ABSTRACT:
A method for cold-forming a nozzle for a laser includes placing a slug or tube of oxygen-free copper into a die. A mandrel is forced into the copper slug or tube. The resultant compressive force causes the copper to cold flow around the mandrel and the die to define an inner shape and an outer dimension of the part.
