摘要： A heater assembly for an injection molding apparatus comprises a heater sleeve having a threaded inner surface for engaging a threaded outer surface of a nozzle body of a nozzle or a threaded surface of a mold manifold. A clamping element such as a lock nut or a spring is provided adjacent the heater sleeve. The lock nut and/or the spring abuts the heater sleeve to force the threaded inner surface of the heater sleeve into contact with the threaded outer surface of the nozzle body. This removable clamped heater assembly operates regardless of the temperature of heater.

摘要： A sleeve heater has an electrical and generally cylindrical heater coil centered on an axis and shaped to fit over a part to be heated, a radially compressible and generally cylindrical inner sleeve snugly coaxially surrounding the heater coil, and a radially generally inextensible and generally cylindrical outer sleeve fitted coaxially over the inner sleeve. The outer sleeve has an inner surface bearing tightly radially inward on the inner sleeve and radially compressing the inner sleeve and the coil inward. The inner sleeve is formed with two or more axially extending and axially oppositely open slots that are angularly equispaced, with alternate slots open axially in opposite directions.

摘要： In-line valve-gated nozzles for a single or multiple cavity applications wherein a valve-gated hot runner nozzle has a melt channel uniformly heated along the entire path. The valve pin is driven by an actuation device that is located adjacent to the nozzle to regulate the flow of melt. The actuation device has a linear motion and applies a uniform axial pressure on to the valve pin. This valve-gated nozzle can be linked directly to a machine nozzle, to an injection manifold or to a stack mold.

摘要： Coinjection molding shooting pot cooling apparatus and method are configured to cool a shooting pot cylinder which, in combination with a shooting pot piston, injects a melt through a coinjection nozzle having at least two melt channels ending at the same gate. Preferably, a heat sink sleeve is disposed to contact an outer surface of a rear portion of the shooting pot cylinder. The heat sink sleeve is configured to remove sufficient heat from the shooting pot cylinder to increase the viscosity of the melt therein, thus reducing melt leakage between the shooting pot piston and the shooting pot cylinder.

摘要： An injection molding apparatus comprises a manifold having a manifold channel for receiving a melt stream of molten material under pressure and delivering the melt stream to a nozzle channel of a nozzle. A mold cavity receives the melt stream from the nozzle and the nozzle channel communicates with the mold cavity through a mold gate. A thermocouple is coupled to the mold core of the mold cavity in order to measure the temperature of the molten material in the mold cavity.
