From the perspective of hardware mold development and design process, common molds should have the following processes:

1. The blanking die follows a closed or open contour to separate the material from the die. Such as blanking die, die, die, die, die, die, etc. These all play the role of blanking, so they are called blanking dies.

2. The drawing die is a die used to pull the material into the hollow part of the opening or to further change the shape and size of the hollow part.

3. The forming mold is to directly copy the blank or semi-finished product according to the shape of the convex mold and the concave mold, and the material itself only produces a partial plastic deformation mold. Such as bulging die, necking die, flaring die, forming die, flanging die, forming die, etc.

4. The riveting die uses external force to connect or connect parts in a certain order and form to form a whole.

From the perspective of hardware stamping process, the development and design of hardware molds can be divided into the following categories:

1. Single mold, this is the simplest mold in the mold, one can be formed, and only the punching process is completed in one action of the punching machine.

2. The compound die has only one process and action. In one action of the punching machine, two or more metal stamping dies can be completed at the same time in the same process.

3. Continuous mold. Some main molds are also called progressive molds. This is the more difficult one in the mold. It uses automatic feeding and uses two or more processes. In the punch, the role of a press is Next, two or more stamping dies are completed in different processes.

4. The transfer method, combining the characteristics of single-process molds and continuous stamping molds, uses the robot transfer system to achieve rapid transfer in the mold, which can greatly improve the production efficiency of the product, reduce the production cost, and save the cost of materials. Product quality is stable and reliable, which is the characteristic of mold maintenance.
