Picture of How to vacuum form chocolate molds
I did this at TechShop Menlo Park. http://www.techshop.com

With a vacuum former you can form food grade plastic to make molds for chocolates and other food items. I documented the process.

Step 1: Turn on vacuum former

Big red switch in the back powers the vacuum former on. The Object to be molded gets placed on the screen and dragged down with big handle on the side. Plastic is loaded into the frame and latched on both sides. Turn on switches  to heat areas as big as plastic sheet.

Step 2: Vacuum form

When the plastic starts to sag pull large red handle toward you and push mould button. Then push release and retrieve the object.

Step 3: Melt chocolate

I made a double boiler out of a crock pot and melted chocolate chips

Step 4: Melt

My first melt batch ended up overcooling and rehardening into clumps. Then I added a little oil to the second batch and  got the desired consistency.

Step 5: Pour and decorate

I I added coconut flakes to the bottom while chocolate was still molten to make furry bottoms.

Yummy! :)

Looks awesome :)

What kind of plastics did you use? PS (polystryreen), pet or abs ?
And is it easy to get the chocolate out of the molds ?
