This is an introduction to the Snap-Fit Design Manual.
This manual serves as a guide for designing snap-fit assemblies using thermoplastics. It covers the benefits of snap-fits, such as cost-effectiveness and environmental friendliness, and details the ideal materials like Ultramid and Ultradur resins provided by BASF. The document explains how to balance assembly integrity with beam strength to prevent failure.
Thermoplastics are the ideal material because they have high flexibility and can be easily molded into complex geometries.
Under normal 50% relative humidity conditions, the stiffness and retention force reduce while the deflection increases.
To convert pounds to kilograms, you multiply the English value by 0.4536.
