11. What is the difference between forging and coining?
Forging vs. Coining: Key Differences
| Aspect | Forging | Coining |
|---|---|---|
| Definition | Shaping metal by applying compressive forces, usually at high temperatures, to form parts or tools. | A precise stamping process where metal blanks are compressed under high pressure to imprint detailed designs, typically at room temperature. |
| Purpose | To form rough or semi-finished shapes with improved strength and grain structure. | To produce finely detailed, flat or slightly raised images/designs on metal surfaces (e.g., coins, medals). |
| Process | Deforming metal using hammers, presses, or dies — often hot forging. | Compressing metal blanks between engraved dies under high pressure (cold working). |
| Material State | Often involves heating the metal to make it malleable (hot forging). | Usually done cold or at room temperature to retain metal detail and finish. |
| Typical Products | Automotive parts, tools, hardware, structural components. | Coins, medals, badges, precision parts with detailed surface designs. |
| Detail Level | Lower surface detail, focused on shape and strength. | High precision, intricate surface detail and relief. |
| Equipment Used | Forging presses, hammers, anvils. | Coining presses, hydraulic or mechanical presses with precision dies. |
Summary:
Forging is about shaping and strengthening metal parts, often at high heat, with less focus on surface detail.
Coining is a high-precision stamping process that imprints detailed designs onto metal blanks, mostly used for coins and medals.
