1. A casting nozzle for dispensing liquids in a casting operation, comprising:
a monolithic nozzle body being comprised of a cured photopolymer,
wherein said monolithic nozzle body includes interior surfaces and exterior surfaces, andwherein said interior surfaces adapted to receive a liquid and pass the liquid therethrough; and a conductive metal coating said exterior surfaces for providing a thickness in a range of about 2 ten thousandths-about 4 ten-thousandths of an inch,
wherein the monolithic nozzle body includes a plurality of dispensing channels and an inlet region coupled to the plurality of dispensing channels where the inlet region includes a first diameter and each of the plurality of dispensing channels includes a second diameter, respectively,wherein the first diameter is greater than each said second diameter,wherein the plurality of dispensing channels are symmetric about a centerline to form an inverted V-shaped bottom portion of the monolithic nozzle body,wherein the plurality of dispensing channels contact each other at a flow-dividing point at the centerline,wherein each of the plurality of dispensing channels comprises a bottom outlet portion, where each said bottom outlet portion is in a same horizontal plane as another said bottom outlet portion,wherein said each of the plurality of dispensing channels comprises a length portion situated between the bottom outlet portion and the flow-dividing point where said length portion is a straight shaped length portion, andwherein said second diameter includes a constant cross sectional area throughout a length of said each of the plurality of dispensing channels. |
