A resin detection system for closing an automated valve to prevent resin entering a vacuum line portion of an outlet line is described. The resin detection system comprises a support (300) to a pneumatically-actuated device (320), a capacitive sensor (380) and a valve (410) are mounted. The sensor is configured to provide at least one signal indicative of the presence of resin in the outlet line which is used to close the valve automatically once the presence of resin is sensed by the capacitive sensor. The resin detection system forms part of an injection moulding apparatus and receives signals from a processor thereof to ensure that, if too much resin is injected, the valve is automatically closed even in the event that the sensor does not detect the presence of resin in the outlet line.

A method of diagnosing a state of at least one component of a molding machine is performed such that a state of the at least one component is determined on the basis of a vibration measured at the molding machine. A drive unit of the molding machine accelerates and/or decelerates at least one movable element provided at the molding machine in such a way that the vibration is stimulated in a predetermined frequency range.

An injection molding machine is provided with a selection unit which selects an operation mode from among a plurality of operation modes, a condition acquisition unit which acquires a present condition of the injection molding machine or of peripheral equipment of the injection molding machine, and a determination unit which, based on the selected operation mode and the present condition, determines whether or not manipulation in the operation mode is executable using a plurality of operation initiation conditions pertaining to the operation mode. The injection molding machine is also provided with a display control unit which, when the manipulation in the operation mode is not executable, causes interrelationships between the respective operation initiation conditions pertaining to the operation mode to be displayed in a prescribed display mode on a display unit.
