The main task of the Ventilation System is to introduce fresh air and expel stale air. In this system, metal stamping parts play the roles of "air guide", "connector" and "driver".

The automotive industry is the most mature, largest, and technologically advanced field for the application of metal stamping parts. It can be said that without stamping technology, there would be no large-scale assembly line production in the modern automotive industry.

The Cable & Wire Industry mainly involves metal drawing (for manufacturing wires) and extrusion (for creating insulation layers). However, in the stages of cable assembly, connection technology, and cable laying, metal stamping parts play a decisive role.

Numerical control equipment is the "mother machine" of modern industry. Although the core components of numerical control equipment (such as the bed, column, and spindle) are usually made of cast iron or mineral castings to ensure shock absorption and rigidity, metal stamping parts (and sheet metal processing parts) occupy the largest volume and have the widest visible area in numerical control equipment.
