Silicone Mold Blank

March 18, 2014 in 8 Channel PDU by Joshua Oster-Morris

I am going to make a silicone mold as the polypropylene mold has been a pain to work with. Most of the parts have been ordered. This is the master I’ve drawn up. It is much taller than is necessary, but it does allow me to make the pour a lot less of an exercise in dexterity. I can pour in the correct volume and then left gravity settle it down to the right volume. I am going to do it upside down and a friend suggested. This allows me to put some heat sink features and a legend directly into the Motobrain which ought to be super cool at the end of the day. Not including the tabs, Motobrain is 3.5″x2.5″x1.5″. The tabs can be sawed off.
