Quality pharmaceutical plastic bottle manufacturer, hurry to purchase MGG solid medicinal plastic bottles, PET pharmaceutical plastic bottles, pharmaceutical plastic bottles, pharmaceutical plastic bottles, affordable, surprises, manufacturers quality assurance, opportunities are rare to buy Purchase Tel: + 86-1591678536 Process and methods of plastic bottles in production process: including extrusion, injection molding, blow molding, calendering, fitting, casting, etc. Plastic bottles are transmitted, blow molded, plastic plus thermal, then pressed into a special blow mold and internal air pressure, pressure, molding, forming the shape of the zui final product, because the shape of the bottle is the external pressure of the shape of the bottle, so the focus is a bottle In itself, when the heating temperature reaches a certain degree, the plastic is soften, and the pressure resistance is small, so the bottle will become less and smaller. In a certain processing characteristic and produced plastic bottle, it is treated according to a certain grade treatment method, and ensuring the quality and performance of production and processing.
Here are some processing features of plastic bottles in different aspects: Yi: High-shrinkage reinforced plastic contraction of small plastic compared to general pressure, which is mainly composed of heat shrinkage and chemical structures. Yi Yi's factors affecting the species of shrinking plastics. Compared to ordinary epoxyphenol resins, epoxy phenolic resins, unsaturated polyesters, etc., a small contraction unsaturated polyester material, such as contraction plastic parts, large thick walls, such as plastic and The glass fiber filling contains a small volume shrinkage, and the volatile difference is also very suitable for large contraction, forming pressure, volume shrinkage, compromise, 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.
