Manufacture Of Plastic Parts Manufacturing

    Divided into four categories: 1, extrusion: plastic processing, also known as extrusion, non-rubber extrusion machine in the use of hydraulic pressure in the mold itself, said extrusion out of pressure. Refers to the material through the extruder barrel and the role of the screw, while by the thermoplastic, while the screw forward, continuous through the nose and made a variety of cross-section products or semi-finished products, a processing method. 2, injection molding: also known as injection molding, it is a injection molding and molding method. The advantages of injection molding method is the production speed, high efficiency, the operation can be automated, color varieties, the shape can be from simple to complex, size can be large to small, and the product size is accurate, easy to replace the product, can form complex Parts, injection molding for a large number of production and shape of complex products such as molding processing.Plastic Parts Manufacturing

    1. The manufacturing process of plastic products, that is, the molding process of plastic bottles, refers to the synthetic resin factory made of polymer made of the final plastic products process. 2. Processing methods (and plastic processing) include: compression molding (extrusion molding), extrusion (extrusion), injection molding (injection molding), blow molding (hollow molding), rolling and so on. Detailed manufacturing process: compression molding: molding or pressing molding. Compression is mainly used for phenolic resin, urea-formaldehyde resin, unsaturated polyester resin and other thermosetting plastic molding. Extrusion: Extrusion is the use of an extruder (extruder) to continuously heat the resin through the mold, extrusion of the desired shape of the product. Extrusion sometimes also thermosetting plastic molding, and can be used for foam Of the molding. Extrusion is the advantage of extruding a variety of shapes of products, high production efficiency, can be automated, continuous production; the disadvantage is that thermosetting plastics can not be widely used in this method of processing, product size prone to bias. Injection Molding: Injection Molding. Injection molding is the use of injection molding machine (or injection machine) will be thermoplastic melt under high pressure into the mold by cooling, curing the product obtained by injection molding can also be used for thermosetting plastics and foam molding. The advantages of injection molding are production speed, high efficiency, the operation can be automated, can shape the complex shape of the parts, especially for mass production. Disadvantages is the high cost of equipment and molds, injection molding machine cleaning more difficult.Plastic Parts Manufacturing

    Blow molding: hollow blow molding or hollow molding. Blow molding is a method of inflating a hot resin parison that is closed in a mold into a hollow product by means of the pressure of compressed air. The blow molding comprises both blown film and blown hollow product. Film products, all kinds of bottles, barrels, pots and children's toys, such as toys The calendering is the processing of the resin and the various additives by the treatment (kneading, filtration, etc.) and then processed into a film or sheet by the gap of two or more diametrically opposed calender rolls of the calender, followed by peeling off from the calender roll , And then by cooling a molding method. Rolling is mainly used for the molding method of polyvinyl chloride resin, can produce thin film, sheet, sheet, artificial leather, floor tile and other products. Foam materials (PVC, PE and PS, etc.) by adding the appropriate blowing agent, so that the process of plastic microporous structure. Almost all of the thermosetting and thermoplastics can be made of foam. According to the cell structure is divided into open-cell foam (feel most of the pores connected to each other) and closed-cell foam (the vast majority of pores are separated from each other), which is mainly by the manufacturing method (divided into chemical foam, And mechanical foaming).Plastic Parts Manufacturing
