Rotary draw bending is a metal forming process used to create curved shapes from tubes or pipes. In this technique, a straight tube is clamped and rotated around a fixed die, which shapes the material into the desired bend. The process is efficient and allows for precise control over the bend radius and angle. This method is commonly used in industries such as automotive and construction, where strong, lightweight components are needed. Rotary draw bending can accommodate various materials, including steel, aluminum, and stainless steel, making it versatile for different applications.
