PURPOSE: To realize the molding where the filler is uniformly dispersed in a module cover by injecting the kneaded material of the measured thermoplastic material and the filler into a mold after the melting/kneading and the measurement are made in a heated cylinder. CONSTITUTION: In an injection molding machine 1, the thermoplastic material is fed from a first material feeding part 4 provided at the rear part of an injection molding equipment 2, and the filler is fed from a second material feeding part 7 provided approximately at the center of the injection molding equipment 2. In addition, in the melting/kneading and measurement process of the injection molding, a screw 10 of the injection molding equipment 2 is rotated to transfer the kneaded material to a measuring part 11 at the tip of a heated cylinder 3 while the material is melted and kneaded. In the process to measure the prescribed amount, the feeding of the thermoplastic material and the filler of the following one shot is simultaneously started, and the respective materials are fed at the specified speed so that the ratio of mixture of these materials may be constant, and the feeding is simultaneously completed. |
