Cost Effective Finishing of Powder Forged Connecting Rods with the Fracture-Splitting-Method 910157

The powder forging process closes the gap between conventional powder metallurgy and die forgings. Adequate shape of the preform and strict respect of its given volume avoids forging burrs and delivers closer tolerances.
Powder Forging achieves higher density and therefore remarkably improved mechanical properties as compared to the conventional PM process.
An example of application for a component with high dynamic stresses is the connecting rod. High precision and low weight tolerances already lead to less machining operations on sinterforged connecting rods than on classical forged or cast components. Using the patented KREBSÖGE fracture splitting procedure, subsequent costly machining operations become obsolete. This leads to remarkably lower investments for new machining lines and to cost savings for production.
