Intro: Fast Hot Glue Mold for Small Things


Here I will show to you how to make a fast, simple and cheap hot glue mold to reproduce small things.


Step 1: Materials


You will need:

1. Some oil

2. Hot glue gun


Step 2: Preparing the Thing


The small thing that you want to make a mold must support a temperature about 100 degree Celsius, that is the hot glue temperature.

I choose a half-dollar coin, but you could choose anything else.

First put the object above a smooth surface. Then spray a little oil on it and spread it evenly with a piece of cotton. Spread a bit around too.


Step 3: Making the Mold


Wait for the hot glue heats well and slowly apply it above and around the object. Use your hand to push the glue rod inside the gun, to help the flux exit evenly. Try to avoid make bubbles (sometimes is difficult).


Step 4: Separating the Object


Wait until the glue cools well and carefully peel the mold out of the object.

Now you have a fine plastic mold with all the details of the object.


Step 5: Reproducing the Object


Spread a little oil inside the mold.

Now fill the mold with the material of your choice. I choose epoxy, but you could use another material, like clay or acrylic resin.



Step 6: Finalizing


Wait for the material to harden and carefully retires it.

Make the finishing, cut the scraps and paint it, if you want.

Have fun!

    that epoxy could have made a more durable mold.
    hot glue is cheaper though

    would i be able to reverse it? like use clay and use that as the cast, then put hot glue into that cast?

    I think that it's possible. The clay must be a little more dry, maybe. Try it! Don't forget to tell me the result. :)

    it worked OK. the mold was hard to get out so i left a little bit hanging out and then cut it off. the clay crumbled after about 5 uses, but it was worth it!

    Yes, you can make both sides, but you have to make align marks and good oil lubrication between them.

    I wonder if you could use this method for doing stamps? Just gluing the hot glue mold onto a piece of wood or cork... hmm, something to try...

    Maybe you have to make a two halves mold. It depends of the details of the object.
