Pendant le cintrage, une pièce est placée dans la première fente de positionnement et une partie devant être cintrée est située entre le bloc de moule supérieur de cintrage (6) et le bloc de moule inférieur de cintrage (9). Une fois que le moule supérieur (2) et le moule inférieur (1) sont fermés, le cintrage de la pièce peut être rapidement réalisé, de sorte qu'un mandrin de traitement long de 150 mm n'a pas besoin d'être réservé au niveau des deux extrémités de la pièce et le taux d'utilisation d'un matériau est considérablement amélioré. Le temps takt est de 200 PCS/H et le goulet d'étranglement du temps takt de 80 PCS/H en production continue est surmonté. Un processus de cintrage est omis ; une cintreuse, un ensemble de moules de cintrage et un opérateur deviennent superflus ; et les coûts de production sont réduits.
