PCT No. PCT/JP91/00337 Sec. 371 Date Nov. 13, 1991 Sec. 102(e) Date Nov. 13, 1991 PCT Filed Mar. 13, 1991 PCT Pub. No. WO91/13745 PCT Pub. Date Sep. 19, 1991.A method of detecting the filling weight for an injection molder, or specifically to a method of detecting the weight of the plasticized synthetic resin injected from the injection molder cylinder to fill the cavity of a mold. The object is to ensure highly accurate detection of the filling weight on the injection molder side, in continuous molding production. The weight of the resin injected from the cylinder to fill in the cavity is detected through operations on the basis of the positional values of the screw and the pressure and temperature valves of the resin obtained before and after injection, with the resin pressure maintained at a specified value and with the block valve and check valve closed.
