The Karhula foundry is one of the largest manufacturers of stainless castings for pumps, mixers, and agitators in the world. It supplies demanding steel and special cast iron castings primarily to the company’s own factories, and to external special customers. We can draw on more than 50 years of experience in the manufacture of duplex steel grades, and we also have a license to cast the fully austenitic Avesta 654SMO steel.
The casting patterns are manufactured using a high-speed, five-axis machining center. Of the total annual production of some 50,000 castings, almost 90 per cent are made of stainless duplex or superduplex steel grades. The net weights of our castings range from 0.5 kg to 8,000 kg. Molds at the Karhula foundry are made by using a method based on a no-bake sand or the Replicast CS Ceramic Shell molding method.
The Karhula foundry applies safety, quality and environmental systems approved by Det Norske Veritas.
