1、 Different properties
1. Composite mold: A mold structure in which a punching machine completes multiple processes such as material cutting and punching in one stroke.
2. Progressive die: composed of multiple workstations, each of which is sequentially associated to complete different processing tasks. A series of different stamping processes are completed in one stroke of the punching machine.
2、 Different characteristics
1. Composite mold:
(1) The workpiece has good coaxiality, a flat surface, and high dimensional accuracy.
(2) High production efficiency, not limited by the accuracy of plate shape and size. Sometimes waste corners can also be used for replication.
(3) The processing and manufacturing of mold parts is difficult and costly. Stamping and concave molds are easily limited by the minimum wall thickness and are not suitable for certain lower parts with small inner hole spacing and inner hole and edge spacing.
2. Progressive mold:
(1) Progressive die is a type of multi task continuous punching die. In a mold, it can include many processes such as cutting, bending, and drawing, with high productivity.
(2) Progressive mold operation safety.
(3) Easy to automate;
(4) High speed punching machines can be used for production.
(5) It can reduce the area of stamping machines and sites, as well as the transportation of semi-finished products and warehouse occupancy.
(6) Parts with high size requirements should not be produced using progressive molds.
