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.

Large and medium-sized automobile cover molds are an important part of body manufacturing technology and a key link in forming the independent development capability of automobiles. Automotive mold products include automobile cover molds, tire molds, plastic inner and outer molds, automotive lighting molds, automotive bumper molds and instrument panel molds.

Automotive Mold Market Development

With the increase in the development of new passenger vehicle models, the number of new models introduced has increased year by year. With the growth of the automotive market and the intensification of competition in the automotive market, the capacity of the automotive mold market will grow rapidly in the future. This is also the result of the rapid development of the automotive industry and the rapid development of new models.

Luo Baihui, secretary-general of the International Model Association, said that the market demand for automotive panel molds mainly depends on the number of new models to be launched each year, and the number of new models to be delivered mainly depends on the development of new models. Passenger cars (including cars with less than 9 seats, MPV, SUV, and minibus, etc.).

Car Cover Mold Level

According to the category of cover parts and the requirements of car manufacturers, car cover molds can be divided into three levels: low-end, mid-end and high-end. Among them, the supply of molds with low technical content is oversupply, and the profit margin of the market is narrow. The competition in the middle-end mold market is becoming increasingly fierce, and high-end molds with high technological content are far from meeting the market demand, and the development space is huge.

In the production of CNC automotive molds, Essai Mold has formed its own automotive mold system.

1. Automatic 3D design

From a design perspective, the manufacturing of high-end automotive stamping molds requires a parametric design of the molds. We need to combine software template technology to actively and effectively conduct secondary development to form a series of fixed, standardized design parameters, design templates, and achieve complete correlation and drive of parameters. By changing the parameters of the mold parts, quickly change the CAE results, mold process, and optimize the structure of the mold.

2. Simulating Stamping Process-Computer Aided Engineering (CAE)

The manufacture of automotive molds is inseparable from effective plate forming simulation software, and high-end automotive molds require full-process finite element simulation technology. An effective plate forming simulation software can improve the success rate of high-end automotive mold development and greatly shorten the manufacturing cycle of high-end automotive mold development. It can simulate and analyze the formability of automotive stamping parts, determine the difficulty of forming, and the key areas prone to stamping quality defects.

At the same time, with the rapid development of automotive networking technology and the continuous improvement of electrification and intelligence, automotive electronics molds have also ushered in a wider market space. China's automotive electronics mold companies are actively deploying automotive networking services and key components and high value-added products such as integrated circuits, forming a synergy with the automotive electronics industry. In the context of the rapid development of new energy vehicles and smart cars. They can use molds to make intelligent driving interactive car products. This will provide huge development space for high-end functional components!

Automatic 2 Since 2001, the global mold industry has been growing steadily, with an average growth rate of more than 5%. By 2012, the global mold industry market reached $ 94.5 billion. In the United States, Germany and Japan, and other developed countries. Their automotive-related mold demand accounts for more than 40% of the total mold demand. On this basis, the global automotive mold market has reached 37 billion U.S. dollars. According to the ratio of the output value of automotive stamping dies to 40% of the output value of automotive molds, the global automotive stamping mold market is approximately 15 billion U.S. dollars. At present, North America, Europe, and Japan, as the traditional automotive stamping die demand markets, still occupy an important position in global demand, and their market demand growth rates will remain relatively stable in the next few years.

Rapid Development of the Automotive Industry

The stable and rapid development of the automotive industry has created a good environment for the development of the automotive stamping mold industry. In the production process of automobiles, more than 90% of parts need to be formed by molds. Manufacturing a car requires more than 1,000 to 1,500 sets of stamping dies. The production of a country's cars to some extent reflects the overall condition of the country's auto molds. After the 2008 financial crisis, the auto output of traditional car producers. Such as the United States, Germany, and Japan showed a moderate recovery. However, demand in emerging markets such as China, India, and Brazil has grown rapidly. It is expected that from 2013 to 2020, the global light vehicle production growth rate will reach 3.6%. Among them, the growth rate of developing countries and automotive molds will reach 5.7%.
