Present situation of plastics technology PP / PE / PC hollow profile sheet extrusion machine
With the continuous development of China's plastic mold processing industry, the processing technology of plastic mold has also been improved. These advances have completely changed the traditional mold design and manufacturing methods, and laid a solid foundation for the further development of China's plastic mold. This paper first analyzes the current situation of China's plastic mold processing technology, and then discusses its future development trend, hoping to provide a theoretical basis for promoting the development of China's plastic mold processing technology. At present, the proportion of plastic mold manufacturing in the whole mold industry is as high as 30%, which shows the importance of plastic mold processing technology [1]. At present, plastic mold has been used in aerospace, instrument and electrical, automobile and other manufacturing industries. Therefore, the plastic mold processing technology has a very good development prospect [2]. Next, the author analyzes the future development trend of plastic mold processing technology based on the status quo of plastic mold processing technology.

1 status quo of plastic mold processing technology
1.1 gas assisted molding technology is becoming more and more mature
In recent years, gas assisted molding technology has been gradually applied in plastic mold processing. At present, some enterprises have applied gas assisted molding technology in the processing of washing machine shell, TV shell, automobile decorative objects and other plastic objects, and achieved very good results [3].

1.2 hot runner technology is widely used
Although the proportion of hot runner plastic mold application is not high, the hot runner technology in the plastic mold processing industry is developing very fast. At present, the application rate of hot runner technology in the plastic mold processing technology has reached 33.33%. The more common hot runner processing technology is divided into three types, namely general internal heating, splitter plate and external heating [4].
1.3 the efficiency of plastic mould is improved
With the introduction of new technology, new technology, the service life of plastic mold has been extended. At present, the processing speed of high-speed plastic profile in China has reached the commercial processing speed. The basic mode of plastic profile can be divided into two modes: double cavity coextrusion and multi cavity coextrusion. More and more enterprises in China have carefully designed the cooling system of the automatic runner mold in the process of plastic mold processing, which has significantly improved the processing efficiency of plastic mold.
