Aluminum Extrusion Bending Thought and Execution Process
For effective bending and execution, there must be a thought process. This will guide the execution and will lead to great work if everything is followed according to plan. Below are some of the considerations to make during these processes.
Sample a few designers and you’ll get different opinions about bending aluminum extrusion processes. None of them are wrong because they opinionate based on their industrial experience and needs. For instance, the bending requirements for the aerospace industry may not be same as that of the agricultural industry. For that reason, the designs must be done specific to needs of each industry.
When doing large scale projects, it’s important to focus on the alloy to be used, weight, and costs to be incurred. It is to be understood that different alloys will bring out different outcomes. That explains why you need to consult experts of the field you want to supply extruded aluminum with.
Other critical factors to consider include the applications of that curved aluminum you want made. That information helps to shape the details that will be considered when defining curved aluminum extrusion specifications.
Shape complexity is also important to consider. This determines whether the project will be successful or not. Besides, it has a significant impact on the production costs.
Finishing options must also be considered. One may wonder why this should be the case. Well, a superbly finished aluminum will look better and serve longer. That’s value addition and means more satisfied clients.
Another important design aspect is the aluminum’s bendability. It’s easier to bend more bendable aluminum extrusions than the highly resistant ones. This means the bender has to be stronger and more efficient when dealing with less bendable Aluminum extrusions.
Bending aluminum extrusion isn’t the easiest of tasks to do. Balancing sides is even hard. For instance, making a symmetrically perfect shape requires precision and giving attention to detail at the bending point.
The use of asymmetrical metal will surely bring problems during bending. The more asymmetrical side will have severe twists than the symmetrical one. This may bring about some imbalance you don’t want to deal with in the future.
Designing Hollow Sections
It’s two times harder folding hollow sections. The hollow area must be well taken care of to prevent the pressure from folding the aluminum into the space. That means there must be a balance between the external force bending the aluminum tube and that which the inside can handle.
Another common challenge arises in cases where the manufacturer has used square corners. If that’s the case, the pressure from the bender will force the metal to crack. This may mean repeating some extrusion processes to correct the problem. To avoid such, manufacturers ought to use circular corner interiors. That will save the aluminum tube from extreme pressure that may lead to breakages.
There are other alternatives to this. Increasing the metal’s wall thickness is one of them. By doing so, you reduce the tension and pressure reaching aluminum’s interior. There’s also a use of internal support. This helps manage the pressure tending towards the inside of the hollow shape.
Extruded aluminum is also used to make channels as well as other complex structures. Shaping these complex products is a process that requires expertise. A significant amount of force is applied to twist the aluminum into channels. The arm exerting the force tends to move in the direction of the central axis. That way, an almost circular shape is made. Sometimes cylindrical aluminum shapes are made out of this action.
If you’ve seen a conveyor belt work, you’ll start to appreciate this process. In most cases, the belt or similar movers are made in this design. This helps smoothen processes in the manufacturing industry and/or transport. It brings about top level efficiency.
When making such products, it’s important to consider the functionality. Once employed for service, a lot of pressure is involved. That means friction will be there and wearing & tearing made inevitable. Quality alloys must therefore be used to minimize the number of maintenance schedules to be done.
Besides, when the friction is too much, the systems are likely not going to last long. That means you’ll have to spend extra money unnecessary calling repair experts to control the damages. That’s why you must get quality aluminum extruded products made of quality to avoid such inconveniences.
