Ren DT 082 fill for molds

General Composites Discussions Composites Talk

I have been looking into casting molds using Ren DT 082 high density filler and epoxy, the goal is to have a mold that can be fairly easily yet extremely strong. The current molds we are using are polyester tooling resin, tooling resin and infusion. The biggest issue we are running into is molds deteriorating fairly quick. The parts are epoxy, molds are polyester, and a high mold cycle is required.

Would we be better off producing epoxy molds using the standard method of infusion, or would a cast mold using DT 082 and epoxy be significantly better?

Here is a little thread I started , This is how most solid surface bench top material is made.
I just swapped acrylic or polyester resins , with a epoxy that I could control exotherm.
And the results are perfect :slight_smile:

Now all my production moulds are DT 082.
I’ve Pulled well over 100 parts out of my oldest mould and it’s perfect , just like the day I made it.
