When ENGEL first unveiled a tie-bar-less injection moulding machine at the K trade fair in Düsseldorf in 1989, the reaction was mixed: technical fascination on one hand, open scepticism on the other. At that time, few would have predicted that this “revolutionary” design would evolve into one of the most successful technologies in injection moulding machinery. Today, 35 years later, ENGEL looks back on more than 85,000 tie-bar-less machines delivered worldwide – and continues to drive this innovation forward with a consistent focus on customer needs. At this year’s K 2025, ENGEL is presenting a world première: a new electric tie-bar-less injection moulding machine.
