FAQ (Frequently asked Questions)
Which Resins/Epoxies can I use with these molds?
We are big fans of Alumilite Clear Slow, but any epoxy or resin will work. Keep in mind that some have a low viscosity and may take days to fully cure before demold.
What is the best way to demold a square mold?
Allow your casting to fully cure. Once the casting is fully cured, remove only the end cap with the wing nuts. Flip over the mold and hit the mold on a hard surface several times. The casting should dislodge enough to be easily removed.
Do I need to use a mold release agent?
Mold release is not required on our square UHMW type molds. However you willl need to apply a liberal amount of release agent (such as Stoner Urethane Mold Release) for any Clear PVC type molds.
What are your molds made of?
We only use the highest grade of plastics available.
What happens if I have an issue with a mold?
Check to make sure that you have adequately tightened all of the wing nuts on your mold before casting. Feel free to send an email to if you have any questions or concerns about your mold.
What is the time frame for a custom order?
Please allow up to 2 weeks for any custom molds before they ship.
How much resin should I mix up for each mold?
The easiest way to figure out how much resin you will need is to use this simple calculator. Multiply your Height x Weight x Length x .55. This will give you the required amount of epoxy resin in oz.
