n the world of industrial manufacturing, forging is considered one of the most important methods for shaping metals. This process, known in Persian as Ahangari, involves forming metals under pressure and temperature, and is generally divided into two main categories:
- Hot Forging
- Cold Forging
In this article, we focus on cold forging—a process widely used in modern industries, particularly for producing high-precision, durable, and high-quality components.
What Is Cold Forging?
Cold forging is one of the oldest yet most effective methods of metal forming. It is performed at room temperature, without heating the metal. In this method, metal billets or wire are deformed using high pressure applied by industrial presses or power hammers until the desired shape is achieved.
Cold forging processes can be categorized in two ways:
Based on Equipment:
- Forging Hammer
- Press Forging
Based on Die Type:
- Open Die Forging
- Closed Die Forging
Why Is Cold Forging Important?
Cold forging is increasingly adopted in various industries due to its many advantages:
- Enhanced Strength and Durability
Deforming metal at room temperature increases its density, thereby improving its mechanical strength. - High Dimensional Accuracy
Because there is no thermal expansion, parts forged cold have better dimensional precision compared to hot-formed components. - Reduced Waste and Material Savings
Compared to machining, cold forging significantly reduces material consumption. - Ideal for Mass Production of Small Precision Parts
Especially in industries like automotive, electronics, and custom fastener manufacturing, cold forging plays a vital role.
