Nozzle with removable nozzle tip configured for improved heating

An injection molding machine comprising:

• a nozzle for transferring melt to a mold cavity, the nozzle comprising:
• a nozzle housing defining an exterior surface, the nozzle housing including threading along the exterior surface;
• a nozzle tip defining an interior surface, the nozzle tip including threading along the interior surface that matingly engages the threading on the nozzle housing such that at least a portion of an exterior wall of the nozzle housing and at least a portion of an exterior wall of the nozzle tip aligns to form a single cylinder comprising a continuous cylindrical surface when the nozzle tip is threadably attached to the nozzle housing, wherein the nozzle tip does not include a torque means to facilitate assembly and removal of the nozzle tip;
• a tubular heater enclosing exterior walls of nozzle tip and nozzle housing portions of the cylinder, wherein the nozzle tip does not include a torque means in any location that is downstream of the tubular heater and upstream of a mold gate of the nozzle;
• and
• an engagement tool for attaching or detaching the nozzle tip to the nozzle housing, the engagement tool comprising:
• a clutch for engaging the cylindrical surface;
• and
• a torque feature attached to the clutch.
