Materials for Bending
Aluminum CNC Bending
Aluminum is a superior metal in terms of strength-to-weight ratio. It offers High Machinability, ductility, and thermal & electrical conductivity. Parts with aluminum also become highly resistant to corrosion.
Subtypes: 5052, 5083, 6061, 6082
Brass Bending Part
Golden shiny color, low friction, excellent Machinability, and high electrical & thermal conductivity. Brass can be easily machined and the best choice for low-friction applications.
Subtypes: C360, H59, H62
It offers good strength, hardness, and excellent corrosion resistance with superior heat and thermal conductivity. It also has a very appealing aesthetic.
Subtypes: 101, C110
Steel Sheet Metal Bending
High mechanical strength, toughness, resistance to wear and fatigue, and sturdiness. In addition to carbon, other alloying elements can be added depending on the needed mechanical and physical qualities.
Subtypes: 1018, SPCC
Stainless Steel Sheet
High mechanical strength, Thermal, Wear, and Corrosion resistance. Stainless steel is low-cost and can be machined easily. Parts made from Stainless steel are durable and do not lose that strength over time.
Subtypes: 301, 304, 316

What is Sheet Metal Bending?
Bending is the manufacturing process in which Sheet metal is transformed into desired shapes by applying pressure along an axis. The shape is created during the bending process through plastic deformation in the bending position.
The traditional bending machines struggle to obtain correct bending angles, and it may take a long time for them to turn at proper angles since they must undergo numerous Hits & Trial Steps. While CNC bending machines operate according to pre-programmed instructions and allow the setting of different bending angles following the desired bending positions, they are faster and more accurate.
CNC bending method produces exact dimensions according to the uploaded CAD file because this technique is more automated and accurate in bending sheet metal than traditional ones. The sheet is shaped using a hydraulic mechanism (Press brake) that the computer can fully control.
- Complex shapes are possible, including triangles with bent corners and all types of curves up to entire circles.
- Less production time
- A high degree of accuracy on bending angle
- Less production time
- High Working efficiency
- Design flexibility
- Less post-processing
- Reduced number of parts
Types of Bending
In air bending, the outside edges of a die & punch tip are used to create the bend on sheet metal. Because it requires significantly less tonnage to bend than other forms of bending, it is the most popular among manufacturers. Additionally, air bending offers more flexibility in shape and bending radius.
Rotating cylinders with a V-Opening are used in rotary bending. It is used when a bending angle larger than 900is required. For pre-painted or damaged surfaces, it works best. The roll bending process is used for sheets and bars. The primary purpose of this process is to induce a curve shape bar into the straight plate.
Coning produces consistent bending over sheet metal workpiece like coins that are uniform in shape. It is a straightforward process in which sheet metal is stamped between the punch and die. With Coining, a small tolerance & a high degree of reproducibility can achieve. Additionally, the interior radius can be decreased to any desired level.
Folding, wiping, Joggling, and Elastomer are the other types of bending used in manufacturing.
CNC Bending is used in various industries to make several pieces of equipment and parts. Some of them include;
- Automotive components
- Pipes and tubes
- The exterior of aircraft and other parts
- Hardware components

What is the Bending Tolerance that Prolean Offers?
Our fully computer-controlled Bending machines can maintain a tolerance of ± 0.25 mm in length and ±1 degree in bending angle.
What is the minimum bend radius I should maintain in my design?
The sheet metal’s thickness affects the minimum bending radius. A straightforward rule in manufacturing states that “the bending radius cannot be less than the thickness of the sheet metal.” So, for instance, the bending radius should be at least 1mm if your sheet is 1mm thick.
