Hot Forging Vs. Cold Forging Tool Manufacturing Process

At JYF machinery, we pride ourselves as being one of the aftermarket machines wear parts manufacturers churning out high quality tools. We use the highest grade of raw material and quality production processes that we are using. Forging is one of the techniques that we are using for the construction of our machine parts. It is also one of the techniques that have been for decades for the construction of metal products. However, it has been improved the years, and today we have one of the effective metal forging technique to wear parts production. In addition, we are doing two forms of forging which the hot forging and cold forging.

But what the difference between the two types of metal forging? Well, that is what we are going to let you know. We are going to discuss each of the forging technique and why it would be best for the construction of your machine tools.

Hot Forging

Hot forging is one of the most common forging techniques in the industry. It has been around for decades and has been improving over the years to what we have today. It is a technique that uses high temperatures are used to heat a piece of metal or workpiece above the crystallization point. At this point, it is easy to deform the rudimentary workpiece to the desired shape.

But it is also essential to note that temperature is one of the key factors. That is because the technique can be used for a range of metal types with each having different temperature. However, with the automated hot-forging system, we can get the right temperatures for each metal. Here is a simple breakdown of how various metals get heated:

  • 360°C to 520°C for Al-Alloys
  • 700°C to 800°C for Cu-alloys
  • Up to 1150°C for steel and alloy steel

Hot forging technique provides some of the best ways to manufacture machine wear parts. Wear parts constructed from hot forging offers excellent hardness and performance. There are also several pros and cons that come with hot forging.

Pros of Hot Forging

  • Increased wear part ductility
  • More flexible
  • Excellent surface quality
  • Cheap production cost


  • Less precision tolerance
  • Varying grain structures

At JYF machinery, we are using the most at improved hot forging technique for the construction of our machine wear parts.

Cold Forging

Cold forging is the opposite of the hot forging. As the name suggests, the technique uses low temperature to construct wear parts. Unlike the hot forging, you don’t need to heat the workpiece, but the process is almost the same. With cold forging, you need to cool the workpiece to the crystallization point. To achieve that, you must put the workpiece between two dies and stuck multiple time until it assumes the desired shape.

Cold forging

However, it is important to note that cold forging does not work for all metals. The most popular metals that can be used with the process are steel and carbon. That is why we have it as one of the manufacturing processes since we use the same machines.

There are many benefits that come with cold forging manufacturing, and that is what we are tapping on to. But there are also some drawbacks although the goods out weights the cons by far. Here are some of the major pros and cons.

Pros of Cold Forging

  • Less energy consumption
  • Requires less or no finishing
  • Improved dimensional control
  • Easier to impart directional properties
  • Material saving
  • Excellent surface quality
  • Easy to work with
  • Cheap

Cons of Cold Forging

  • Forms simple shapes only
  • Less ductility in wear parts
  • Residual stress could occur
  • Cannot work with some metals
Hot forging

At JYF machinery, we have some of the best cold forging appliances to ensure quality processing. We ensure that the quality of cold forged tools is one of the best that you can find in the market. Therefore, if you need cold formed tools, place an order with us.

In our factory, we are producing both hot forged and cold forged machine wear parts. We are also giving our buyers a vast range of choices to select from. We have invested in the state of hot and cold forging equipment in our factory. In addition to producing, we also provide external processing services for hot forging and cold forging. Feel free to contact us at any time or visit our factory.
