description PURPOSE:To improve effectively and swiftly a sink and shrinkage quantity. CONSTITUTION:An injection device M is constituted so that it performs repeatedly a molding cycles performing dwelling after molten and kneaded resin is filled into a cavity 1a of a clamped mold 1. A control device 10 is provided with a setting monitoring part 10a, control operation part 10b and control part 10c. The control operation part 10b transmits a mold temperature TW measured by a mold temperature sensor 2 and a heating cylinder temperature TR measured by a heating cylinder temperature sensor 4 to the setting monitoring part 10a by receiving those in the latest molding cycle and in relation to a fixed heating cylinder temperature increment DELTATR, a fixed mold temperature increment DELTATW is operated and an operation value is sent to a control part 10c. The control part 10c raises the heating cylinder temperature TR of the molding cycle continuing to the control part 10c by DELTATR based on the operation value and at the same time the mold temperature TW is lowered by the DELTATW.
