The important role of screen changer in plastic processing

China's plastic machinery started in the late 1950s. With the development of China's petrochemical industry, China's plastic machinery industry has gradually formed an independent industrial sector and has begun to take shape. China has become the world's largest country in the production of plastic machine parts.

China’s plastic machinery market has attracted more and more attention from foreign companies. On the one hand, many large international companies continue to increase the depth and breadth of cooperation with Chinese plastic machinery companies, but more often they adopt mergers or purchase shares to occupy the Chinese plastic machinery market . Foreign companies such as Demag, Cornell, and Hong Kong Chen Hsong have entered the Chinese market through joint ventures with domestic companies or the establishment of separate subsidiaries or representative offices.

In recent years, the plastic machinery industry has developed rapidly. The number of plastic machinery manufacturing enterprises in the country has grown to more than 1,000, but there are about 400 enterprises with a certain scale and strength. China's plastics machinery industry has achieved leapfrog development after the Tenth Five-Year Plan. The scale of the industry has expanded. The main economic indicators have increased year by year for eight consecutive years. Its development speed and main economic indicators have been among the best among the 194 industries under the jurisdiction of the machinery industry.

The good development prospects of the plastics processing industry will still be the source of the rapid development of China's plastics machinery manufacturing industry. That is to say, the development potential of China's plastics machinery industry is very large, and the stamina is sufficient, especially some high-tech content, good performance, and price Relatively moderate models, such as extra-large, precise and special injection molding machines, low-temperature, high-power single-screw extruders, multi-layer co-extrusion blow molding machines for the production of packaging materials with high barrier properties and heat resistance. The production of blow molding machinery for industrial parts (auto parts, etc.) has a good development prospect.
