What kind of defects the blister product have and how to solve it?

Blister products have applications in many aspects. What are the general conditions for the quality of plastic products?


Pulling line: Some undesired line protrusions (not found in the mold) produced during the production of plastic molding, need to re-modify the mold (reduced height and increase the degree of smoothness) and add additional pressure mold (we call it the upper mold) To solve. When the cable is too large, it is regarded as a defective product and cannot be used for high-grade blister packaging. However, in the area of component rotating trays, as long as the cable is arranged neatly and does not affect the function, it should be regarded as a qualified product. Pull lines are also called: La Qiu, cramps and so on.


Scratches: Scratch marks on the transparent plastic blister, especially if the marks are too long or too large, the blister becomes defective and cannot be used for high-grade packaging.


Crystal point: In the production process of plastic sheet, due to the fine dust in the air, it is dropped on the heated plastic material, resulting in a transparent flaw, especially in the production of transparent plastic sheet. If it is too large or too much, it is considered as defective.


Bubbles: In the production process of plastic sheet, the heated plastic material contains air, so that the produced finished product sheet has air bubbles, especially in the production process of transparent plastic sheet, the bubbles are too large, Too much is considered defective.


Water ripple: In the production process of plastic sheet, due to different materials and processing techniques, the finished product sheet surface has surface ripples, especially in the transparent plastic sheet production process. If it is too much, it is considered inferior. In general, the thicker the sheet, the more pronounced the water ripples. Qualified PET materials have few water ripples, but most PVCs have water ripples.


For different plastic products, there will be different problems, such as the card folded blister, the main problem is the back of the fold is not good, will be up. The main problem with folding boxes is that they are not in place, not buckled, etc.


Ditai company now these defects in the blister products. So we will know how to avoid these things happen after making mold!
