Hot Die Forging: Everything Forging Parts Buyers Needed To Know

Most of the tough metals, such as steel, are forged through the hot die forging process. This is where a metal workpiece is heated under very high temperatures before deformation from its original form. The hot die forging includes the use of dies, which gives the forged parts the shape and size. Here is everything you need to know about the hot die forging process:

What is Hot Die Forging?

A process in which a metal workpiece is heated to crystallization temperatures before being pressed into different forms. A workpiece is heated about 75% of its melting temperature. These high temperatures are required to create plasticity. Metals forged through this method are; copper, carbon steel, nickel alloys, and titanium.

These are metals with a very high formability ratio, and high temperatures prevent damage during the deformation process as well as make them pliable to make intricate shapes.

What is the Process of Hot Forging?

The hot fording method is the commonly used method in many manufacturing industries. Metals workpiece is placed inside a furnace with very high-temperature ranges. The workpiece is heated above its recrystallization point, after which it is smashed into a die.

The dies and tools used in forging are also preheated to limit a reduction in the temperature of the workpiece when they are in contact. The process of maintaining the workpiece temperatures throughout the process by heating the dies is called Isothermal Forging.

Isothermal forging takes place in a vacuumed area or in a glass coating to avoid temperature reduction due to conduction. This also limits oxidation because there is no interference of inert gas inside the vacuum.

What are the Advantages of Hot Forging?

Hot forging is mainly used in automotive machines industries because the metals must be touched for resistance to wear and tear. Below are some of the advantages why hot forging is preferred.

Toughness and strength metal

Parts forged through hot die forging are more strong and tough when they cool down. This gives them the durability and the wear resistance needed.

Complex designs

During this process, metals are very high heated, and the tools are also preheated. This makes it easier to mold shapes and very complex designs to the maximum.


Metals are molded easily into a new form without breaking, and this avoids wastage of materials hence, a reduction of cost.
