With the mold in vacuum? Could work if you mix exactly the amount of resin to just fill the mold and can shut the valve at just the right time. The vacuum would pull the resin in and should fully fill the mold but you'd have to be careful so it wouldn't suck it all out the vents in the mold. Using the ~14.5 PSI surface pressure of the atmosphere to push the resin in, you shouldn't need very much vacuum. Too much pressure difference and it might simply blow the resin through the mold. Don't want resin in your vacuum pump! Experimenting with one of those cheap compressed air powered venturi types could be a good idea so you don't chance ruining a rotary vane pump. I'd try a couple of ways. Just vacuuming the resin in and vacuuming it in followed by applying pressure. ------------------------------------------------------------------------------ October Webinars: Code for Performance Free Intel webinars can help you accelerate application performance.
