How to mold plastic
Prepare the master part.
The master part is the item that you will use to create the mold.
To prepare the master part, first wipe down or wash the item.
Once clean and dry, apply a release agent to the original item-this will ensure that the master part will pop free from the mold. Coat the item with a layer of bubble buster-this product prevents the formation of air bubbles around the master part.
