Die Set

Die set is a guide that secures dies to the press and enables accurate vertical motions. For the improvement of the precision of products, it is required that the die set surely hold dies, concentricity and coaxiality (flatness and perpendicularity) of cope and drag be accurate, and the replacement of dies be easy.
