How to judge the pros and cons of blister products?

Any machine is not always perfect, vacuum forming machine is not exceptional also, blister molding machine may in some cases, the production of the products is not zero defects. So how to product the discriminant? From the several aspects to proceed with cutting. 1. Crystal: crystal is a kind of unhealthy phenomenon. Refers to the products come out or raw materials with a transparent dots, when materials or manufactured products out there one transparent dots, represents bad raw materials or finished goods. 2. Drawing, drawing is a bad actually a blister products. And it is very serious quality problem. Specific refers to blister product lines on the arch to the grain, the slot between the slot and a thread connected together. 3. Water lines: refers to the blister sheet production into the process of blister packaging, because of different materials and processing technology, make the finished goods like water at the surface of the corrugated, it especially in a transparent blister die test appeared in the process of production, this situation is very common, but if when water ripple obviously is very big, and a lot of time, it is also seen as the product is unqualified, but most of the PVC have phenomenon of water ripple. 4. Scratch: this is bad phenomenon among them one, also in blister packaging products more difficult to prevent a bad phenomenon. This kind of situation will also caused a lot of suction SuChang scrap rate. Specific refers to the blister products surface is scratch presents obvious traces, called scratch. 5. Suction does not reach the designated position, also belong to one of the undesirable phenomenon. Refers to the production of finished goods is not only just like physical model can be configured in, for example was rectangular, because smoking does not reach the designated position became half round corner. The blister packaging is not available.
