In our lives, the use of molds has become very frequent. So, among so many molds, what are the ones we widely use? The molds we know include: progressive dies, high-speed progressive dies, ultra precision progressive dies, motor progressive dies, motor dies, high-speed stamping dies, continuous dies, fixed rotor dies, contact dies, etc.
So the so-called progressive die, also known as (connecting die): a punching die that completes two or more stamping processes on different parts of the mold in one stroke of the press. Composed of multiple workstations, each workstation completes different processing in sequence, completing a series of different stamping processes in one stroke of the punch press. After completing one trip, the punch press feeder moves the data forward according to a fixed step distance, so that multiple processes can be completed on one mold, generally including punching, dropping, bending, trimming, stretching, etc.

The motor iron core mold is a tool used in punching, forming stamping, forging, cold heading, kneading, powder metallurgy parts pressing, pressure casting, as well as forming or injection molding of engineering plastics, rubber, ceramics and other products, to make the blank into a specific shape and scale of the workpiece under external force.
