Hot forging with Multi-Stage Presses

For our large-series production, we rely on a broad range of fully automated horizontal multi-stage presses that is unmatched worldwide.

Our forging facilities achieve a part yield of 10 800 parts per hour at a rate of 180 strokes per minute, and can produce precision components with an outer diameter and part height of up to 180 millimeters as well as a finished-part weight of around six kilograms.

Our products stand out due to their high levels of component precision and low machining allowances. And this is achieved without die draft angles and residual flash. Besides their precision, the forged parts are also characterized by optimum fiber flow, high part strength, a high degree of material utilization and low machining efforts.

What is hot forging?

What is hot forging?

Warmumformung

Modern cars should have spontaneous power, consume less fuel and provide a high mileage. This demands light and compact components with the highest levels of strength. Hot-forged parts fulfill these requirements.
Hot-forged parts are thus used extensively on those parts of a vehicle which are highly stressed and which place great demands on safety, reliability and service life
.


Hot forging at temperatures of between 1100 to 1250 °C enables highly sophisticated parts to be produced, which have a fiber flow that is adapted to the component geometry and which thus demonstrate good strength properties.
SEISSENSCHMIDT favors closed-die forging without flash as a hot-forging process. During such precision forging operations the tools create a completely closed hollow form. This means that the starting weight of the billets corresponds exactly to the weight of the finished forged parts.
