Pharmaceutical plastic bucket molding equipment Development

Pharmaceutical plastic bucket molding equipment Development Status
 
   Injection blow molding machine is mainly used for processing drums HDPE, PP raw materials, medicine bottles. Injection blow molding equipment using small plastic bottles generally welcomed by the pharmaceutical manufacturers. Since the injection blow molding of the bottle during the molding process, the nozzle device can be injection molded bottle, thus ensuring the accuracy of the bottle; followed by the mechanical configuration of the mandrel blow bottle, a plastic bottle is to ensure the dimensions accuracy. Injection blow molding medicine bottles may be used step 2-position or 3-station injection blow molding machine processing. Since the 2-station injection blow molding machine lacks a dedicated off bottles and cooling station, it is difficult to achieve automatic counting packaging, resulting in production efficiency lower than 3 stations.
    Therefore, in the actual production application it is more 3-station machine. The aircraft's three stations to 120 ° angle of an equilateral triangular distribution, the first station for the injection molding station, a second station for the blow molding station, the third station was off the bottle and the cooling station. Three stations can be run simultaneously, high production efficiency, short cycle, may be connected to the conveyor belt automatic counting packaging, pharmaceutical plastic bottles realize the whole production process with the staff of "no contact", thus ensuring clean and hygienic products. Injection blow molding machine not forming complex shapes and molded bottle most of the smaller volume (typically 10 ~ 300ml). However, due to the flatness bottle injection blow molded bottles, the bottle wall thickness uniform, in particular between the bottle and the cap has good sealing performance, and is prevented from being volatilized gases to the outside of the plastic bottle gas drugs bottle permeation performance requirements, so that such bottles fulfill the special requirements of pharmaceutical packaging. State Drug Administration as early as in "during the" proposed by injection blow molding process for the production of high quality plastic bottle. At present, China imported from the injection blow molding medicine bottles more than 40 production lines, with a total production capacity of about 700 million / year.
