The company began as a small, production unit for cemented carbide tools in Sandviken, Sweden when Wilhelm Haglund was assigned the job as manager of the unit in 1942.

Since then other cemented carbides have been developed, such as titanium carbide, which is better suited for cutting steel, and tantalum carbide, which is tougher than tungsten carbide.

Cemented carbide was first used in stretching mold area and has gone through cast iron mold, alloy steel mold, diamond dies, cemented carbide dies, polycrystalline module die and other developmental stages.

In recent years, the Cobalt content adopted in cemented carbide drawing die area in China is the same as that in Sweden Sandvik which is the leader of cemented carbide industry in the world.

The traditional grade for cemented carbide drawing dies in China is almost YG8, rarely YG15 and YG6X . Later, in order to obtain better wearing resistance, the Cobalt content has to be decreased.

The company active since 2010 is employing solely proprietary technologies based on CDS to develop and produce abrasives, cemented carbide blanks, and a wide range of components produced with metallic alloys, semiconductors and composites.

The "'Palmqvist method "', or the "'Palmqvist toughness test "', ( after Sven Robert Palmqvist ) is a common method to determine the fracture toughness for cemented carbides.
30.
With the development of commercially available cemented carbide ( 1920s ) and ceramic inserts ( post-WWII ), this trend accelerated, because carbide and ceramic are even more expensive and even less suited to serving as a shank.
