How to Prevent Voids in Plastic Parts?
There are many factors that can cause voids or depressions in plastic parts, but the most common culprits are air bubbles, foreign objects, and manufacturing inconsistencies. To prevent these problems, follow these guidelines:
1. Pre-heat the part to a temperature above the melting point of the plastic. This will help to eliminate any air bubbles that may be present.
2. Inspect the part for any foreign objects before heating it. If you find any, remove them with a sharp knife or pliers.
3. Use consistent manufacturing techniques throughout the process of making the part. This will help to avoid inconsistent pressing and molding which can lead to voids.

Conclusion
If you are noticing voids or bulges in plastic parts, it is likely due to a number of factors. One potential cause could be the use of low-density polyethylene (LDPE), which has been known to cause these types of problems. In order to avoid this issue, make sure that you're using high-density polyethylene (HDPE) instead. Additionally, make sure that the part is properly sealed and that no air pockets exist inside the part. Finally, inspect the molding process closely for any possible mistakes or defects that could be causing these issues.
