GIENANTH Group stands in the forefront and offers broad fulfillment
From the very first technical idea to the finished and mountable assembly, the production of our highly individual products at GIENANTH in every step of the project is based on leading German engineering expertise, technological lead, outstanding manufacturing know-how and long-term experiences lasting for centuries.

GIENANTH's production stands out in two iron casting procedures: Hand-mold casting and Machine-mold casting in the materials lamellar graphite cast iron (GJL), compacted graphite cast iron (GJV), Spheroidal graphite cast iron (SG iron); the in-house combination of both procedures allows us to provide an incomparably broad product.

Production Lines
The Machine-mold casting product line features mostly automated casting components and assemblies for the automotive industry. In this product line, we offer mass production of construction parts in a weight-range from 0.5 kg to 20 kg. Examples for assemblies are balance shafts, break housings, brake plates, screw collars, oil pump casings, crankshaft bearing caps, disc flywheels, hubs and many more.

The Hand-mold casting product line features individual large cast parts for on-site engine building and mechanical engineering and mainly the casting of motor blocks and cylinder heads for the heavy duty engines segment, ranging from 0.5 to. to 12 to. per product.

GIENATH GROUP is leading the markets with cutting-edge technologies, production techniques and highest process competence in BLUE CASTING by offering strong and reliable solutions: sustainable, eco-friendly, competitive, safe.
