The separative force exerted against mold sections 10,12 during injection molding of a plastic product is reduced by injecting plastic material continuously from a gate 30 into a mold cavity 16 having flow channels 19 extending through the cavity region until the mold cavity is filled with said injected plastic material, with said injection being under such conditions of injection pressure, mold cavity temperature, flow channel length, distance between flow channels, flow channel thickness and wall thickness in a thin-cavity region between flow channels and initially injected plastic material solidifies in the thin-cavity regions to thereby reduce said separative force. |
