Strange, I don't recieve my own posts in the forum. I have to wait for someone to reply.

Thanks to all for the suggestions. Phil, we have used that method in the past. The only problem we had was air bubbles (voids) in the potting. Of course we don't know this till you disassemble the mold.

Thanks again to all,

Karl

 Karl,

Another approach is using some of the silicone mold compound.  Make a connector the way you want it and then create a mold from this good part using one of the many silicone molding products.  If you are curing at room temperature you should get many good connectors from this mold.  If you are curing at 160° F you may find the maximum pulled form the mold is ten pieces.  I've used this process for many low run items.

Hi Steven and Steve. Thanks for posting the pics Steve. We just using Eccobond 45 cured at 160F. A clam shell mold would be good, but we are limited in our ability to machine parts. In the past, we have layered FR4 to get molds in the Z axis. We only have NC drill/router that does X and Y axis. Mabe I can dremel out a piece of Delrin or Teflon.
