PROBLEM TO BE SOLVED: To provide an injection apparatus in which operation based on malfunction detection is performed adequately.SOLUTION: An injection apparatus 1 includes a sleeve 3 connecting to a cavity 105, a plunger 5 which extrudes molding material (molten metal) in the sleeve 3 to a cavity 105, a drive mechanism (an injection cylinder 9, a hydraulic device 11 and a drive device 13) which can drive the plunger 5, and a control device 153 which controls the drive mechanism. The drive mechanism includes an electric motor 23. The control device 153 performs low-speed injection by driving the electric motor 23, detects a malfunction based on load of the electric motor 23 in a constant speed area (t1 to t2) of the low-speed injection (Step S11 to S13), and, when a malfunction is detected in plural cycles, performs processing of standing a stop flag (Step S16) which is not performed in a case of detecting a malfunction only in one cycle. |
