April 20, 2012 FIN – Norwegian manufacturer Dokka Fasteners has acquired an Ipsen ATLAS quench furnace to be installed at Dokka’s new heat treatment plant in Michigan.
The furnace will be used to produce hot-formed steel fasteners for the wind turbine industry.
The fastener systems rely on the technology of high-tension bolt assemblies heat- treated to withstand not only considerable loads of normal turbine operation, but also remain unaffected by salt water, storms or frost during the expected 160,000 thousand hours of operation, over 20 years and 17 billion load cycles.
The ATLAS furnace technology focuses mainly on a customized heat treatment process to produce steel parts with the material characteristics required for this application.

Dokka’s heat treatment facility in the Auburn Hills suburb of Detroit, includes sealed quench furnaces for hardening of steel, required tempering furnaces, handling tools for component loads and cleaning systems. AutoMag 4.0 automation software of Ipsen is used for automatic operation of the furnaces.

Dokka Fasteners is part of the Würth Group.
The main Dokka plant, located at their headquarters in Norway, has manufactured specialized fastener systems for several decades and recently expanded to triple its capacity. ©2012/2015 Fastener Industry News.
