In the cold-forming process, metal is formed without the use of heat by plastically deforming materials, usually at room temperature. This process shapes metal into the desired shapes using dies and punches, improving the material’s strength and structural integrity. It is widely used to create high-precision parts, reducing waste and providing affordable solutions in a variety of sectors, such as electronics, automotive, and aerospace, where precise shapes and tight tolerances are essential for optimum performance.

A Few Benefits of Cold Forming

Reduced Wastage
Reduced Wastage

Waste material needs to be removed to get the intended outcome in other manufacturing processes, such as machining.

Rapid Production
Rapid Production

Cold forming is an expeditious process. It can create 100 items per minute for some producers. Even better, the speed is matched by consistently accurate and high-caliber outcomes.

Enhanced Power
Enhanced Power

The process of cold forming, sometimes referred to as “work hardening,” gives the part strength while preserving the material’s grain structure. 

Reduced Energy Consumption
Reduced Energy Consumption

Cold forming, as opposed to hot forging, does not require additional energy to heat the material prior to manufacturing.

Cold Forming Process

Shearing, drawing, bending, and squeezing are the four main categories of cold forming. There are several distinct methods for forming metal at almost room temperature that fall under each of these categories.

  • Squeezing includes heading, thread rolling, cold rolling, forging, extrusion, and more.
  • Bending includes bending rolls, bending angles, and more.
  • Shearing includes cutting, piercing, and blanking.
  • Drawing techniques include embossing, wire drawing, and tube drawing.

A Few Drawbacks with Cold Forming

A Few Drawbacks with Cold Forming

Dimensional Limitations – A wider fastener diameter necessitates more pressure to crush the material into the proper form. A machine big enough to handle any size fastener could be built. 

Limitations of Shape – For some specialty parts with odd shapes, material cutting is still required even with the advancements in cold-forming procedures. As such, they better fit the machining process.

Pertaining to Materials – Some materials work better for cold forming than others, as was already mentioned. A variety of metals can be used, but if you limit yourself to the most effective ones, the outcomes will be better.

Metals That Are Good for Cold Roll Forming
Metals That Are Good for Cold Roll Forming

Many metals can be used for cold forming. As an illustration:

  • Carbon steels
  • Aluminum
  • Stainless steel
  • Copper
  • Nickel Alloys
  • Brass
  • Lead
  • Aerospace Alloys
  • Alloy steels
  • Bronze
  • Precious metals

Some materials, like cast iron, are just too brittle to use in this way.

Techniques of Cold Forming
Techniques of Cold Forming

Premium components are produced by cold forming. They require little further surface procedures because of their excellent surface finish. A few recommendations for cold-forming techniques are included below.

  • Apply reasonable margins of error to every measurement.
  • Prevent undercuts, chamfers, and sharp corners.
  • If you can, specify the simplified geometry.
  • Call out practical concentricity, flatness, & parallelism.
  • Specify the necessary levels of functional surface polish.
  • Think of materials that have been designed for cold shaping.
  • Recognize what the design’s mechanical specifications are.
What are the differences between hot and cold forming?

Cold forming is done at room temperature or slightly warmer than hot forming, which works with metal at higher temperatures. 

Is it possible to create intricate shapes with cold forming?

Yes, highly precise production of complicated and intricate structures is possible through cold-forming methods like extrusion and precision machining.

Is cold forming limited in any way?

Many benefits come with cold forming, however, not all materials or geometries may be a good fit. Cold forming can provide difficulties for some metals, such as cast iron.

What cost savings can cold forming offer?

Because there is less material waste and less energy used than in hot forming, and in some situations, no secondary machining is required, cold forming frequently has cheaper production costs.

How eco-friendly is cold forming?

Due to its generally lower energy requirements and reduced greenhouse gas emissions, cold forming can be seen as a more environmentally friendly technique than hot forming.
