When Buying Plastic Products, I Found That Some Water Cups Have Uneven Pits on the Surface. What Caused This?

Plastic water cups, especially the lids, often have some uneven dents. What causes this?

From a simple point of view, it is caused by the production process. The mold design of the product does not meet the needs of the process, resulting in uneven pits.

The professional point of view is that during injection molding, there is an unreasonable mold design, which causes the thickness of the plastic material to be too large, resulting in shrinkage and uneven pits. To solve this defect is to adjust the mold so that the thickness of the meat is less than 3 mm, so that the shrinkage phenomenon can be avoided.
