In a temperature control device, a resin flow channel is formed from a nozzle section and a cylinder section that is connected to the nozzle section and the device controls the temperature of the resin that flows in the resin flow channel. The temperature control device is provided with: a first temperature sensor for detecting the nozzle temperature of the resin flowing through the nozzle section; a first temperature control unit for performing PID control so that the nozzle temperature achieves a first target temperature; multiple second temperature sensors for detecting the cylinder temperature of the resin flowing through the cylinder section; and second temperature control units for performing PID control so that the cylinder temperature achieves a second target temperature. The second temperature control units perform PID control of the cylinder temperature using temperature control information from the first temperature control unit.

The monitoring unit is for a user to operate to control the extruder, the heating module and the drive unit.

A manufacturing apparatus includes an injection cylinder to which molten resin is supplied and which is configured to inject the molten resin, and an injection plunger disposed such that the injection plunger fits in the injection cylinder and moves in a first direction and a second direction opposite to the first direction. The injection cylinder includes a base body configured to contain the molten resin, and a sleeve configured to be detachably attached to the base body. The injection plunger is configured to be inserted into an inner portion of the base body through an opening portion formed in the sleeve and slide on the sleeve.

A technique for managing a shear heating value of a molding material is provided. A control device of an injection molding machine individually controls outputs of a plurality of heating units for a plurality of zones, respectively, into which a cylinder is divided in a flow direction of a molding material. The control device acquires the output of the heating unit provided in a predetermined zone both in a steady state in which an operation of a screw provided inside the cylinder is stopped and at a time of molding at which the operation of the screw is performed, and calculates a difference in output of the heating unit provided in the predetermined zone between at a time of molding and in the steady state.

An integrally molded body has a rectangular planar structure in which an inner resin material containing a thermoplastic resin is interposed between a plate material having a design surface and an outer resin material containing a thermoplastic resin, the planar structure having a first joint in which at least a partial region of the outer-peripheral-side surface part and/or the outer peripheral edge part of the plate is joined with the inner resin material, and a second joint in which at least a partial region of the outer-peripheral-side surface part and/or the outer peripheral edge part of the inner resin material is joined with the outer resin material.

A method and apparatus for producing hollow articles made of injection moulded plastic material by a mould having a die within which there is inserted a core, and at least one injector including a pin valve displaceable between a closing position and an opening position for injecting the pressurized plastic material into a space comprised between the die and the core. During the injection, any flexural deflection of the core is detected and the pin valve of the or of each injector is displaced in a controlled fashion to adjust a pressure and a flow rate of the injected plastic material, so as to reduce or eliminate such deflection of the core.

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.

In a temperature control device, a resin flow channel is formed from a nozzle section and a cylinder section that is connected to the nozzle section and the device controls the temperature of the resin that flows in the resin flow channel. The temperature control device is provided with: a first temperature sensor for detecting the nozzle temperature of the resin flowing through the nozzle section; a first temperature control unit for performing PID control so that the nozzle temperature achieves a first target temperature; multiple second temperature sensors for detecting the cylinder temperature of the resin flowing through the cylinder section; and second temperature control units for performing PID control so that the cylinder temperature achieves a second target temperature. The second temperature control units perform PID control of the cylinder temperature using temperature control information from the first temperature control unit.
