Casting cast in resin small hands...

I put vent holes in every finger when I do hands and I've done some TINY hands)

usually put a wider pour hole around the wrist. Yes, it requires more clean-up but if I pour nice and slow I tend to get less air trapped there.

 

You may try an indirect pour? This may require that you make a new silicon mold for the hands? However, that may be more affordable than a pressure pot at this time?



The above diagram is NOT TO SCALE. Make your sprues and vents the best size for the hands you are casting.

 

Are the fingertips pointed down in your mold and not filling? What I do is (and a pressurepot won't fix this) pour the resin, then cover any holes, and tap the mold hard on the table a few times to shake the resin into the tips. Then top up as needed with more resin. This is where it is handy to use clear silicone so you can see if the fingertips are filled or not.

 

injection casting

Try injecting the resin with a catheter tip syringe

You can also use them to lay in resin onto both halves of the mold then assemble the mold and pour/inject the remaining resin. You'll have a lot of flash to clean up but you'll get your casts.

 

I'm so happy to hear that you found a solution to your casting problem, gerakina. I'm looking forward to seeing the photos of the bubble-free hands.

 

Mee tooo gerakina! photos pls!

 

I'd love to see those pictures too!

 

Yes, please - especially if there's pics of the casting process - I'm not sure I quite understand what the fix was, but it sounds interesting, and I'm excited to know of methods that might allow this stuff to be done without a pressure pot.
