摘要： A removable heating device for a hot runner nozzle contains an elongated heating unit which exhibits at least one longitudinal slot which does not extend as far in the longitudinal direction as the length of a substantially cylindrical heating unit and which enables an enlargement of the inner diameter of the heating unit by its open end. The heating device further has a channel disposed in the outer surface of the heating unit in which an electrical heating element is disposed. Furthermore, a heater/thermocouple assembly contains such a heating device and at least one thermocouple for detecting the temperature in the front end region of the hot runner nozzle.

摘要： A hot runner nozzle assembly includes a nozzle heater, a hot runner nozzle, a nozzle tip, a nozzle tip seal surrounding the nozzle tip and a connecting element positioned to removably couple the tip seal to the nozzle tip and to create a first contact seal between the nozzle tip and the tip seal and a second annular contact seal between the tip seal and a mold component. The nozzle tip is made or shaped via a sintering process from a metal matrix composite (MMC) material having a first coefficient of thermal expansion. The tip seal is made or shaped from a ceramic based powder material, having a second coefficient of thermal expansion that is different from the first coefficient of thermal expansion. In operation this hot runner nozzle assembly provides an improved heat profile and a reduced leakage at the tip area under a wider operating processing window.

摘要： A valve gated hot runner system that includes a single movable plate (or movable frame) that retains multiple valve pins. A linear actuator is coupled to rigid transmission elements that convey a linear motion from the actuator to several rotary components via a direct or indirect contact between at least a portion of the rigid transmission elements and the rotary components. The rigid transmission elements and the rotary components are connected to a common plate. The rotary components are further coupled to the movable plate (frame) and through their full rotation or turning lift or translate the movable plate (frame) with the valve pins to open and close the communication between hot runner nozzles and corresponding mold cavities. The actuator can be electrical, electro-magnetic, pneumatic or hydraulic.
