What is the principle of automatic vacuum blister molding production process?

I think everyone is right.The principle of automatic vacuum plastic forming production processI don't know much about it. Today, I 'd like to introduce it to you,The principle of automatic vacuum blister molding production process and the main quality problem solving method~! Let's read this article with Xiaobian!

The basic principle of the full-automatic high-speed plastic forming machine is as follows: the rolled sheet is pulled into the electric furnace oven and heated to a softened state, then pulled to the top of the plastic forming mold by heat, the mold is moved up and vacuumed, the softened sheet is adsorbed to the surface of the mold, and cooling water is sprayed on the surface of the formed sheet in mist form to harden it, and the formed sheet is automatically pulled to the storage box, the pneumatic cutter separates the formed sheet from the unformed sheet, completing the entire process. Most of the main quality problems of blister products occur in the following processes:

1. Blister is not in place, refers to the shape deformation, no blister into the same shape as the mold products;

2. Excessive plastic absorption means that the product is too thin; 3. Pull wire means that there are undue line marks on the formed product;

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