As a 3rd generation family run business, 
our FOUNDRY mainly produces OE-TURBO+EXHAUST-parts 
by use of semi-automatic shell & sand molding lines.


Metals:
- CAST IRONS: grey (= lamellar graphite cast iron) and ductile (= spheroidal /nodular graphite cast iron) irons
- DUCTILE CAST IRON SUPERALLOYS (ferrous alloys): D5S Ni-resist (austenitic high nickel-alloyed ductile = high-nickel heat and corrosion resistant = NiSiCr 35-5-2) and SiMo ( = Silicon-Molybdenum) irons 


In-house quality control equipment:
- Industrial X-ray detector
- Optical Emission Spectrometer (OES)
- Digital metallographic microscope
- High-frequency infrared carbon and sulphur analyzer
- Computer-controlled universal testing machine
- Other destructive and non-destructive testings
