Tool quality is also a decisive factor in product quality. By maintaining our own design departments, we ensure that our know-how is also transferred to our own toolmaking departments. It goes without saying that the tools required, from creating a 3-D model and generating the CNC machining programmes, are available and communicate with the respective processing machines at our central toolmaking department in Grolsheim (HAY-TEC Werkzeugbau) as well as our toolmaking department in Tianjin.
