The application of plastic molds in the car field is inseparable from the development of the car profession. In recent years, the demand for car professions has been steadily improving, so it has also promoted the rapid development of injection molding plants. In recent years, with the widespread use of cars in family life, the production speed and quality of traditional car plastic shells can no longer satisfy the demand for plastic molds in the car industry.
Plastic molds are classified as consumables, and the general dosage is larger than that of the parts commonly used in cars. More than 90% of the car parts are injection molded with plastic molds, using cold and hot work, plastic shell molds and other technologies. Generally speaking, every 10,000 cars produced by the injection molding plant will consume 0.12 tons of molds. The molds required to make a car are generally not less than 1500, including nearly 1,000 stamping forming molds and nearly 500 interior decoration molds.
Some professional organizations have analyzed that the production demand for plastic molds for cars accounts for nearly 30% of the annual output of injection molding plants. More relevant statistical data show that in 2017, the sales of plastic shells for cars in China reached as high as 66.3 billion yuan. In 2014, the annual output of China’s cars will be as high as 40 million. By then, the annual demand for plastic molds for cars in China will reach about 500 tons.
