Cold Forging Process: Advantages You Must Know

Forging has the capacity to deal with different temperature conditions, as it needs no heat to complete the process. For instance it includes cold forging, hot forging, warm forging.  It offers reproducibility & interchangeability. Through cold forging you can achieve a number of advantages like minimal contamination issues, greater strength, superior surface finish, improved dimensional control, to increase directional qualities. 

 

It is an effective method and also proven economically efficient method to produce large quantities of metal parts at very low price. Cold forging is achieved via machines accompanied with hammers, or through press for pressing, shaping, plus rolling steel's. The biggest advantage of cold forging is its cost effectiveness over hot forging and happens at room temperature. Most interestingly, cold forging saves upto 70% production cost plus produce little scrap and waste. 

 

Here in this article, we are going to dig out all the details about cold forging along with the advantages in detail. 

 

Cold Forging 

 

Cold forging deforms the metal whereas it is below from its recrystallization point. Cold forging is usually preferred when the metal is already a very soft metal, like for example aluminum. This process is generally less expensive than that of hot forging and the ending product requires little, or no finishing work. Oftentimes, when aluminum is usually cold forged into a given shape, it is the heat that is treated to strengthen the piece. This is also called “tempering.”

 

Despite the word “cold,” cold forging actually happens at or near according to room temperature. And The most generic metals in cold forging that require for applications are usually carbon alloy steels or standard alloy steel. One of the most important types of cold forging regarding a process also called impression-die forging, where the metal is always placed into a quality die that is affixed to an anvil. The metal is when it is hit by a descending hammer meaning hammering it in descending order and pushed into the die. Depending on the product type, the hammer can actually be dropped on the surface of metal various times in a very rapid sequence.

 

The advantages of cold forging include:

 

Forging processes, be it cold or hot forging, are generally not considered to be an energy saving or eco-friendly part of the all manufacturing process, but luckily cold forging is certainly the most common eco-friendly process of its unique kind in operation today. For those companies that care too much about reducing the carbon footprint of their nasty products, the cold forging process would help to reduce waste and lessen energy uses as compared to forging substitutes or alternatives that uses the heat.

 

Other reasons or advantages that stress why the cold forming process is the best and authentic or preferred choice include the:

 

lHigh quality of the surfacing material

lConsistency to all & each part manufactured

lEfficient usage of material. 

lno heat is necessary

lOffer increased reproducibility & interchangeability

lsuperior surface finish

lminimal contamination issues

limproved dimensional control

lgreater strength

loffers high ductility 

lgreat design flexibility

lrefines structure of metal

lIt also offers broad size ranges

lDemand fewer secondary operations

 

In addition to the reasons that we listed above and due to the eco-friendly factors, cold forming is also considered one of the most cost-effective or cost-saving methods of forging in today’s market. For example, estimates show that this process may reduce your cost as much as 40 to 60%!

 

How Cost Efficiency in Cold Forging Happen

 

Cost optimization in the process of cold forging usually starts with the raw material. To obtain the most and most cost efficiency you should manage the manufacturing process with great know-how and involve all tools and techniques. For instance, large batches of the cold extruded elements are manufactured on very high speed mechanical presses, but at the same time complex parts plus small series instead of hydraulic presses.

 

Application Considerations of cold forging process

 

Factors you should consider when do cold forging are include:

 

Material volume

 

Careful control if it takes over the material volume then it prevents stress and damage, specifically in closed forging, because the excess now has nowhere to escape.

 

Bonderizing

 

This coating process always improves material flow while the process reduces force, stress, and friction and improves surface quality.

 

Annealing

 

Annealing as you know softens the metal, by improving the flow of the material. It could be applied when work hardening occurs as an intermediate process before  the completion of the forging process. 

 

Lubrication

 

Lubrication is very critical during the process of cold forging. High-viscosity oil always protects against the all  metal-on-metal friction along with applying thin oil to dissipate heat.
