PURPOSE: A manufacturing method for high density blocks in exact standards is provided to manufacture products in large quantities by heightening strength. CONSTITUTION: The manufacturing method for high density blocks in exact standards comprises the steps of: making a tube(2) by forming many outlets to circulate liquid and gas smoothly, placing a compressor on an opening of a steel tube to keep the compression of liquid and gas, sealing up the opposite side of the steel tube and forming a nut to fix with a bolt, interposing an elastic rubber tube in an outlet, then binding both edges by a fixing band; fixing a metal mold(1) on the middle of a metal mold or the necessary site using a fixing bolt and a fixing nut; after placing materials, restricting and closing all sides of the metal mold(1); keeping the pressure of the tube until being plastic by injecting high hydraulic pressure, air pressure or water pressure using a compressor of a tube(2) provided with the metal mold(1); removing the tube and the metallic mold; and grouting in the space where the tube is removed.
