Metal processing machine tools are also commonly used for secondary processing of plastics. Plastic secondary processing machinery is used for reprocessing and post-processing of plastic semi-products or products, including thermoforming machines, welding machines, heat sealing machines, hot stamping machines, vacuum evaporation machines, flocking machines, printing machines, etc. Plastic molding machinery, also known as plastic primary processing machinery, is used for the molding of plastic semi-products or products, including compression molding machines, injection molding machines, extruders, blow molding machines, calenders, rotational molding machines, foaming machines, etc. Plastic compounding machinery is used in the manufacture of various forms of plastic compounding materials, including kneaders, plastic mixing machines (open mills and internal mixers), pelletizers, screening machines, crushers, and grinders. Common types are plastic machinery, extruder machine, injection molding machine, film blowing machine, blow molding machine, etc.Īccording to the production process of plastic products, plastic machinery can be divided into four categories: plastic compounding machinery, plastic molding machinery, plastic secondary processing machinery, and plastic processing auxiliary machinery or devices.
Certain general-purpose machinery and equipment such as fluid and solid conveying, separation, crushing, grinding, and drying also occupy an important position in the plastics processing industry, so they are often listed as plastic machinery. The general term for various machinery and devices used in the plastics processing industry.
