Quality Control

Viking’s Quality Management System is in compliance with American National Standard ANSI/ASQC Q9002–1994, which corresponds to the International Standard ISO 9002–1994. Viking has been registered since January 1994.

The scope of registration covers the manufacture of ferrous castings weighing from ounces to five thousand pounds.  Alloys include: Gray Iron, Ductile Iron, Ni Resist, Ni Hard, Carbon Steel, Low Alloy Steel, Heat and Corrosion Resistant Stainless Steels, Nickel and Cobalt Alloys.  Also, the manufacture of propriety wear resistant parts.

Viking maintains both spectrographic and sand testing labs in each foundry.  Tensile testing is performed on-site.  Nodularity checks are performed on each ladle of ductile iron.

In conjunction with the ISO registrations and quality labs, Viking uses Six Sigma methodologies and lean manufacturing concepts to continually improve both our products and processes.
