Appeal No. 96-3174
Application 07/970,608
(b) injecting into each pre-enlarged mold cavity a
volume of plasticized resin larger than a volume of the
article to be formed but insufficient to fill each pre-
enlarged cavity;
(c) commonly and simultaneously applying a main clamp
force of the injection molding machine before commencement of
said injection to reduce the volumes of the mold cavities and
fill the reduced volume mold cavities while venting gases; and
(d) maintaining the applied main clamp force until a
final clamp lock-up position is reached, thereby compressing
the resin until slight excess is forced into a pressure relief
outlet and the resin solidifies.
