Tablets are the mainstream dosage form in today's medicines, with the characteristics of accurate dosage and convenient carrying. The packaging forms of tablets include blister, bag, bottle, etc. Among them, tablet medicine bottle is the more commonly used one. The commonly used processing techniques include the following:
Injection blowing: a processing method that combines injection molding and blow molding. Plastic bottles are formed from raw materials to finished products at one time, with a high degree of automation, which is suitable for the production of high-end and exquisite plastic hollow products.
Injection molding: The injection molding process refers to the process of making semi-finished parts of a certain shape by pressing, injecting, cooling, and detaching molten raw materials. This kind of process adopts automatic production, the product quality is stable, the size is accurate, the application range is wide, and there is no seam.
Extrusion blow: It is the process of extruding the parison through the ring die of the die with an extruder, and then moving the parison into the blow mold to expand into a hollow product. This process is suitable for all kinds of plastics, equipment and The mold is low in cost and can produce special-shaped medicine bottles.
Injection stretch blowing: firstly, the molded blank is injected by the injection molding machine, the hot parison is stretched longitudinally, and then compressed air is passed in to stretch it laterally to obtain a product with the same shape as the mold cavity. This process is generally used for PET tablets and medicine bottles.
The above-mentioned common processing technology for tablet medicine bottles, and plastic bottles processed by different processing methods have their own characteristics. Only by controlling each processing flow can high-quality packaging be produced.
