Blown blow molding machine manufacturers talk about blow molding is a common method of manufacturing hollow thermoplastic products, the main products are the barrel and hollow containers. The blow molding machine can plasticize the preformed product by heating, and then enter the mold for blow molding. This method is mainly used for high-speed and high-yield PET bottles and blow molding machines.

BOPP bottle production, that is, two-step process; blow molding can also be combined with injection molding process to become a injection-blow machine, which is also a common method for producing containers in PET; blow molding process can also be combined with extrusion process, extrusion Blow molding equipment has a wider range of applications and can produce more products. The products include multi-layer composite film and various polyolefin hollow containers, which are widely used in the food, pharmaceutical and cosmetic industries.

According 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 equipment. Plastic compounding machines are used in the manufacture of various forms of plastic compounds, including kneaders, refiners (openers and internal mixers), pelletizers, screening machines, crushers and grinders. Plastic molding machinery, also known as plastic one-time processing machinery, is used for the molding of plastic semi-finished products or products, including compression molding machines, injection molding machines, extruders, blow molding machines, calendering machines, rotational molding machines, foaming machines, and the like. Plastic secondary processing machinery is used for reprocessing and post-processing of plastic semi-finished products or products, including thermoforming machines, welding machines, heat sealing machines, hot stamping machines, vacuum evaporation machines, flocking machines, printing machines, and the like. Metalworking machines are also commonly used for secondary processing of plastics. The plastic processing auxiliary machinery or device is used to rationalize the plastic processing process, including automatic metering feeding device, automatic scraping device for corner scraps, automatic take-out device for injection molding products, rapid replacement device for injection molds, injection mold cooler, automatic thickness measuring device and raw materials. Transport and storage equipment, etc. Such auxiliary machinery or devices have become an indispensable part of the automation of modern plastics processing.
