We understand that you may have questions about sheet metal folding and its applications. Whether you’re new to press brakes or seeking specific information, we’re here to help.
For the larger picture, be sure to check out our Metal Manufacturing Processes Guide, which covers other fabrication techniques, such as, welding and metal cutting.
What Is a Press Brake?
A press brake is a machine that is used to bend sheet metal. It consists of a sturdy frame, complete with a hydraulic or mechanical ram and a die set.
The sheet metal is placed between the ram and the die, and when pressure is applied, the metal is bent or formed to the desired shape.
Metal Folding vs Metal Bending: What’s the Difference?
Due to its machine-controlled folding angle, metal folding provides high precision and accuracy. It generally performs better with thicker materials than bending. Compared to bending, metal folding produces high-quality products that are free of surface scratches.
What Materials Can Be Folded?
A wide range of materials are able to be folded (such as plastics, mesh, and wood), but here at Salamander, we specialise exclusively in folding metals. We do this by using a press brake machine, which exerts high tensile strengths and shear forces to bend sheet metal into the exact shape you require, as established by the project drawings at the initial 2D or 3D CAD design stage.
What Is the Difference between a Press Brake and Folding Machine?
The key difference between a folding machine and a press brake is how they handle a workpiece. On a press brake, the flange is gauged and the rest of the part is rotated up.
On a folding machine, it’s the opposite – the part is gauged and supported on the sheet support system and the flange is turned up. Typically, press brakes are able to work on thicker, heavier metal, whereas folding machines are more suited to more delicate work.
What Are the Different Folding Techniques Used in Sheet Metal Folding?
Metal folding techniques are varied, with the most common types being:
- Bottoming
- Air Bending
- Coining
- Wiping
- Folding
- Rolling
- Joggling
- Hydraulic CNC Press Brakes
