Kunshan blow molding processing using a variety of technologies, a variety of materials, there are mainly several:
Polyethylene (PE) Polyethylene is a high yield variety in the plastics industry. Polyethylene is opaque or translucent, lightweight crystalline plastic, with excellent low temperature resistance (the lowest use temperature can reach -70 ~ -100℃), electrical insulation, good chemical stability, resistance to most acid and alkali erosion, but not heat resistance. Polyethylene is suitable for processing by injection molding, blow molding, extrusion and other methods. PE can be divided into low density polyethylene LDPE according to different density; High density polyethylene HDPE; Linear low density polyethylene LLDPE.
Polypropylene (PP) Polypropylene is a thermoplastic obtained from the polymerization of propylene, usually colorless, translucent solid, odorless and non-toxic, the density of 0.90 ~ 0.919 g/cm, is the lightest general plastic, its outstanding advantages are the characteristics of cooking resistance in water, corrosion resistance, strength, rigidity and transparency are better than polyethylene, The disadvantage is poor low temperature impact resistance and easy aging, but it can be improved by modification and addition of auxiliaries respectively. The production methods of polypropylene are slurry method, liquid phase bulk method and gas phase method.
Polyvinyl chloride (PVC) Polyvinyl chloride is a plastic obtained from the polymerization of vinyl chloride, and its hardness can be greatly changed by adding a plasticizer. It is made of hard products and soft products have a wide range of uses. The production methods of PVC include suspension polymerization, emulsion polymerization and bulk polymerization, and suspension polymerization is the main method.
Polystyrene (PS) Universal polystyrene is a polymer of styrene, the appearance of transparent, but has the drawback of brittle, therefore, by adding polybutadiene can be made into impact resistant polystyrene (HTPS). The main production methods of polystyrene are bulk polymerization, suspension polymerization and solution polymerization.
ABS ABS resin is the product of polymerization of acrylonitrile, butadiene and styrene three monomers, referred to as ABS terpolymer. Due to the different proportions of its components A (acrylonitrile), B (butadiene) and S (styrene) in the composition, as well as the differences in manufacturing methods, the properties of this plastic are also very different. ABS is suitable for injection molding and extrusion processing, so its use is mainly to produce these two types of products.
Injection blow molding is a molding method that integrates the characteristics of injection molding and blow molding products. At present, it is mainly used in blowing beverage bottles and medicine bottles with high precision and some small structural parts.
① In the injection station, the first injection molding embryo, the processing method is the same as ordinary injection molding.
② After the injection mold is opened, the mandrel and the mold blank are moved to the blow molding station.
③ The mandrel places the mold blank between the blow molding molds and closes the molds. Next, compressed air is blown into the mold through the center of the mandrel, blowing it to fit the mold wall, and cooling it.
④ Open the mold, turn the mandrel to the release station, remove the blow molding parts, and then turn the mandrel into the injection station for circulation.
