Injection molding thermoplastics gives the engineer the ability to mold certain designs to make your product highly functional.
Depending on the result you want from your snap-fit closure, your engineer will help you choose the perfect snap-fit design. The most classic of the snap-fit designs in the classic cantilever.
Simple Cantilever Snap Design
The traditional cantilever design features an arm with a simple hook-like end. This design is particularly effective in instances where you are joining two similar halves, like in housing.
“U” & “L” Shaped Cantilever Snap Designs
Two other subtypes of cantilever snaps are U-Shaped and L-Shaped snap-fit designs. Particularly for thermoplastics, these cantilever designs are preferred. Therefore, depending on the function of the latch, your engineer will often pick on of these three types of cantilever snap design latches.
When it comes to designing, as it applies to thermoplastics, and when considering snap-fit features, radius those edges. We’ve said it before, and we will say it again. When designing a snap-fit feature, you are already trying to find the perfect balance between stiffness and strain. The different cantilever designs, worked out by an experienced engineer, can provide this balance while also choosing the best design option for the function and shape of the part.
Choosing which design to use for your assembled part can be stressful. That’s why our design experts can come up with a solution in a “snap”. This solution requires knowledge and experience of material and thermoplastic design. Here are a few formulas your engineer will consider when designing the perfect snap-fit design for your product.
