Central conveying system is designed for plastic products of plastic industry. It can realize continuous unmanned molding operation in succession, and can finish several processing technologies such as feeding, desiccation, coloring, etc. It not only promotes work efficiency effectively and reduces labor force, but also enhances product molding quality and is well received by users. Do you know the plastic molding method of central conveying system?
Blow molding is a molding method which blows thermoplastic parison or sheet in closed mold to be hollow article by fluid pressure (compressed air), such as various industrial components, household products, dual-wall box products as well as car's front spoiler, belt cover, instrument board, air conditioner pipeline, etc. Materials processed by blow molding are from daily-use plastic to engineering plastics. At present blow molding has become one of the important molding methods for plastic working.
It is a method that plastics continue opening molding in flow condition by heating and pressing during central conveying system. It is generally used in molding of panels, pipes, steel wires, strip yarns, thin film, cladding cables and cords, etc. with wide application and high output.
It is a processing method that adds proper foaming agent into foam materials, and produces porous or foam articles. Foam products have advantages such as small relative density, high strength, less dosage, sound insulation, heat insulation, etc. Foam materials have PVC, PE, PS, etc. Foam products have thin films, panels, pipes, sections, etc. Foam can be divided into chemical foam and physical foam.
Plastic will be softened by heat in heat cylinder of injection molding machine, reciprocating screw pushes melt into mold cavity of closed mold, and then molding forms. Injection molding will not only make products with high precision and high quality, but also has various kinds of processable plastics, large output (about 1/3 of total quantity) and extensive use, therefore, injection is one of the important molding methods of plastic working.
Above contents are plastic molding methods of central conveying system. You may have gained some understanding. Plastic working accounts for large proportion of industrial production, and has great market demands. Application of central conveying system can provide many feed processing methods, with high efficiency and good effect, not only save the cost, but also raise production, and bring the company many benefits.
