Wat is CNC-motor?

Die CNC-motoronderdele-industrie is die grondslag en 'n belangrike deel van die ontwikkeling van die motorbedryf. Die voertuig het ongeveer 30 000 onderdele. Dit kan volgens hul funksies verdeel word in onderdele vir motorstelsels, onderdele aan die onderstel, onderstelstelselonderdele, elektriese en elektroniese toerusting en algemene onderdele. Volgens die materiaalklassifikasie kan dit in metaal- en nie-metaalonderdele verdeel word. Onderdele is metaalonderdele vir ongeveer 60% -70%, en nie-metaalonderdele vir ongeveer 30% -40%.

CNC automotive molds refer to molds used in the automotive field. They are called "mothers of the automotive industry." More than 90% of parts in automobile production rely on mold forming.

Generally, a car requires more than 1,000 to 1,500 sets of stamping dies. It accounts for about 40% of the total car output value. There are about 800 sets of plastic molds, about 300 pairs of sheet metal molds and about 100 sets of die-casting molds. Automobile stamping dies are important technical equipment for automobile production. Their design and manufacturing time accounted for about two-thirds of the entire car development cycle. They became one of the main constraints. Automobile stamping dies have the characteristics of large size, complicated working surfaces, and high technical standards, and are technology-intensive products.
