In recent years, China's plastic machinery industry product types are developing with each passing day. Which produced more manufacturers of injection molding machine, according to incomplete statistics has more than 60. From the processing of finished products, there are monochrome, two-color, general and precision plastic products, the main products of these products have their own series, each with its own characteristics.

In the domestic plastic machinery product composition, injection molding machine accounted for the main share, followed by extruder and blow molding machine. In 2000, the output of the domestic injection molding machine was 29311 units, the extruder was 7784 units, the blow molding machine was 1425 units, and the number of injection molding machines and extruders was close to 4: 1. The output value of the three categories was 4.025 billion yuan and 2.533 billion yuan respectively And 433 million yuan, accounting for the industry's total output value of 47.19%, 29.70% and 5.19% .This indicates that the structure of the domestic plastic machinery products are becoming more balanced and reasonable.

From the current product export structure point of view, the injection molding machine accounted for the main share of 60.4%, extrusion unit accounted for 6.8%, hollow molding machine accounted for 11.7%, other plastic machinery accounted for 21.1% .In recent years, domestic injection molding machine market large, The rapid development of injection molding machine, the current domestic plastic machinery industry to the domestic market to provide mass clamping force in the 25000KN following injection molding machine, four-cylinder direct injection molding machine.

According to the production process of plastic products, plastic machinery can be divided into plastic compounding machinery, plastic molding machinery, plastic secondary processing machinery and plastic processing auxiliary machinery or equipment and other four categories. Plastic compounding machines are used in the manufacture of various forms of plastic compounds, including kneaders, presses (refiners and mixers), pellets, screening machines, crushers and grinding machines. Plastic molding machinery, also known as plastic processing machinery for plastic semi-finished products or products molding, including compression molding machines, injection molding machines, extruders, blow molding machines, calendering machines, rolling presses, foaming machines and so on.
