Process: Teddy Bear Molds

Teddy Bear Blanket Mold Production Process

So the basic concept for this project was to create a mold so we could cast a few teddy bears as one part of a fundraising project. This is the first bear chosen for the project and a step by step of his mold creation. The images below show the process of creating the blanket mold with the rubber insert. The next bear will have much more texture so we will use a slight variation on the technique by using a more flexible rubber.

The final pic shows the first castings and some issues with the cooling of the wax. We have worked out the kinks and the next ones should work fine when we brush on the first layer of wax instead of a slurry or slush casting technique.

The whole process took about two days since it takes about 8ish hours for each section of rubber to cure.
