coilforming
Coilforming is a manufacturing process used to produce complex, three-dimensional shapes from sheet metal. The process involves the use of a mandrel, which is a form or mold that the metal is wrapped around. The metal is typically in the form of a coil, which is unrolled and wrapped around the mandrel. The metal is then formed into the desired shape by applying pressure and heat. The process can be used to produce a variety of shapes, including cylinders, cones, and spheres. Coilforming is often used in the automotive, aerospace, and appliance industries to produce parts such as exhaust systems, fuel tanks, and appliance casings. The process is known for its ability to produce parts with high strength and durability, as well as its ability to produce parts with complex shapes that would be difficult or impossible to produce using other manufacturing processes.
