Holes in resin mold

[jigman]

I poured a resin mold using a nearly flawless ribbed worm.When I pulled the worm out of the mold there were holes or gaps in the ribs.Are these caused from air bubbles in the resin?If so how do I solve this problem?

I use clear polyester casting resin so you can clearly see the bait on the bottom after the resin is poured into the mold . After pouring in inspect the bait and look for trapped air bubbles. I like to use a fine paint brush to lightly brush the bubble(s) off the bait and up towards the surface . usually once you get the bubble going it will float up to the surface but if not help it along with the brush . I have made a few zipper molds that came out perfect using this method..............hope this helps

I do the same thing, only I tease the bubbles loose with a toothpick.

I do my molds in a metal, square cake pan. Super glue to the bottom well. To start to release the bubbles, if there are some, I tap the pan with a kitchen knife. This will start the bubbles toward the surface.

If you pour the resin into the mold very slowly you should reduce the amount of bubbles.

Oh, I forgot, do not stir the resin after you add the activator like you are trying to make whipped cream. Do it slowly.

Hope this helps.
