The Way The Blister Packaging Machine Is Formed
Mar 03, 2022
There are two ways to form medicine by blister packaging machine, namely compression molding and blister molding. Compression molding is to use compressed air to blow the softened sheet against the mold to make it close to the four walls of the mold. The mold adopts the shape of a flat plate, which is generally intermittently conveyed, and can also be continuously conveyed. Its molding quality is good, and it is suitable for both deep and shallow bubble caps.
The blister molding of the blister machine is to use the vacuum method to adsorb the softened sheet on the four walls of the mold to form the cavity of the blister. Most of the molds are in the shape of a continuously conveyed drum. Due to the limited suction generated by the vacuum, and the limited angle of the blister from the drum after molding, it is only suitable for shallower blister and thinner materials.
According to the degree of automation, blister packaging machines are divided into three types: semi-automatic style, automatic style machine and fully automatic production line. Because the blister packaging of medicines is produced in large batches, the varieties are relatively fixed, and safety and hygiene are required, it is advisable to use a fully automatic production line for production. During automatic operation, in addition to completing the packaging process, processes such as printing, packaging instructions, and boxing can also be connected to the packaging line to form a fully automated blister packaging production line.
