For that type of object is where I use a syringe, and the results I have had have been excellent, no bubbles, only burr (flash) that if you arrange the parting line well it is not noticeable and it is easy to clean, what I do is that in a two-part mold, I place the vents facing the mold, where they protrude in the solid part of the silicone and not in the part where it cuts and opens, when the pieces come out they look like the plastic pieces in the molds of injection of a factory

Hi Robert, Fun channel! Vacuum forming may be a good solution for the lamp shade project. 1/8 inch plexy or acrylic would work. Simple mold/form. Bead blast for frost finish... make 2 for matched set. ; ) Could also use your molds and a clear thickened resin. Fill mold and use inner to squash the resin. May have a thicker parting line but who cares! For the glass dome. Try making a glove mold outer mold with split shell. Then make a fairly stiff core glove mold. Pour the clear in the gap with a riser. Should make a part with no parting lines and better wall thickness consistency.

If you look closely you will see that I was vibrating the mold by hand as I poured it.

[@vernonleeper]

Interesting casting, even with that geometry, it seems like the more “pits” the more difficult it is to push the air out. High pressure injection molding you can force the air to fill the part. You have thought about it, because when you make the mold you vent it where you do. You ever make a mold and, cast a part , then think what if I moved this here and that there, try it and it works better? Adding more vents in the trouble area help on something like this, or does it just make it more difficult to clean up post casting? As always Robert, great video, learning more and more you are the master caster. Thanks for sharing.

[@RobertTolone]

The whole game is figuring out the FEWEST vents and sprues you need for a giving part. It's all about getting a clean casting with the least possible cleanup.

[@jasonsmith9662]

You have to degas the silicone with a vacuum chamber right before you poor it, you will get no more bubbles, the pressure pot really only works resin

[@michaelstephenson7264]

to eliminate those bubbles, you need to cast your rubber molds under pressure as well. the flaws are from your resin being pressurized into a weak point on the mold (likely a bubble trapped while curing.)

[@RobertTolone]

When a mold has a bubble in it, the casting has a bump where are the resin was forced into the mold. My casting flaws were voids, not bumps. And I never, ever pressurize rubber while it’s curing because you risk destroying the model if it has voids inside of it. This I learned the hard way early in my career.

Make a two part mold, core and cavity, part fill the cavity and then plunge the core into it from above. For this you need good indexing, tooth picks work well. If there are any bubbles, vent the core by cutting tiny vents into the core at the problem areas.

[@RobertTolone]

Thank for the suggestion Greg, I appreciate your input. I evaluate my methods by doing time/material studies. I’d love to see one on your method. Keep careful track how how long it takes you to make the two-part mold. Then time how long it takes to make each casting as well as how long it takes to clean the flash from those 100% parting lines and all those little tiny vents. Count up the bubbles too because I guarantee you’re still going to get some. Also measure how much resin waste you get with the plunge method. Let me know the results.

Would this work better if you designed the mold for injecting the resin? Like using a syringe... I'm just curious. I have a project where I am injecting urethane resin with a large syringe. The part is much larger, but it is thin, between 1-3mm thickness. (BTW, I like the pressure chambers. Simple and effective.
