We offer manufacturing of components with both bimetallic solutions and other customized, unique surface treatment methods.

Metal build-up with the help of laser technology enables increased product performance and meets requirements for extreme surface and functional properties regarding wear, corrosion, and friction. 

With bimetal, we create solutions that change the view of what is possible. Our designers and technology solutions help you design and manufacture your own unique components. With our laser technology, we can combine different materials and thus tailor the properties of various components.

We can specially adapt entire surface layers or parts of components with regard to, for example, friction, wear, and corrosion properties. Some product examples that we manufacture are plain bearings, valves, tools, wear lining, piston rods, rollers, knife steel, bushings, axles, cogs, casings, and drive wheels.

Feed roller segment - Nordic Quick Systems

Duroc Laser Coating has helped Nordic Quick Systems with laser cladding of their unique feed roller solution for sawmills.

The replaceable segments, which in themselves mean a significant reduction in work in the event of maintenance stoppages, become even better when its surfaces are reinforced with DUROC TiC42 as the service life increases markedly. Fantastic news for all the world’s sawmills!

DUROC TiC42 is an additive material that contains titanium carbides, which create extreme abrasion resistance. DUROC TiC42 can be used for both cladding and impregnation depending on which surface properties are sought in addition to the extreme abrasion resistance.

Mold steels - Olofsfors

Significant service life increases with laser impregnation on mold steels

Olofsfors, which manufactures tracks for forest machines, previously had problems with the service life of the mold steel in their most demanding tools.

“The great stresses to which our mold steel is subjected to during the pressing of details previously meant that the steel had to be replaced at frequent intervals. Still, we could not be completely sure that the right tolerances were maintained between the exchanges,” says Caisa Johansson, production technician at Olofsfors AB. “To achieve the desired service life and reduced spare part costs, we turned to Duroc Laser Coating to test laser impregnation on our molded parts.” 

“In collaboration with Duroc Laser Coating and a molded parts manufacturer, a concept was developed by which the molded parts are hardened during manufacture and then surface-reinforced with laser impregnation.”

“The result was that we could use our molded parts twice as long without replacing them with new steels, which of course saves both time and money. This means that we avoid costly replacements of molded parts unnecessarily and that we can plan replacements in a much safer way when it suits our production. We have been given the opportunity to work proactively instead of reactively, which is very beneficial for us,” Johansson concludes.

Valve discs - Parker Hannifin

Lead-free valve discs with laser clading

Parker Hannifin has used bronze in a valve disc for several years in the manufacture of hydraulic machines, such as pumps and motors. With changed requirements regarding increased performance and elimination of lead in the bronze metal, Parker began to look around for new solutions.

Alternatives in the form of rolling, thermal spraying, thin film coating and laser surface treatment were evaluated through studies of the machine parts’ function and performance as well as the efficiency of the process.

Duroc Laser Coating’s laser cladding proved to be able to offer a completely lead-free laser bronze with superior performance compared to other methods. It is also a flexible solution that enables production adapted to demand and shortened lead times.

“Duroc Laser Coating’s solution has rationalized our manufacturing process and gives us an improved overall economy,” explains Mats Karlsson, purchasing manager at Parker Hannifin in Trollhättan.
