In the hardware production process, usually what we call the stamping automation production line is the progressive die stamping production line, which consists of an decoiler, a straightener, a feeder, a press machine, a mold, and an automatic blanking line. To realize the automatic process of uncoil the coile, leveling the material strip , oiling the strip, stamping into parts, and collecting end parts off the line.

During the whole production process, the mold is the most important part of the workpiece’s formation. A mold is a model, used to complete the processes of injection molding, blow molding, extrusion, die-casting, or forging, smelting, stamping, and stretching in industrial production. The common types of mold we use are: stamping molds, plastic molds, blow molds, and die-casting molds.

According to the different processing technology, We commonly use punching mold, bending mold, drawing mold, and forming mold.

Punching mold: The punching is completed by a punch and a die. The punch and the die form a set of blades, which press the material in the middle, and the punch gradually approaches the die to separate the materials.

Bending mold: Bending is the use of pressure to plastically deform the material, which is then bent into a shape with a certain curvature and a certain angle.

Drawing mold: Drawing is to change the flat wool into hollow parts, or to further change the shape and size of the hollow parts.

Drawing mold

Forming mold: Forming process refers to various processing methods that use various local deformation methods to change the shape of parts or blanks.

According to the different steps of processing, we will classify the mold into single process mold, compound mold, progressive mold (continuous mold)

Single process mode

Application: Small capacity, large products

Single process mode

Composite mold

Application: Small capacity, larger product, simple size, saving material

Composite mold

Progressive die (continuous die)

Application: Large production capacity, more complex products, smaller product sizes

Molds have played an irreplaceable role in our lives. Most of our daily necessities cannot be done without molds. For example, computers, telephones, fax machines, cups, etc., and the outer covers of cars and motorcycle engines are also made of molds. It takes even more than 20,000 molds for a single car. So the role of modern life molds is irreplaceable, as long as mass production is inseparable from molds, especially in stamping production lines.
