【Technical notes】Strength analysis of a hard capsule
2021.02.09
The hard capsule has a hook-type snap-fit mechanism to keep the cap and body from separating. Therefore, the cap and body will be deformed and stressed when fitting. These vary depending on various factors, such as the material and thickness of the hard capsule and the shape of the snap fit mechanism. In this case, by simulating the insertion and removal of the cap, the stress changes in details that are difficult to confirm in an experiment are evaluated graphically, and the force required for the insertion and removal is evaluated.
This solution will help you better solve below problems during your development:
- Predict capsule's strength
- Prevent capsules from cracking or chipping during the filling process
- Evaluation of sealing performance after filling
- Examination of capsule shape that is easy to fit and does not come off easily
