The cull-less molding concept is a new concept of molding to reduce compound usage. The molding compound will be transfered by plunger into the runners and later pushed by guided inert gas into the cavities. Actually the compound wastage in culls and runners are high because there is some of the compound re- maining in the culls and runners. In fact they are fully filled with compound.
