High Flow Injection Molded Isolator

The requirements for this isolator were that it be flexible enough to conform to the edge of the part to isolate the chrome license-plate appliqué from the vehicle's sheet-metal body to prevent galvanic corrosion; that it be soft enough not to scratch the paint underneath; that it be sufficiently stiff to hold electrical components and permit snap-fit features in the appliqué assembly; that it be able to be processed on standard injection-molding equipment without excess flash; that it provide sufficient flow to fill a long (1,100 mm/43.3 in.) part at wall sections of 1.0-1.5 mm/0.04-0.06 in.); and that it be UV stable and colorable.  The new TPO material met all these goals while allowing injection pressures to be reduced, shortening cycle times 15% and reducing scrap 3%, while increasing the quality of the appliqué by reducing scratch and mar.  It was a drop-in to existing tooling, matching the shrink properties of the prior material, which was being phased out due to a raw-material discontinuation issue.
