With the trend towards lightweight vehicles, the use of automotive plastic components is increasing. Developed countries regard the amount of plastic used in automobiles as an important indicator to measure the level of automobile design and manufacturing. German automobile plastics account for 15% of the overall material. In recent years, my country's automobile industry has developed rapidly. At present, the annual output of automobiles exceeds 4 million. Referring to foreign trends, the annual use of modified plastics in the automobile industry will exceed 500,000 tons. With the rapid development of science and technology of the times, the continuous progress of new materials, and new processes, nowadays people put forward a series of higher requirements for the quality of automobiles, mainly in terms of comfort, safety, environmental protection, and aesthetics. In this context, the lightweight and low cost of automobiles have become the dominant of industrial design.
As one of the future development directions of the automotive industry, plastic parts are increasingly valued by the industry for their molding and processing technology. As the development direction of auto parts, the production of plastic parts should not only achieve energy saving, environmental protection, and functional diversification in production but also simplify the manufacturing process and process. Processing plastic parts into auto parts naturally reduces the use of metal. As the use of plastic parts continues to increase, the cost of using the car and the weight of the car body begin to decrease, and it can improve the energy saving of the car. row effect.
In the production process of automobiles, aluminum die casting for automobiles has gradually developed into plasticized parts, and the application of plastic parts has become more and more extensive, including automobile seats, ceilings, handles, lights, etc. However, there are still some technical instabilities in the molding and processing of automotive plastic parts, and these factors make the processing technology of automotive plastic parts unable to play its due level. In the process of automobile plastic parts production, relevant personnel should combine the actual production situation to find out the problems existing in the actual product processing process, and then summarize and analyze, to determine the practical strategy for future industry development.
