What is the principle of the fully automatic vacuum forming process?

   Presumably everyone is not very familiar with the principle of the production process of fully automatic vacuum plastic molding. Today, the editor of this website will introduce to you the principle of the production process of fully automatic vacuum plastic molding and the main quality problem solutions~! Let's read this article with the editor!

    The basic principle of automatic high-speed blister molding machine production is: pull the rolled sheet into the electric furnace and heat it to a softened state, then pull it to the top of the blister mold by the heat, move the mold upwards and vacuum, and the softened sheet The material is adsorbed to the surface of the mold, and cooling water is sprayed on the surface of the molded sheet to harden it. The molded sheet is automatically pulled to the storage box, and the pneumatic cutter separates the molded and unformed sheet. Complete the entire process. The main quality problems of blister products mostly occur in the following processes:

    

     1. Insufficient blister means that the shape is deformed and there is no product that is blistered into the same shape as the mold;

 

     2. Excessive blister means that the product is too thin; 3. Pull line means that there should be no line marks on the molded product;

 

     4. Uneven thickness. These problems need to be adjusted in place after the mold is installed, including: the time of sheet advancement, heating temperature and time, the strength and time of vacuuming, the position of the upper mold falling, time and depth, and the placement of the mold in the imposition Location, whether to add accessories between the molds, etc.
