The central feeding system is specially designed for the production of plastic products in the plastics industry. It can realize the continuous unformed continuous forming operation of the whole plant, and can complete various processing techniques such as feeding, dehumidification, drying and coloring, which can not only effectively improve Work efficiency, reduce labor, and improve product quality, which is very popular among users. Here, Nigars introduces the plastic forming method of the central feeding system. 1. Blow molding: Blowing (expansion film) plastic (or hollow blow molding) refers to the molding of a hot thermoplastic preform or sheet in a closed mold by means of fluid (compressed air) pressure into a hollow product. method. Such as various industrial parts, daily-use products, double-wall box-shaped products and front spoilers for automobiles, belt covers, instrument panels, air-conditioning ventilation pipes, etc. The materials processed by blow molding have evolved from household plastics to engineering plastics, and blow molding has become one of the important molding methods in plastics processing. 2. Extrusion molding: A method in which a plastic is continuously passed through a die in a flowing state by heating and pressurizing in an extruder. It is generally used for the forming of sheets, pipes, monofilaments, flat wires, films, wires and cables, etc. It has a wide range of uses and high output. 3. Foaming molding: Refers to the processing method of adding a suitable foaming agent to the foaming material to produce a porous or foamed product. Foamed products have the advantages of low relative density, high strength, low raw material consumption, sound insulation and heat insulation; foaming materials are PVC, PE and PS; products are film, sheet, pipe and profile; foaming can be divided into Chemical foaming and physical foaming. 4. Injection molding: A method in which plastic is first melted in a heating cylinder of an injection molding machine, and then a reciprocating screw pushes the melt into a cavity of a closed mold. It can not only produce high-precision, high-quality products under high productivity, but also has many varieties of plastics that can be processed. The output is large (about 1/3 of the total amount of plastics) and the use is wide. Therefore, injection molding is important in plastic processing. One of the molding methods. The above is about the plastic molding method of the central feeding system, I believe everyone has already understood. Plastic processing occupies a large proportion in industrial production, and the market demand is large. The application of the central feeding system can provide a variety of feeding processing methods, with high efficiency and good effect, not only saving costs, but also effectively increasing production, bringing a lot of enterprises. benefit.
