Step 4. Lost wax Casting reproduction using wax injection. 21083

This is the fourth step in the reproduction process I use for making my jewelry. Here I have mixed up the mold compound and pour it in over the sprue trees. After the video stops, the molds are degassed in my Vacuum machine. I allow them to "boil" for 30 seconds usually before releasing the Vacuum. This insures there are no bubbles on the mold and that the fine details are transferred.

You don't use no-bubble, or vacuum?

@bearhedded I use both "vaccu-coat" to protect from bubbles and I degas it in my vacuum chamber. I guess I hadn't realized I left out the part about the Vaccu-coat. If you read the description it mentions the degassing process though. Thanks for the heads up on that!

Can you use plaster?

[hellotoy21]

I don't think that would be a good idea. Depending on the specific type of plaster used, you could have a violent reaction. Investment mix is relatively inexpensive. If you info for where to purchase it, just let me know.

What is the mold compound made of or where can it be purchased? Would the compound work fine for casting aluminum? Looks like compound dissolves easily in the water?

thanks
