Under one roof ...
... large crankshafts from ALFING

ALFING has deliberately chosen to carry out all steps of the crankshaft manufacturing process "under one roof".
The quality of a crankshaft depends to a large extent on the quality of the crankshaft forging. Over the decades we have developed our own forging competence, becoming a worldwide technological benchmark for crankshaft forging. After all the quality of our products is – and will always remain – what characterizes ALFING. And our customers know this.

Procedure for producing crankshaft forgings:

• 3D model of the crankshaft; development, simulation
• Manufacture of the dies and tooling
• Forging
  • Die forging
  • HfH forging (throw-by-throw forging)
  • TR forging (with Tadeusz Rut tools)
• Heat treatment

For these forging processes ALFING uses up-to-date forging equipment:

• Counterblow hammers
• Forging presses
• Pre-forging presses
• Heat treatment furnaces
• Quenching in oil, water or air
• Sandblasting
• Ultrasonic testing
  
• Crack detection
• Laboratories for testing the mechanical properties
