Technical Guide: Snap-Fit Design for Injection Molding
Designing snap-fits for injection molding is a balancing act between material flexibility and structural integrity. In this episode, we explore the mechanical principles behind successful snap-fit joints and how to prevent common failures like stress whitening and snapping.
Key Highlights:
The 3 types of snap-fits every designer must know.
How to calculate deflection and strain for cantilever beams.
Material considerations: Why POM or Nylon might be better than ABS for clips.
Common design mistakes that lead to mold modification costs.
