Plastic processing of six kinds of craft process is introduced

Since entering the China market, plastic bottle, with its light weight, convenient carrying, not afraid to fall, with acid and alkali resistant properties of various characteristics of the widely popular among dealers and consumers, thus rapid root packaging world plastic bottles in just a few decades. By now, plastic has become an important part of living. Cosmetic, food, pickles, honey has been covered in plastic industry, even the farming, animal, medical packaging also gradually be plastic bottles of monopoly. But do you know how to be made of plastic bottles is? Plastic bottles is one part of the rubber and plastic industry, whether it is what kind of plastic bottles, after forming. Plastic forming process is phenolic resin, urea formaldehyde resin, unsaturated polyester resin process of plastic products such as polymers. The plastic processing methods including molding, extrusion, injection molding, blow molding, calendering, etc. Next we detail its processing method for you. 1, compression molding plastic processing method is also called the molding in the industry, used for phenolic resin, urea formaldehyde resin, unsaturated polyester resin, thermosetting plastic molding is the first step in the plastic processing technology. 2, extruded extrusion is also called the extrusion molding, will squeeze molding machine is used to heat the resin continuously through the mould, the method of the shape of the products required. It has the advantage of extrusion products of various shapes, high production efficiency, can be automated, continuous production. Defect is thermosetting plastic can not be widely adopted processing, easy to produce deviation in dimension. 3, plastic injection molding can also be called injection molding. Injection molding is the use of injection molding machine will thermoplastics melt under high pressure into a mold Canon of cooling and solidification get products. Injection molding is the advantage of production speed, high efficiency, operation can be automated, to forming of complex shape parts, especially suitable for mass production. Defect is equipment and mould cost is high, the injection molding machine is not easy to clean. 4, blow molding, blow molding, also called hollow blow molding. Mainly by means of compressed air pressure in the closed in the mold of hot resin parison swell as a method of hollow products, blow molding, including blown film and two methods of hollow blow molding products. By blow molding method is mainly used for production of film products, all kinds of bottle, barrel, kettle capacity etc. 5, rolling rolling it is resin and all kinds of additives, the expected after processing by two or more calender to instead of the calender roll gap processed into thin film or sheet, then falls off from the calender roller, then through cooling finalize the design of a forming method. Rolling PVC resin is the main forming methods, is a thin film, sheet, plate, a major means of artificial leather, floor tile and other products. 6, foaming molding in adding proper foaming agent, foaming material make plastic produce microporous structure of the process. According to the bubble pore structure is divided into hole foam and closed-cell foam, this is determined by the manufacturing method.
