An injection molding nozzle for dispensing of molten material includes an elongated body member having an outer surface, a first portion at a proximal end, a second portion at a distal end, and a central passageway extending longitudinally therethrough from the first portion to the second portion. The central passageway includes an inlet defined at the proximal end and splits outwardly at the second portion to form a radially extending passageway leading to an outlet. A tip member is coupled to the outlet to facilitate dispensing of molten material into a mold cavity. A groove is defined on the outer surface of the body member that winds from the first portion to a heated section of the second portion that is positioned adjacent to the tip member.
