Forged Crankshaft Advantages

Forged crankshafts, often referred to as forged cranks, provide strength and reliability that far surpass any cast or turned bar stock, making these crankshafts the standard for any use that demands strength, consistency or quality. Our custom forged crankshafts have advantages over rough turned bar stock:

• Continuous grain flow
• Improved microstructure
• Finer grain size
• Reduced chance of voids
• Greater strength
• Better fatigue resistance

Custom Forged Crankshafts for Engines 

As a custom forged crankshafts manufacturer, we use open die forging techniques that allow us to produce forgings up to 3,000 pounds and 100" long.

Custom forged crankshafts are commonly used as specialized parts in heavy industrial applications, like engines, where the crankshafts are subject to extreme forces or pressures. Forged crankshaft strength, longevity, and quality when used in internal combustion engine (ICE) applications is crucial - it's an indicator of the overall performance and life span of the engine. Manufacturers in a number of industries increasingly prefer forged crankshafts over cast crankshafts due to their numerous performance and strength advantages.
