Knierim Tooling is specialised in manufacturing high precision master plugs and heatable direct female tools for the production of rotor blades

Rotor blades are masterpieces of composite technology

Wind industry

Durable master plugs with high end precision are necessary to run a series production for efficient rotor blades with an optimal shape. In 2009 Knierim built the master plug for the largest rotor blade of the time with a length of more than 70 meters. It was built in 6 segments (tip, middle and root on each side) precise to the tenth of a millimeter.
