Method of using image data in the production of thin wall extrusions

摘要

A method of coating metal wire with extrudate using an extrusion system. The method includes the steps of advancing the metal wire through an extrusion die of the extrusion system and extruding molten extrudate over the metal wire as the metal wire is advanced through the extrusion die. Image data is generated, using one or several electronic cameras, concurrently with the advancing, and extruding to provide visual feedback indicative of the concentricity or non-concentricity of extrudate surrounding the metal wire as the metal wire exits the extrusion die.
