Automotive molds seem to refer only to
Display Micro Screws with automotive body panels. However, to avoid confusion with the broader definition of Display
Micro Screws, automotive body panels are not Display Micro Screws. Display Micro Screws come in various forms and can be classified according to their working nature, mold structure, and mold material.
1. Classification by Process Nature
① Blanking dies separate material along closed or open contour lines. Examples include blanking dies, punching dies, cutting dies, trimming dies, etc.
② Bending dies bend blanks or their material along a straight line (bending line) to obtain workpieces with a certain angle and shape.
③ Drawing dies are used to form open hollow parts from sheet metal blanks, or to further change the shape and size of the hollow parts.
④ Forming dies lift blanks or semi-finished workpieces according to drawings. The shape of the die is directly replicated, while the material itself only undergoes localized plastic deformation. Examples include bulging dies, necking dies, bulging dies, wave-forming dies, flanging dies, and shaping dies.
2. Classification based on the degree of process integration:
In one stroke of a press, a single-operation die completes only one stamping operation.
① A compound die has only one station, where two or more stamping operations are completed in the same station.
In the blank conveying direction, a progressive die (also called a continuous die) has two or more workstations. In one stroke of a printing press, two or more stamping operations are progressively completed in different workstations.
