Electrically-operated injection molding method

摘要

A die compression injection molding method for an injection molding machine (A) for a precision molding thereof, comprises; (a) injecting weighed resin (3a) into a die cavity (2) of dies (1) in the course of moving in a die closing direction of a movable die (1b); (b) carrying out gate cutting when a specified amount of resin (3) is filled, continuously moving the movable die (1b) in the die closing direction to a specified position, (c) keeping the dies clamping with holding pressure at said specified position during the holding pressure process and the cooling process, (d) after said cooling process, removing the molding from the open dies (1).
