1. The manufacturing process of plastic products is the molding process of plastic bottles, which refers to the process of making the ultimate plastic products from the polymer manufactured by the synthetic resin factory.

2. processing methods (and a plastic processing) include: pressure molding (molding), extrusion (extrusion molding), injection molding (injection molding), blow molding (hollow molding), calendering, etc.Specific manufacturing process:

⑴ pressure molding: molding or pressing molding.It is mainly used for molding thermosetting plastics such as phenolic resin, urea-formaldehyde resin and unsaturated polyester resin.

⑵ extrusion: extrusion molding, is the use of extrusion machine (extruder) will be heated resin continuous through the mold, extrusion required shape of the product method.Extrusion is also sometimes used in thermosetting plastic molding, and can be used in the molding of foam plastics.The advantage of extrusion is that it can extrude various shapes of products, high production efficiency, automatic and continuous production;The e disadvantage is that thermosetting plastic rope can not be widely used in this method of processing, product size easily produce deviation.

⑶ Injection molding: injection molding.Injection molding is the use of injection molding machine (or injection machine) to thermoplastic rope melt under high pressure into the mold after cooling, solidification to obtain the product method.Injection molding can also be used for thermosetting plastics and foam plastic rope molding.Injection molding has the advantages of fast production speed, high efficiency, automatic manipulation, and can shape complex parts, especially suitable for mass production.The disadvantage is that the cost of equipment and mold is high, and the injection molding machine is difficult to clean up.

⑷ blow molding: hollow blow molding or hollow molding.Blow molding is a method of blowing hollow products by the pressure of compressed air to make the hot resin billet closed in the mold. Blow molding includes two methods of blow molding film and blow molding hollow products.With blow molding method can produce film products, a variety of bottles, barrels, POTS and children’s toys.

⑸ Calendering: It is a molding method in which resin and various additives are processed (kneading, filtering, etc.) into films or sheets through the gaps between two or more opposite calendering rollers of the calender, which are then peeling off the roller of the calender, and then shaped by cooling.Calendering is mainly used in polyvinyl chloride resin molding method, can produce film, sheet, plate, artificial leather, floor tiles and other products.
