From my experience, 100% regrind use creates defective product. I think the maximum limit figure is somewhere around 15% regrind mixed in with virgin resin during injection molding. This figure does vary with different resins...

Soft tool aluminum molds are good for 100K shots and cost anywhere from $3000 and up (very high up). Check www.protomold.com if you don't believe me.
Hard tool steel molds are good for 1 million + shots and generally cost double what the soft tool molds cost.

So, seems like the minimum number of grilles that could be produced if a soft tool mold exists is 100,000 grilles.

Is BEA actually molding these parts? I see them on Goodmark's sight without the marker lights and paint... Just curious...
