Plastic processing technology noun explanation

Plastic bottles molding processing refers to the polymers made from synthetic resin factory final process of plastic products. Processing methods ( Often referred to as a processing plastic) Including the molding ( Moulding) , extrusion ( Extrusion molding) , injection ( Injection molding) , blow molding ( Hollow molding) , rolling, etc. 1. Compression molding mould pressing or forming technology, also known as compression is mainly used for phenolic resin, urea formaldehyde resin, unsaturated polyester resin, thermosetting plastic molding. 2. Extruded extrusion is also called the extrusion molding, is the use of squeeze molding machine, Extruder) Continuous heating of resin through the mould, the method of the shape of the products required. Sometimes do on thermosetting plastic extrusion molding, and can be used for foam plastic forming. Extrusion can be extrusion products of various shapes, the advantages of 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. Injection molding is also called injection molding. Injection molding is the use of injection molding machine, Or the injection machine) Will thermoplastics melt under high pressure into a mold Canon of cooling and solidification get products. Injection molding can also be used for thermosetting plastic and foam plastic forming. 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 cleaning is difficult, etc. 4. Blow molding hollow blow molding is also called the hollow blow molding or shaping. Blow molding is closed by means of the pressure of compressed air to make 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 to produce thin film products, all kinds of bottles, barrels, pot type containers and children's toys, etc. 5. Rolling rolling is to pass through the expected processing (resin and all kinds of additives Kneading, filter, etc. ) By calender after two or more steering instead of rolling roller clearance processed into thin film or sheet, then falls off from the calender roller, then through cooling finalize the design of a forming method. Calender is mainly used in PVC resin molding method, can make film, sheet, plate, artificial leather, floor tile and other products. 6. Bubble forming foam materials ( PVC, PE and PS, etc. ) Add the appropriate foaming agent, make plastic produce microporous structure of the process. Almost all thermosetting and thermoplastic plastics can be made into foam. According to the bubble pore structure are divided into hole foam ( Sleep most of the air hole connected to each other) And closed-cell foam ( Most of the porosity is separated from each other) , mainly by the manufacturing methods ( Divided into chemical foaming, physical foaming and mechanical foaming) A decision.
