Forging is a metalworking process where compressive forces are applied to shape metal, typically using a hammer or press. It improves mechanical properties by aligning the grain structure.
🔹 Purpose:
- To produce strong, durable parts
- Used in high-stress applications (e.g., automotive, aerospace, tools)
🔹 Types of Forging:
- Open-Die Forging
- Workpiece is compressed between flat dies
- Suitable for large or simple shapes
- Closed-Die Forging (Impression Die)
- Metal is compressed in a die cavity
- High precision and complex shapes
- Cold Forging
- Performed at room temperature
- Better surface finish, high dimensional accuracy
- Hot Forging
- Done above recrystallization temperature
- Easier to shape, less stress on equipment
🔹 Materials Used:
- Steel (carbon, alloy, stainless)
- Aluminum
- Titanium
- Brass and copper
