With the development of China's petrochemical industry, automobile industry, packaging industry, chemical foreign trade and other industries, the development of plastic industry is growing rapidly. After the great leap forward development of the tenth five year plan, it is considered that China's plastic industry has become a "sunrise industry" in the Eleventh Five Year plan of the national plastic industry.

Dalian hollow molding mainly analyzes the technical development, application and development trend of hollow products of plastic hollow container molding technology above 50L in China. Jingye machine is always a leading enterprise in the industry in terms of sports cup production equipment. It provides a complete set of mature technologies from scheme design, machine manufacturing, mold processing, process commissioning and production, and can customize production according to customers' personalized requirements. The products produced by the equipment of Jingye machinery are crystal clear, bright and clean, and high-end quality, which can meet the high requirements of the market for such products.

Most thermoplastics can be used for blow molded products, among which high-density polyethylene is the most used. Hollow forming is to expand and deform the high elastic molten plastic parison under the action of compressed air, and then obtain small-diameter mesoporous products through cooling and shaping.

Blow molding film is the most widely used process in the production of plastic film. Plastic molding is to turn plastics into useful products that can maintain their original properties. Before plastic molding, first determine the function and performance index of the product, then select the appropriate material, and then determine the molding process.
