Zusammenfassung:	To provide an injection molding machine that can easily estimate an adhesion amount of deposits in a mold device.SOLUTION: There is provided an injection molding machine 1, comprising: a deposit prediction device; and an injection device 11 that injects a molding material into a mold device 101. The deposit prediction device comprises: a gas analysis unit that analyzes a generated gas caused from the injection device 11 and/or the mold device 101 and measures a generated amount of a material gas derived from the molding material; and a deposit estimation unit that estimates an adhesion amount of deposits in the mold device 101 from the generated amount of the material gas based on material decomposition information regarding a relationship between the generated amount of a non-volatile component and the generated amount of a volatile component when the molding material is heated.SELECTED DRAWING: None 【課題】金型装置内の堆積物の付着量を簡便に推定することができる射出成形機を提供する。【解決手段】この発明の射出成形機１は、金型装置１０１内に成形材料を射出する射出装置１１を備えるものであって、射出装置１１及び／又は金型装置１０１からの発生ガスを分析し、成形材料に由来する材料ガスの発生量を測定するガス分析部と、当該成形材料を加熱した場合における不揮発成分の生成量と揮発成分の生成量との関係についての材料分解情報に基づき、前記材料ガスの発生量から、金型装置１０１内の堆積物の付着量を推定する堆積物推定部とを有するものである。【選択図】なし
