Molded Threads | Design Tips
Adding threads to your plastic part design
Injection-molded threads allow you the ability to fasten your plastic parts to other components securely with relative ease. While adding molded threads to your plastic part design can increase part functionality, if not carefully designed they can add unforeseen costs into the manufacturing process.
Threads are created from the geometry of the mold cavity. As the molten resin enters the mold and the material cools, it solidifies into the final state forming the details of the internal or external threads.
Molded Threads Represent Undercuts
Undercuts typically require side actions or additional components to the mold in order to capture the detail of the part.
