250ml Blue Plastic Vaccine Vial Laboratory Veterinary Medicine Liquid Vial
Plastic packaging bottles have the advantages of light weight, non-breakable, high cost performance, and are widely used in various industries such as pharmaceutical packaging, daily necessities, and food. In terms of processing methods, extrusion blow molding and injection blowing are the main Injection blowing process, namely injection blowing, is a blow molding method combining injection molding and blow molding. First, the mold with bottom is produced by injection molding, and then the mold is transferred to the blow mold for blow molding. Injection blow molding first is the production embryo. The injection agent will inject the melt into the injection mold with a blowing core tube to form the mold with a bottom, and then transfer to the blow mold at the blow molding station through the mechanical device for blowing. After blowing up the mold, the mold is closed, compressed air is introduced into the mold through the mandrel pores, and the mold is closely fitted with the blow molding cavity under the action of air pressure, and transferred to the release station after cooling; Finally, the product is removed from the mandrel at the release station or directly sent to the packaging post, and then into the next cycle of production.
The plastic packaging bottle produced by this process does not form a joint on the surface, does not need to be trimmed after forming, generally does not produce leftover materials at corners, the finished product wall thickness is uniform, high accuracy, and is suitable for small-capacity plastic bottle processing.
With the continuous progress of science and technology, the processing technology of plastic packaging bottles is also constantly improving, such as the two-step injection and pull blowing process has been gradually replaced by the more advanced one-step injection and pull blowing process, and the quality of plastic bottles will also have a qualitative leap.
