Hörnlein's customers expect perfect quality along with high-efficiency high-volume production. A "true zero-defects approach" is also mentioned. This is only possible through world-class quality management. Industry 4.0 is already a reality now at Hörnlein. Perfect processes and systematic procedures are decisive in this type of environment. That is why they play a greater role at Hörnlein than in other companies. We developed our own production system for this – a unique interface between user and machine.
