Warmpresswerk Max B. Schachmann
Warmpresswerk Max B. Schachmann GmbH is a drop forge established in 1959 in Niederstadtfeld in the Vulkaneifel. The company manufactures individual forged parts by hot die forging on nine forging presses with component weights from 0.2 to 25 kg, diameters from 40 to 260 mm and heights up to 200 mm. In addition to steels such as quenched and tempered steels, case-hardening steels, tool steels and heat-resistant steels, special materials are forged, including titanium alloys, nickel-based wrought alloys, molybdenum alloys (TZM), tantalum and pure iron. An in-house toolmaking department manufactures forging dies on CNC lathes and 5-axis milling machines; in addition, the company offers heat treatment, surface treatment, sizing and final inspection. The products go, among others, to mechanical engineering, the automotive and commercial vehicle industries, the valve, medical, agricultural, pressure equipment and shipbuilding technology sectors as well as food production. Around 100 employees produce on a fully automated robotic system.

Additional services
Quality and Certification
Every forged part undergoes a visual inspection as well as a one-hundred-percent height check via a light barrier with counting device; depending on standard and customer requirements, magnetic particle testing, hardness and mix-up testing as well as measurement with micrometers and dial gauges follow. The counting device is checked annually as part of measuring equipment monitoring.
