Metal fabrication, Metal forging means forging metal by using forces of compression. Forging metal is an efficient, faster, and more durable way of making equipment. Cold forging deforms metal below its recrystallization point. Cold forging deforms a piece of raw metal into a mold where it is shaped under high pressure and force.

Cold forging uses an alternative method to shape the material into a shape that is desired or needed. Cold forging is done at room temperature, it includes drawing, spinning, and extruding.

The metal is squeezed between two dies until a desired shape is produced. Cold forging produced parts that are used in the automotive electrical industry. You can get further details regarding cold forging through https://www.cxinforging.com/automobile-new-energy-vehicles/.

Understanding Cold Forging

Cold forging doesn't use heat to shape the new energy vehicles, cold forging process offers better reproducibility and interchangeability. Cold forging provides a better surface finish and contamination problems are reduced.it offers dimensional control. It can transmit directional properties onto the metal.

Cold forging processing produces lightweight new energy vehicles part that is suitable for the long term. Mostly products that are produced through cold forging are screwed, bolts suspension, etc. Cold forging requires a high temperature to shape metal at room temperature because the metal that is inserted is cold and it can be shaped only when high pressure is exerted.

Cold Forging Positive Points

For Cold forging, softer metals are preferred like aluminum which is cheaper and needs little finishing. The cold forging process has unparalleled advantages in the cutting process. Some of the main advantages are

Production Efficiency Is Super High

The cold forging process is very close to the shape of the required parts. It means the material used in cold forging is utilized highly, and it reduces the amount of secondary processing.

Doesn't Require Heat

As the name shows cold forging so doesn't require heat for the shaping of elements and the process is done at room temperature which saves energy. As it doesn't require heat it saves natural resources and electricity also are a source of heat.

High Material Utilization

In cold forging, material is fully utilized as the metal is shaped into the required shape and it requires less finishing. And it does not produce waste so that is why all the material is utilized in it.

Have Good Dimensional Accuracy

Cold forging has a good consistency, as the work piece has high mechanical properties, good quality surface, and greater strength, is lightweight, last long, and has grain flow.

Cold Forging Negative Points

Cold forging has many disadvantages as its requirements are high:

Undesired Residual Stress

It produces undesired residual stress, metal with high carbon content cannot be processed easily and is difficult to process complex parts.

High Force

As cold forging uses softer metal so they are less ductile, this is why they need higher forces.

High-Quality Metal

Because high-quality force is needed so it demands heavier and high-quality metal. Molds that are used to shape metal require high-quality alloy, the blank needs to be accurately cut, diameter and length tolerance must be small, if it is larger it may damage the mold or the product can be cracked.

Directional properties

As cold forging is capable of Directional properties on metal, these properties can be harmful

Clean surface

The surface of the metal must be neat, clean, and scale-free.

Application of Cold Forging

Cold forging produced parts that are used in the automotive electrical industry

• Parts for seat
• Gears of different types
• Parts for starter motor
• Motorcycle part
• valves and switches
• Stems and shafts
• Agriculture machinery

Ending Remarks

Cold forging has close dimensions, and good surface finishing quality, and it uses low-cost materials like aluminum because they are softer and can be molded into the required shape, and to obtain the required strength without heat treatment. In cold forging bar stock is inserted into a die and then squeezed with a second closed die. In cold forging vertical presses are used instead of horizontal presses.
