Molded parts can shrink after they come out of the mold as the polymer cools. The best gates, or openings, for molten plastic to enter the mold are hot runner molds, full-round runners, or modified trapezoid runners. Proper positioning of the gate, or mold opening, and proper mold design can minimize flaws.
