What is CNC Automotive?

The CNC automotive parts industry is the foundation and an important part of the development of the auto industry. The vehicle has about 30,000 parts. They can be divided into automotive engine system parts, body system parts, chassis system parts, electrical and electronic equipment, and general parts according to their functions. According to the material classification, it can be divided into metal parts and non-metal parts. Among them, metal parts account for about 60% -70%, and non-metal parts account for about 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.
