What are the ways to cold form tubing?

There are several ways to cold form tubing, depending on the desired shape, size, and material of the tubing. Here are some common methods of cold forming tubing:

  1. Bending: The tubing is bent to a desired angle and shape using a bending machine or tools such as mandrels, wipers, and pressure dies. This method is commonly used to produce bent tubing for structures, frames, and piping systems.
  2. Swaging: The tubing is reduced in diameter by using a swaging machine or tool to compress the material and form it into the desired shape. This method is commonly used to produce tapered or conical shapes for applications such as connecting two different sized tubes or creating a funnel shape.
  3. Flaring: The tubing is expanded at one end to create a flared shape using a flaring tool or machine. This method is commonly used to connect tubing to fittings or other components.
  4. Beading: The tubing is compressed and shaped using a beading machine or tool to create a bead or bulge in the material. This method is commonly used to reinforce tubing ends or create a connection point for other components.
  5. Cold rolling: The tubing is passed through a set of rollers at room temperature to reduce the wall thickness and change the shape of the tube. This method is commonly used to produce tubing with precise dimensions and a smooth surface finish.

Overall, cold forming tubing is a versatile process that can be used to produce a wide range of shapes and sizes for various industrial applications.
