Hjernø is highly specialized in producing technically demanding injection moulding tools. We have some of Denmark's best production equipment in a strong organization that ensures super high quality at very reasonable prices.

We specialize in finding innovative tooldesign solutions for tools even for very complicated parts, where we also use great precision in our super-modern production facility with tolerances down to 2-3 microns

Hjernø Værktøjsfabrik is one of Northern Europe's largest and oldest tool manufacturers. We were established in 1946, employ around 50 staff and produce an average of one new injection-moulding tool every day.



It is in the preliminary design phase that we create the basis for the perfect tool to mould the perfect part, and therefore we have a large tooldesign department with some of the best tooldesigners.

At the same time we like to be with you all the way in the project from part tooldesign to guaranteeing the finished production in the moulding department..


We have all the latest equipment and technology to manufacture tool parts within narrow tolerances.

We work in optimized processes that enable us both to be able to sell tools at highly favourable prices and to still be able to make money for future investments in new technology.




Our control department and control functions are the key to precise parts and parts, and in addition to our department with both tactile and optical certified measurement equipment, we carry out a thorough check of all functions and tool parts that are manufactured.

We can then measure and deliver a measurement report on the complete mould samples.
