The German Vaillant Group is a global market and technology leader in heating, ventilation and air-conditioning solutions. One of its subsidiaries, HKR GmbH & Co. KG, supplies the Group with high-quality components, particularly precision-machined brass parts. Since it started targeting third-party customers four years ago, the medium-sized company has developed very successfully – not least to a corporate culture which involves everyone from the shop floor to the management.
