Understand plastic injection molds for automotive interior and exterior trim

With the advent of the era of electric vehicles, driverless technology and new energy vehicles, the lightweight design of automobiles will be an inevitable trend in automotive design, and it is inevitable that plastics can turn lightweight design into reality. The extensive use of plastics in the automotive industry will surely bring a new historical opportunity to the plastics industry and the automotive injection mold industry.

In October 2016, the China Society of Automotive Engineering released the "Energy-saving and New Energy Vehicle Technology Roadmap". The road map points out that it is expected that by 2020, 2025, and 2030, the quality of the entire vehicle will be reduced by 10%, 20%, and 35% respectively compared to 2016. It is expected that the automotive industry will become the fastest growing field of plastic consumption in the next few years. The rapid development of the amount of automotive plastics will inevitably promote the rapid development of the automotive injection mold industry.

The proportion of interior and exterior of automobile injection mold

Behind the rapid development of the automobile industry is the development of the automobile mold industry. Especially in recent years, the development of the world's automobile mold industry has been changing with each passing day, and the demand for molds in automobiles has also increased. In a new car, about 500 sets of automobile injection molds are needed. In developed countries in the automotive industry, the market share of automotive products has exceeded 60%, and this trend continues to rise. It can be said that injection molds account for a large proportion of automobile molds, and the importance is self-evident.

Advanced technology of automobile interior and exterior injection mold

There is no essential difference between automobile injection molds and other injection molds, but they also have many characteristics of their own. As the added value of automotive injection molds is generally high, many advanced technologies (such as sequence valve hot runner control technology, internal parting surface technology, low pressure injection molding technology, etc.) are first developed and applied in automotive injection molds.
