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.
Claims20
A method of cold-forming a nozzle for a laser comprising:
- placing a slug of oxygen-free copper into a die;
- forcing a shaped mandrel into said slug causing said slug to be extruded around said mandrel;
- applying compressive force from said die onto said slug to define an outer dimension of the nozzle;
- and
- applying radial compressive force onto an inner surface of said slug to define an inner dimension of the nozzle.

A method of forming a nozzle for a laser comprising:
- placing a tube of metallic material into a die;
- directing a shaped mandrel into said slug causing said slug to be extruded around said mandrel;
- and
- applying an outward radial compressive force from said shaped mandrel onto said tube thereby defining an inner dimension of the nozzle.
