Study Notes
Forging Types
- Annealing is the most common type of forging, used to reduce strength and increase ductility of work metal.
Open-Die Forging
- Allows metal to flow laterally without constraint.
Closed-Die Forging
- Creates flash in the gap between die plates.
Extrusion
- Involves forcing work metal to flow through a die opening to produce a desired cross-sectional shape.
Drawing
- Involves reducing the cross-section of a bar, rod, or wire by pulling it through a die opening.
