Hi all! I use our FL 2 printer to create small injection molds for custom products to be injected with soft medical grade silicone. We typically use Biopor silicone. I have problems sometimes with getting all the resin(FL clear resin) cleaned out entirely from the mold. Currently I am using a syringe to individually rinse out each mold with IPA. I essentially force inject the IPA into each injection port and do so until I cant see resin coming out of the drain holes. They all then go through a fifteen minute sonic bath in IPA. Problem is that as thorough as I am, I still have post cured issues with the molds having (I’m guessing) uncured or not fully cleaned molds that will make the silicone come out slimy. I have used a product from Detax called cast separator which works but the whole process takes longer than I would like. Also when the silicone does come out slimy I have to reprint the molds, which is very inefficient. So the question is, any suggestions for more thorough cleaning of the injection molds? They are very small and have small nooks and crannies. I also asked if FL thinks their new cleaner will be able and efficient in cleaning inside small injection cast molds. They say it will but as of now will not offer a return policy if it doesn’t do the job it says it will. Does anyone else print small injection molds and have a similar problem? This is being used in a commercial application so efficiency is key.
Thanks ahead of time!
