1. Hot working: Hot working is a metalworking process that involves shaping metal at high temperatures, typically above the recrystallization temperature of the metal. This process allows for easier deformation of the metal and can result in improved mechanical properties.
2. Cold working: Cold working is a metalworking process that involves shaping metal at room temperature or slightly above. This process is used to improve the strength and hardness of the metal, as well as to achieve tighter tolerances and better surface finish.
3. Extruding: Extruding is a metalworking process that involves forcing a metal billet or ingot through a die to create a specific shape or profile. This process is commonly used to produce long, continuous shapes such as rods, tubes, and profiles.
4. Casting: Casting is a metalworking process that involves pouring molten metal into a mold to create a specific shape. Once the metal has solidified, the mold is removed to reveal the finished part. Casting is a versatile process that can be used to produce complex shapes with high accuracy.
5. Forging: Forging is a metalworking process that involves shaping metal through the application of compressive forces. This process can be done using various methods, including hammering, pressing, or rolling. Forging is commonly used to produce parts with high strength and toughness.
6. Drawing: Drawing is a metalworking process that involves pulling a metal rod or wire through a die to reduce its diameter and increase its length. This process is commonly used to produce wires, tubes, and other long, thin metal products. Drawing can also be used to improve the surface finish and mechanical properties of the metal.

Hot Working Processes:
- Forging: Shaping metal by applying compressive force while heated to temperatures above its recrystallization temperature. - Rolling: Passing metal between two rotating rolls to reduce its thickness or shape its cross-section. - Extruding: Squeezing molten or heated metal through a die to create continuous shapes with specific profiles.
Cold Working Processes:
- Drawing: Pulling metal through a die to reduce its cross-sectional area and lengthen it without heating. - Rolling: Similar to hot rolling, but performed at room temperature to enhance the metal's strength and surface finish. - Stamping: Using a press to cut or shape metal sheets by applying force through a die.
Casting:
- Pouring molten metal into a mold and allowing it to solidify to create a desired shape.
Extruding:
- Forcing heated metal through a die to create continuous shapes with specific cross-sections.
Forging:
- Hammering, pressing, or rolling heated metal to shape it into desired forms by applying compressive force.
