Abstract
A low-pressure screw in-line type injection molding method and apparatus for use with materials such as urea mixed resin powder are disclosed. The initial injection is performed at a converted injection pressure in the range of 250-700 Kg/cm.sup.2 and at an injection velocity in the range of 30-50 mm/sec. When the mold cavity has become nearly completely filled, the converted injection pressure is lowered to 50-200 Kg/cm.sup.2 for the completion of the injection cycle under low pressure conditions.
