Closed-die forgings

Gesenkgeschmiedete Teile

We produce drop forgings with 200 years of experience – from forged blanks to ready-to-install components. Our dimensional spectrum ranges from 5 kg to 3.5 tons, from a few centimetres to 4 meters in length.

Our products are used in large engines, railroad technology & mining, the oil & gas sector, the food industry and high-quality special applications. We are among the market leaders in many areas and stand for the highest quality.

We forge on forging hammers with 160, 320, 400 and 630 kNm and on presses with 31.5 and 45 MN. We attach great importance to high value creation, flexibly from a single source. Our hammers and presses meet the highest accuracy requirements. Die production is carried out 100% in-house.

We also have a wide range of heat treatment options, mechanical processing options (turning, milling, drilling) and an in-house paint shop for ready-to-install components. We ensure quality control with a wide range of options and our own laboratory. Our own engineering team provides individual customer advice.
