China's plastic machinery began in the late 1950s. With the development of China's petrochemical industry, China's plastic machinery industry gradually formed an independent industrial sector and began to take shape. China has become the world's largest producer of plastic machine parts, and Ningbo Haitian has become the world's largest producer of injection molding machines.
In recent years, the plastic machinery industry has developed rapidly. The number of plastic machinery manufacturers in the country has grown to more than 1,000, but about 400 companies with a certain scale and strength. China's plastic machinery industry has achieved leap-forward development after the 10th Five-Year Plan, and its industrial scale has expanded. The main economic indicators have been increasing year by year for eight consecutive years. Its development speed and major economic indicators are among the top 194 industries under the jurisdiction of the machinery industry.
The good development prospects of the plastics processing industry will continue to be the driving force for the rapid development of China's plastic machinery manufacturing industry. It is expected that the average annual growth rate of demand for plastic machinery in China will be around 6%, and will reach 14.5 billion yuan in 2010. That is to say, the development potential of China's plastic machine industry is very great, and the stamina is very good, especially some models with high technology content, good performance and relatively moderate price, such as extra large, precision, special injection molding machine, low temperature, high power type. Single-screw extruder for the production of high-impedance and heat-resistant packaging materials, multi-layer co-extrusion blow molding machines, production of industrial parts (auto parts, etc.) blow molding machinery, etc., have a good development prospects .
Five plastic machinery materials
The prices of plastic machinery are very different. The extruder barrels are mainly 48 gauge steel. The price is cheap. The wear resistance is poor. No. 38 Luogang aluminum belongs to the alloy. The high thermal conductivity is good. The traction equipment steel bar mold needs electroplating to increase its hardness. .
