Dissolvable core material for injection molding?

General Composites Discussions Products Talk
#1

Hi everyone, we want to injection mold an anatomical model with complex hollow interiors using a custom polymer.

Because of this, we are looking into using a soluble mold. The issue is that the polymer itself has a high water content (over 70%). The injection molding takes place at 90 degrees Celcius and then it goes through several freezing and thawing processes.

We have tried working with Aquacore and Aquapour from Advanced Ceramic Research, but it obviously broke down.

Does anyone have suggestions?

Thanks.

could try using wax that you can machine or cast in another mould, then melt out after. Or a foam that can be removed by solvent after.

XPS foam?

some random text as the above text was to short to pass through the forum filters. :slight_smile:

Wax will be a better option for molding. I would suggest you to go with it.
