy way to make it easier to add features to the end of your extrusion is to attach a screw boss to a profile that has been extruded.
End joints are like joints that use screw ports because they have special channels that make it possible to make joints at the ends of extrusions. End joints enable seamless end-to-end connection of extrusions, in contrast to screw ports, which permit the attachment of additional components to the extrusion. End joints can either extend extrusions in the same direction or create sturdy corner joints using an insert like a coupling or cleat.
Most of the joints on this list, whether permanent or non-permanent, are intended for fixed applications. The only exception is hinge joints. They are designed to maintain the extrusions’ alignment while allowing for limited rotational movement.
Geometry-based extrusions, known as key-locked joints, create a stable joint by utilizing two or more primary extrusions in addition to a key. The addition of a key prevents the direct extrusions from coming apart, even though they will not lock together on their own. The key must be inserted laterally, like slip-fit joints, but it may only need to run part of the length of the extrusion, depending on the application.
While not necessarily a joint in and of itself, skilled extrusion designers can create combination joints by utilizing a variety of joint types. Depending on the intended use, combination joints can increase the product’s versatility and stability. Incorporating a hinge joint into an extrusion profile with a nut track, for instance, would permit rotation around the hinge axis while securing components to the nut track.
