Driven by the vigorous development of the plastic products industry, China's production and sales of plastic machinery have ranked first in the world. In 2007, the output value of China's plastic machinery exceeded 20 billion yuan. At the same time, the export volume continued to increase, and the growth rate of export was much faster than that of import. However, industry experts pointed out that the structure of China's plastic machinery products needs to be adjusted.

According to the statistics of the General Administration of Customs of China in 2007, the total export volume of plastic machinery in 2007 was 100633 sets (excluding accessories), an increase of 51% over the previous year, and the import volume was 25765 sets (excluding accessories), a decrease of 12%. In terms of quota, in 2007, the export of plastic machinery was 1.45 billion US dollars, an increase of 40% over the previous year, and the import was 2.56 billion US dollars, an increase of 7.2% over the previous year.

From these data, it can be seen that although the quantity of plastic machinery exported in China is nearly four times that of imported products, the value of exported products is only half of the value of imported products (56.7%). This shows that the "gold content" of plastic machinery exported by China is low. At the same time, although the import volume of China's plastic machinery in 2007 decreased by 12% compared with the previous year, the value increased by 7.2%, further indicating that the value of China's imported plastic machinery is relatively high, that is, most of them are high-end products, which cannot be produced in China or the equipment performance cannot meet the requirements.

Therefore, experts pointed out that although the manufacturing and supporting level of China's plastic machinery has been continuously improved through continuous adjustment and development, there is still a big gap between China and the advanced level of foreign countries, especially the high-end products still can not meet the needs, and the product structure needs to be improved.

In 2007, the total export volume of China's injection molding machines was 17577, accounting for 47% of the total export volume of plastic machinery, an increase of 20% over the previous year; The import volume of injection molding machines was 13825, accounting for 74% of the total import volume of plastic machinery, a decrease of 10% over the previous year. In 2007, the export value of injection molding machines was 480 million US dollars, accounting for 58% of the total export value of plastic machinery, and the export value increased by 37%; The import volume of injection molding machines was 930 million US dollars, accounting for 74% of the total import volume of plastic machinery, and the import volume decreased by 5%.

Experts in the industry believe that this is a gratifying change, which shows that China's injection molding machines are moving towards the international market while meeting the domestic market. However, we should also see the gap, especially in the large-scale and high-precision injection molding machines, China still needs to spend nearly US $1 billion a year on imports. Therefore, the plastic machinery industry needs to make more efforts in the research and development of high-end products.

In 2007, the total export volume of China's extruders was 13311, accounting for 35% of the total export volume of plastic machinery; The import volume of extruders is 1574, accounting for 8% of the total import volume of plastic machinery. In 2007, the export value of extruders was 300 million US dollars, accounting for 33% of the total export value of plastic machinery; The import volume of extruders is 270 million US dollars, accounting for 39% of the total import volume of plastic machinery. In 2007, the export volume of extruders increased by 62% over the previous year, and the export value increased by 76%; In 2007, the import volume of extruders decreased by 21% over the previous year, and the import amount decreased by 10%.

Like the injection molding machine, this situation of export growth and import reduction shows that China's extruder industry has made great development, and is gradually replacing imported products, while moving forward to the international market.

In 2007, the total export volume of calenders was 2430, accounting for 6% of the total export volume of plastic machinery; The import volume of calender is 212, accounting for 1% of the total import volume of plastic machinery. In 2007, the export value of calender was 6.73 million US dollars, accounting for 1% of the total export value of plastic machinery; In 2007, the import volume of calender was 41.28 million US dollars, accounting for 2% of the total import volume of plastic machinery. In 2007, the export volume of calender increased by more than 4 times over the previous year, and the export value increased by 25%, indicating that the number of exported products increased but the value was not high; However, the import volume of calender in 2007 decreased by 36% compared with that in 2006, and the import value increased by 29%. On the contrary, the value of imported products was higher.
