Process method in the life of plastic bottles


Author: mgg-Plastic bottle manufacturer

   Plastic bottles are in the process and method of production process: including extrusion, injection molding, blow molding, calendering, fitting, casting and other ways. Plastic bottles are transmitted, blow molded, plastic heat and melting, then press into a special blow mold and internal air pressure, pressure, molding, forming the shape of the final product, because the shape of the bottle is the shape of the shape of the bottle itself. Inside, when the heating temperature reaches a certain degree, the plastic is soften, and the pressure resistance is small, so the bottle will become smaller and smaller. In a certain processing characteristic and the plastic bottle produced, and ensure that the quality and performance of production and processing are well used.

There are some plastic bottles in different aspects of processing characteristics:   First: High Contraction Rate Enhances the small plastic compromise compromised in plastic, which is mainly composed of heat shrinkage and chemical structures. The first factor affecting the variety of shrinkage plastics. Compared to ordinary epoxyphenol resins, epoxy phenolic resins, unsaturated polyesters, etc., a minimum shrink unsaturated polyester material, such as contraction plastic parts shape and thickness, large thick walls such as plastic and glass The fiber filling contains a small volume shrinkage, and the volatile difference is also very suitable for large contraction, forming pressure, volume shrinkage, compromise compromised, lacking large curing shrinkage peeling.

It will affect the use of plastic bottles. In order to reduce and prevent shrinkage, it is an important factor in atrophy. It affects the actual use effect. Second: Liquidistic plastic bottle is relatively general pressure, and the liquid resin of the plastic material is easily lossed by excessive accumulation and glass. The formation pressure and temperature will increase significantly, the fluidity is affected by many factors, and the liquidity of certain materials must be evaluated, and it is necessary to analyze the factors affecting liquidity.
