AVK
Supplied specialised castings to AVK for more than 20 years before AVK acquired the foundry in May 2025. The acquisition announcement identifies AVK as the foundry’s largest customer.
Frese Metal- og Stålstøberi in Slagelse supplies complex sand castings in nickel-aluminium bronze, bronze/gunmetal, stainless steel and duplex steel. Typical components include pump casings and impellers, valve bodies, propulsion parts, firefighting components and heat-exchanger parts for corrosive operating environments. The foundry offers joint development, casting simulation, patterns, sand-printed prototypes, machining and agreed testing. The foundry was acquired by AVK in May 2025, separately from the valve business sold to Vexve.
