Plastic bottle how to processed

1, compression molding, also calls the cleansing milk packaging or pressure molding, molding 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, is also called the injection plastic injection plastic 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. Say again 4, blow molding, blow molding hollow blow molding or blow molding. 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.
