Creating a 180-degree bend in sheet metal is a crucial process in various industries, including HVAC, automotive, and metal fabrication. Achieving this bend requires specialized equipment, particularly a press brake with the right tooling. In this article, we will explore the available machines that can perform this operation within a 3x6 working area, focusing on their specifications and key considerations when selecting the best equipment for your needs.

Understanding the 180-Degree Bend Process

A 180-degree bend, also known as a full hem or a fold, involves bending the sheet metal back onto itself. This type of bend is often used for reinforcement, safety edges, or aesthetic purposes. The process requires precision and the right tooling to ensure a clean, accurate bend without compromising the integrity of the material.

The primary technique used to achieve this bend is air bending, where the sheet metal makes minimal contact with the die, allowing for greater flexibility in reaching large bend angles. This method minimizes tool wear and reduces the force required compared to bottom bending or coining.
