China's plastic industry (rotational molding products) is a "sunrise industry" integrating plastic synthetic resin, additives and additives, plastic processing machinery and molds with plastic processing as the core. The industrial scale is expanding, the product output is increasing year by year, the main economic and technical indicators are increasing significantly, and the whole industry is growing. It is moving forward along the road of realizing the sustainable development of plastic and mold industry from a big country to a powerful country.

Plastic (rotational molding) is an application that can be realized in the development of modern economy, especially in automobiles "As an important material for reduction, reuse and recycling, its processing and molding is a process of pollution-free emission, low consumption and high efficiency. Most plastics can be recycled after use. It is a typical resource-saving and environment-friendly material. According to Luo Baihui, head of the International Association of mold and plastic suppliers, China's automobile industry is an important pillar of the national economy In the production of auto parts, plastics has entered the ranks of the world's advanced countries in terms of the production of plastic raw and auxiliary materials, the overall level of processing equipment and technology, and the depth and breadth of research, development and application of plastic products. Since entering the 21st century, it has made remarkable achievements and achieved a historic leap, Especially after the introduction of the automobile industry plan, a large number of high-quality plastic auto parts are needed, and the development prospect of automobile plastics is promising.
