Profile bending refers to the process of bending various types of profiles, typically made from materials like aluminum, steel, or titanium alloy, into specific complex shapes, including curves, arcs, and custom geometries. Profile bending is widely used in industries such as construction, furniture, LED lighting, automotive, aerospace, and manufacturing for creating components like structural and decorative products.

The lead screw that moves back and forth needs to be lubricated, and the rotating ones are not used.
Just use a mixture of gear oil and butter.

In the industry, several commonly used aluminum alloys are ideal for bending due to their properties:

• 6063: Known for its superb formability and corrosion resistance, making it ideal for architectural applications.
• 5052: Offers high strength and good formability, commonly used in marine and automotive industries.
• 6061: Versatile with strong mechanical properties, suitable for structural applications when bent with the right techniques.
• 3003: Good for general-purpose bending, with decent formability and corrosion resistance, though not as strong as other alloys.
• 5083: Exceptional strength makes it ideal for marine use, though it requires specialized equipment for bending.

Aluminum profiles come in various sizes and specifications, and their bending capability depends on several factors (bending method, equipment, and bending radius). For example, extrusions with wall thicknesses from 2 to 15 mm can be bent, with bending radii as small as 300 mm. These are all possible.

When handling larger profiles, using the right machinery is crucial. This machinery carefully applies controlled force during the bending process to maintain the profile’s structural integrity.
The most common aluminum extrusion bending processes are roll bending, stretch bending, and mandrel bending. The method you choose should depend on the type of profile you’ve designed, its application, and production quantity.

Yes, BIT customizes profile benidng machines to meet specific needs, such as unique roll diameters or shapes. We also offer specialized bending applications, including I-beam bending, “V” channel forming, and half-pipe rolling for industries like mining. Challenge us with your unique requirements!

Currently, our PBC series machines provide wireless remote control operation.

Yes, you can customize the language version you need.

The PBC Profile Bending Machine significantly reduces flat ends by generating high bending forces, and its asymmetrical bending process and strong roll power ensure superior results, minimizing the unbent area to just 1/6 to 1/10 of what common profile bending machines produce, virtually eliminating flat ends.

The PBA 500, PBA 500+, and PBA 600+ models are all driven by servo motors and do not require hydraulic oil.

PBC series, and PBA 600, PBA 1000, and PBA 1000+ models require 46# anti-wear hydraulic oil.

We will provide the specific oil amount in the installation instructions.

There are no special requirements for the installation foundation of the PBA series profile bending machine, and it can work on the flat cement floor of the aluminum bending workshop.
For the relatively heavy profile section bending machine PBC, there are two cases: the three models of PBC-120, 140, 200 have a low body height and can work on the flat cement floor of an ordinary workshop. For PBH-300, 360,450, 500, 550, 600, 700, we recommend using a pit foundation to install the machine. It is worth pointing out that nearly 50% of the factories do not use a pit foundation for the two models of PBH-300 and 360, which is also a feasible solution.

Choose Appropriate Process Parameters: The key to avoiding cracking lies in selecting suitable bending radii and angles. Generally, the bending radius should be at least twice the thickness of the flat bar to avoid excessive stress concentration. Additionally, the angle should gradually increase to prevent the flat bar from experiencing excessive tensile forces instantaneously, which could lead to cracking.

Control Temperature Properly: The temperature of the aluminum flat bars during the bending process also affects the likelihood of cracking. Proper temperature control can reduce material hardness and minimize the risk of cracking. Depending on the situation, preheating before bending or locally heating the bending area using heating equipment can help alleviate stress concentration and reduce the risk of cracking.

Use Suitable Tooling: Proper tooling can alleviate stress concentration on the aluminum flat bars and provide adequate support. Using cushioning materials such as rubber pads or U-shaped grooves can reduce stress concentration and lower the risk of cracking.

Pre-processing of Materials: Before processing, aluminum flat bars can undergo appropriate annealing treatment or T6 heat treatment to increase their hardness and strength. This can enhance the tensile strength of the flat bars and reduce the risk of cracking.

• Point 1: Hardness of the Aluminum Flat Bars: Aluminum flat bars with high hardness are prone to cracking. It is crucial to select aluminum flat bars with high cost-effectiveness, focusing on the aluminum alloy and its state. The hardness of alloys from series 6 and 7 is higher than that of series 1, 3, and 5. It’s preferable to anneal them to the O state before bending. Quality of the aluminum flat bars also matters.
• Point 2: Thickness of the Aluminum Flat Bars: Overly thick aluminum flat bars are not conducive to bending. Thinner aluminum flat bars are preferred whenever possible.
• Point 3: Spacing of the Bending Radius (R): A larger bending radius (R) increases the pass rate, so it’s advisable to adjust the bending radius to be larger whenever possible.
• Point 4: Alignment of the Aluminum Flat Bars’ Grain Direction: The bending direction should be perpendicular to the grain direction of the aluminum flat bars, not parallel. For aluminum flat bar components with metal drawing requirements, it is preferable to perform the drawing after bending, if feasible in the manufacturing process, to reduce the risk of cracking during bending.

Before inquiring about an aluminum bending machine, it’s essential to gather pertinent information to ensure we recommend an informed decision aligning with your specific bending requirements.
Aluminum Alloys: Note the specific aluminum alloys you’ll be bending (e.g., 6061-T6). The hardness state of aluminum is important.
