A temperature control system and method for regulating a liquid temperature in a recirculation system of a molding system includes determining an operating pressure of the liquid in the recirculation system, determining an operating temperature of the liquid in the recirculation system, receiving the operating pressure and the operating temperature, comparing the received operating temperature to a threshold temperature as a function of the operating pressure, and adjusting an output of a heat exchanger in the recirculation system when the operating temperature is beyond the threshold temperature.

The present invention offers a technique for providing assistance in setting at least one of the temperature of a nozzle and the temperature of a cylinder. A control device for an injection molding machine includes a monitoring part configured to monitor, during a filling step of filling the inside of a mold device with a molding material, a change in the filling pressure acting on the molding material.

A material delivery device includes: a plasticizing unit including a screw; a nozzle through which a plasticized material is delivered to outside; a communication flow path provided between the screw and the nozzle and through which the plasticized material flows; a pressure detection unit including a first cylinder coupled to the communication flow path, a rod inserted into the first cylinder, and a pressure sensor disposed with the rod separated from the communication flow path, in which the rod is configured to receive a pressure of the plasticized material in the communication flow path at a first end surface facing the communication flow path, and transmit the pressure to the pressure sensor through a second end surface opposite to the first end surface; and a rotation regulation mechanism configured to regulate rotation of the rod about a central axis along a longitudinal direction of the rod by engaging a first engaging portion provided on a side surface of the rod and a second engaging portion to be engaged with the first engaging portion.

A filter device for plasticized molding material includes a filter housing and a filter element arranged in the filter housing. The filter housing has at least two housing elements movable relative to each other. A drive is provided, via which the housing elements are movable between an open position and a closed position. The filter element is at least partially released in the open position of the housing elements and can preferably be taken out of the filter housing.

The disclosure is directed to a side gate nozzle (1). The side gate nozzle (1) usually comprises a supply block (2), a distribution block (3) and a nozzle block (4) inter-connected to each other in an axial direction (z). The nozzle block (4) comprises at least one nozzle recess (5), in which a nozzle insert (6) is arranged. The nozzle insert (6) is in the axial direction (z) held by an individual set screw (7) directly or indirectly interconnected to the nozzle block (4).
