AEC provides best Metal Shearing & CNC Press Brake/Bending services. Our metal shearing services allow a maximum edge length of 1250 mm & Material thickness,
Up to 6 mm Mild steel.
Up to 4 mm Stainless steel.
Metal Bending Services India
Metal bending services help you to form sheet metal by the application of force. Metal bending is used to apply a preferred shape to the metal. We carry out bending of sheet metal parts using hydraulic press brakes.
Our CNC Press Brake/bending services allow a maximum bending edge length of 3200mm.
The machinery is highly accurate when it comes to positioning and repetition, and has a wide array of capabilities, including hemming and seaming.
The minimum bending radius depends on the plasticity and thickness of the material. Generally, we recommend the largest possible bending radius to avoid cracking on the outer surface. we offers a minimum bending radius as small as 1 mm.
Up to 8 mm Mild steel.
Up to 6 mm Stainless steel.
What is Metal Folding?
Sheet metal folding is a very common forming method used to give the desired shape to structural steel, stainless steel, aluminium, etc. parts. A press brake is used to give the final shape to a part. It is important to bear in mind that bending is done after the cutting process.
Metal bending is possible for sheets (up to 6 mm) as well as plates (anything above). The possibility of executing a job depends on the manufacturer’s capabilities – maximum bending edge length and pressing force. Thicker materials and longer bending lines need more force. Whereas 200-ton pressing force is enough for most jobs – it can, for example, bend a 2 m line with a 10 mm thickness.
Metal Folding Chart
The calculations for tonnage requirements are based on the bending force chart as under.
A variety of bending methods exist to do the job. Although most of them are suitable for the average job, each has some specific use-cases and needs different press brake tooling as under.
V Metal Bending
The most widely spread folding method where a punch presses the sheet metal onto a die. V-bending has 3 divisions – air bending, bottoming and coining. Air bending is the most common of them. There, the sheet is not pressed onto the die but rather some way towards it until the desired angle is achieved.
U Metal Bending
Quite similar in terms of using a punch and die. Instead of a V-shape, it uses a U-shape. Thus, it’s main use is to produce U-channels.
Step bending – Uses successive V-bending to achieve large-radius bends. Smaller steps assure better and smoother quality.
Roll bending – A bending method that uses rolls instead of punches and dies. Great for producing parts with large radii or conical sheet metal details.
Another bending technique to produce angular bends. The big advantage over other methods is the lack of bending marks (usually left by the V-shaped die) on the part.
