Forging 101: Basic Of Cold Extrusion Forging

The cold extrusion forging process is pretty simple if you have been forging for a while. In fact, if you have been hot or warm forging, you will find the process quite simple because you will be skipping some of the steps.

Cold extrusion forging is growing popular because of the range of products one can produce. You can read here for more info about the products that this manufacturing is producing using the cold forging process.

If you want to know more about the cold forging process, we have put together the steps that you need to cold forge. Here are the main steps:

Metal Preparation

The first step is selecting the metal that you want to cold forge, and this choice is determined by the properties of the item you want to forge. Make sure it is of the right size in terms of weight. Then lubricate it thoroughly. Lubrication prevents the metal from sticking onto the die after punching, and it also helps to cool the billet during the forging pressing process.

Put Billet In the Die

You don’t need to heat, and you will just put the workpiece in the die. The die should have been made purposely for the item that’s to be formed. So, you should have had its design and made it with the specifications provided by the customers. It is a separate process that may be handled by another party.


Once the billet is in place, now you can start with the forging of the material. The punching step includes the compression force is applied to the metal to deform it. The force is too high that the material will reach its plasticity state, and this is how it is deformed to take the shape of the die. That’s how you form the new product with cold extrusion forging.

Removing Forged Part

The next includes a number of activities. It includes the removal of the flash and the removal of the forged parts from the mold or the die. These two activities can cause accidents, and that’s why they should be taken with care. Note that the formed product is still very hot, and thus you cannot touch it with bare hands. Make sure that you are using special tools to avoid accidents injuries.


The last step is finishing by giving the forged products a finer shape. However, cold forging usually produces near-net shapes, and this makes finish work pretty easy. But make sure that you are using the right equipment for finishing.
