The process is highly suitable for creating complex shapes and works well for high-volume production, making it greatly favored by industries that require high degrees of precision and scalability. This minimizes manual operations on panel bending, thus eliminating human error and inconsistencies in the same product for different pieces.
Definition of a Panel Bender
The panel bender was invented as a more advanced automated metal-bending machine. Panel benders incorporate precision engineering, robotics, and software control to bend and shape metal sheets into a wide range of complex forms with exquisite accuracy and efficiency. Some might say that a panel bender can do everything an operator can do manually, but better and faster. A typical press brake is usually operated manually with a minimum of automated sheet handling. At the same time, on a panel bender, these systems are integrated along with programmable tooling for enhanced ease of manufacture.
The panel benders of today offer several excellent features: they can process materials of various thicknesses, generally ranging from 0.5 mm to 3 mm, depending on the machine model. With bending speeds of approximately 0.3 seconds per bend, this significantly reduces production cycle times.
