<p><P>PROBLEM TO BE SOLVED: To provide non-stick fixtures 50, 60 for selectively covering a workpiece 10, and a method of working the same. <P>SOLUTION: The non-stick fixtures 50, 60 selectively cover portions of a workpiece 10 during application of a workpiece coating. These fixtures have predetermined surfaces thereon having an average surface roughness of about 25 Ra or less and a Rockwell hardness of about 65 Rc or more. The controlled average surface roughness ensures that these fixtures 50, 60 are non-stick with respect to the workpiece coating being applied to the workpieces disposed therein. The controlled Rockwell hardness ensures that the desired average surface roughness can be maintained throughout repeated use of the fixture. These fixtures 50, 60 reduce the workpiece coating bridging that occurs between the fixture and the workpiece 10, and also reduce the amount of overspray that occurs on the workpiece, thereby minimizing the amount of handwork and/or rework that is necessary after the workpiece is coated. This improves process cycle times and yields significantly. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
