Injection Mold: Outer Ring

Ring Mold Models (molds currently still in production)
Cavity Mold


Core Mold


Diagrams of the outer ring mold are shown above. Potential rework on the ring mold largely centers on the press-fit aspect of the ring size. Because the ring must sandwich the thermoform plastic dome piece onto the yo-yo base, shrinkage and tolerances are the most important factors. Before optimization runs, it will be important to check the fit of the ring over the base/thermoform parts and adjust any features to account for minor changes in the base/thermoform shape or thicknesses.
