Forging is a manufacturing process that involves shaping metallic pieces through their plastic deformation, which can be divided into two categories: hot and cold forging, each with specific characteristics and applications.

In both cases, forging is a metallurgical forming process that enhances the mechanical properties of materials, such as strength, toughness, and durability. Forged pieces have been known since ancient times for their structural integrity and reliable performance in applications that require strength and stability.

Hot Forging:

Material Preparation:
The process begins with the preheating of the material, usually a metal piece in the form of an ingot or bar. Preheating makes the metal more malleable and facilitates plastic deformation.

The preheated metal is then placed in a mold or between two dies and subjected to high pressure using pneumatic hammers, hydraulic presses, or drop hammers. This pressure causes the metal to deform and take the desired shape.

Controlled Cooling:
After deformation, the forged piece is often subjected to a controlled cooling process that enhances its mechanical properties. This process can be carried out with variable-speed cooling in water or oil to achieve the desired hardness or strength.
Hot forging is commonly used to create large-sized or complex-shaped metallic pieces, such as crankshafts, gears, automotive components, agricultural parts, and components for the naval industry. This process imparts superior strength and integrity to forged pieces compared to other production methods.

Cold Forging:

Cold forging is similar to hot forging but is performed at room temperature or slightly higher. This process is used to produce pieces with more precise details but tends to be less cost-efficient than hot forging. It is often used to create precision components such as screws, bolts, rivets, and watch parts.

Machining and Finishing:

Pieces produced by hot or cold forging can be further machined using CNC processes and treated to enhance their mechanical and anti-corrosion properties.
