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.  Always make sure the resin you are using is suited to the type of casting your doing.  Some resins cannot be used for deep casing in a single pour and will not perform well when used outside their use specifications.   Typical failures we have seen are chipping and cracking during demold. This is not a mold issue but a resin one.

What is the best way to demold a square / rectangular mold?

Allow your casting to fully cure. Once the casting is fully cured, remove only the end cap with the wing nuts.  Put the cap back on loosely then Flip over the mold and hit the mold on a hard surface several times. The casting should dislodge enough to be easily removed.  How-To Video: 

Do I need to use a mold release agent?

Mold release is not required on our standard premium-plastic molds. You can use it to make release even easier and it will not affect the mold.  However, you will 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.  These mold are designed to stand up to rigors of production type environments.

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. Especially with a new mold being used for the first time. You should also clean your mold after each use to remove any resin from the removable cap to prevent leaks.   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. 

Do you ship Internationally?

Yes, we have shipped to over 40 countries. Send an email to to place an international order.  Or check or Stockists tab at the top of the page to find local vendors who carry our products. 

Oops....I got resin on the threads.

Things happen, we get it.

Depending on your resin, you can soak the "frozen" stud and wing nut in Acetone for 24 hours to soften the resin, this should  allow you to separate the stud from the wingnut. Once apart, clean the threads well, then use two wing nuts back to back to create a jam nut and screw the stud back in.  Many customers report this works well for them.  If that does not work for you, Send an email to and we will try to assist. 

We also offer a replacement hardware / repair kit on the website.  There is usually no additional charge for shipping if you order it with another product.  Shipping for just the repair kit is $3.
