a. Single-step mold In the one stroke of the press, only one mold of the stamping process is completed.
b. Composite mold There is only one station, and in the one stroke of the press, two or more stamping processes are simultaneously completed at the same station.
c. Progressive die (also called continuous die) There are two or more stations in the feeding direction of the blank. Two or two passes are successively performed at different stations in one stroke of the press. The mold of the above stamping process.
d. The transfer mode combines the characteristics of the single-process die and the progressive die, and utilizes the robot transfer system to realize the rapid in-mold transfer of the product, which can greatly improve the production efficiency of the product, reduce the production cost of the product, and save the material cost, and The quality is stable and reliable.
