Plastic injection molding is an injection molding forming method. Its device called the plastic injection molding machine, referred to as the injection molding machine. Plastic injection molding machine is the main forming equipment make thermoplastic and thermosetting plastics to all kinds of plastic products. Ordinary plastic injection molding machine is the most widely used, the processing of thermoplastic plastics single screw or horizontal, vertical or angle plunger type single-stage injection molding machine.
While other types of injection molding machine such as a thermosetting plastic, structural foam, multicomponent, reactive, exhaust type injection molding machine, refers to the processed material and machine structural features and common plastic injection mold has a larger difference between some of the injection molding machine. At present, about 30% of the world's plastic raw materials for injection molding, and injection molding machine account for about 40% of the total production of plastic machinery, and has become the plastics processing and plastics machinery industry is an important part of plastic machinery products, is one of the fastest growing, varieties of different specifications, producing the largest number.
In the plastic extrusion equipment, plastic extrusion machines are usually referred to as the host, and its supporting follow-up equipment plastic extrusion forming machine is referred to as auxiliary. Plastic extrusion machine after 100 years of development, from the original single screw twin-screw, derived from multiple screw, and screw and other models. Plastic extrusion machine ( host ) with pipe, film, bar, monofilament, Biansi, packing belt, squeeze net, plate (sheet) material, profile, granulation, coating all kinds of plastic molding auxiliary cable match, composed of a variety of plastic extrusion production line, the production of various plastic products. Therefore, the plastic extrusion machinery whether now or in the future, are widely used in plastics processing industry is the one.
Blow molding machine is composed of two basic steps: forming first parison, with compressed air ( with a tension bar ) to radial inflation ( and axial tensile ) parison, so close ( tensile ) blow mold cavity, the mold cavity in the shape and dimension of gift products, and cooling. According to the parison molding method, blow molding machine for extrusion blow molding and injection blow molding two categories; extrusion blow molding equipment ( especially molds ) cost and low energy consumption, large volume container can be molded and shape complex products; injection blow molding container, have higher size accuracy, do not form a joint, do not generally have a trim.
