Specialist for complex castings since 1949
Georg Funk Eisengießerei GmbH & Co. KG is a medium-sized family business founded in 1949, headquartered in Aalen (Baden-Württemberg) and specialised in complex, customer-specific iron castings. Production covers grey cast iron with lamellar graphite (EN-GJL 150–350, including special alloys) up to 7,000 kg piece weight as well as spheroidal graphite cast iron (EN-GJS 400 to 700) and solid-solution-strengthened ferritic cast iron (MKV) up to 3,000 kg; the homepage states up to 9 t in hand moulding. Production ranges from hand moulding in cold-resin-bonded sand to machine-based series production with a fully automatic moulding line (Heinrich Wagner Sinto, parts up to approx. 80 kg) and shakeout-squeeze moulding machines (up to 200 kg), through to an in-house core shop (hand and machine cores, Novanol process). Melting takes place in an oxygen-enriched cold-blast cupola furnace with a heated forehearth; monthly capacity is 800 tonnes. The scope of services includes design consulting with Magmasoft simulation, casting finishing, painting shop, heat treatment, ready-to-install machined parts with cooperation partners, in-house logistics, and comprehensive quality assurance with mechanical-technological and non-destructive testing methods. Customers come primarily from mechanical and plant engineering, including machine tool, special machinery, drive and gearbox engineering, the food and packaging industry, infrastructure, and musical instrument manufacturing.

History
- 1949
Founding of Eisengießerei Funk by Georg Funk in Aalen; initially producing simple series parts such as waffle irons and flat irons.
After the founder's death, his nephews Josef Funk and Dr. Paul Funk join the company; establishment as a specialist for demanding, complex castings with a customer base in German mechanical and plant engineering
