Blister application

1. Pallet: It is often used for product turnover and transportation. It is suitable for mechanization and automatic packaging, which is convenient for modern management, saving manpower and improving efficiency.


2. Blister box: It can be directly used for the outer packaging of products to enhance the sales competitiveness of products. Common packaging methods are: card blister, heat blister, high frequency blister, double blister, three pairs of blister and so on.


It is produced by automatic high-speed plastic forming machine. The basic principle is: pull the rolled sheet into the oven to heat it to soften state, then pull it to the top of the plastic mold by heat, move the mold up and vacuum, it will soften. The sheet is adsorbed to the surface of the mold, and the cooling water is sprayed on the surface of the formed sheet to be hardened, and the formed sheet is automatically pulled to the storage box, and the pneumatic cutting knife separates the formed from the unformed sheet. Thereby completing the entire process. Most of the main quality problems of plastic products occur in this process: 1. The plastic is not in place, which means that the shape is deformed, and there is no product molded into the same shape as the mold; 2. Excessive plasticity means that the product is too thin; Pulling wire refers to the appearance of undue line marks on the molded product; 4. Uneven thickness. These problems need to be debugged in place after the mold is put in place, including: the advancement time of the sheet, the temperature and time of heating, the strength and time of vacuuming, the position of the upper mold falling, the time and depth, and the placement of the mold in the imposition. Whether to add accessories, etc. between the position and the mold.
