WebbFigure 1: Side-action cams are a common solution to small undercuts in injection molding designs. Side-Action Cams The most obvious approach to undercuts is side-actions—mold pieces that act from the outside of the part, moving perpendicular to the direction of mold opening. WebbWhen designing a part, apply as much draft angle as possible—a general rule of thumb is 1 degree of draft per 1 inch of cavity depth, but that can change with the aforementioned factors. Try following these general guidelines: 0.5 degrees on all vertical faces is strongly advised. 1 to 2 degrees works very well in most situations.
