Flanging is a manufacturing process used to create a flange—a rim or edge that protrudes from the surface of a material. Flanges are commonly found in various industries, including metalworking, automotive, aerospace, and plumbing.

Flanging is a manufacturing process used to create a flange—a rim or edge that protrudes from the surface of a material. Flanges are commonly found in various industries, including metalworking, automotive, aerospace, and plumbing.

The flanging process involves bending or forming the material to create the desired flange shape. It typically begins with a flat or pre-formed sheet or plate of metal. The sheet is then clamped between dies, which have the desired shape of the flange. Pressure is applied, and the material is deformed or bent to form the flange.

There are different types of flanging techniques used in manufacturing, including:

1. Edge Flanging: In this method, the edge of a sheet or plate is bent at a right angle to create a flange. Edge flanging is commonly used in applications such as ductwork, enclosures, and automotive components.

2. Necking-In: Necking-in is a process where the diameter of a cylindrical tube or pipe is reduced towards one end to create a flange. This technique is often used in pipe manufacturing and fittings.

3. Orbital Flanging: Orbital flanging involves rotating a flange-forming tool around the circumference of a circular sheet or tube to gradually form the flange. This technique is often used in the production of pressure vessels, tanks, and pipe ends.

Flanging serves various purposes in manufacturing. Flanges can provide structural integrity, facilitate joining or connecting components, improve sealing capabilities, and enhance the overall functionality of a product or system. They are commonly used in piping systems, machinery, automotive parts, and assemblies where secure connections, sealing, or attachment points are required.

It's worth noting that flanging can be performed using different manufacturing processes, including stamping, roll forming, press brake bending, and specialized flanging machines. The specific method used depends on the material, dimensions, and desired flange characteristics.
