"Make sure to melt the wax out completely at around 400 degrees then slowly bring it up to about 1000 - 1100 to completely bake the mold. "

INVESTMENT CASTING Machinable Wax can be used for Investment Casting applications only if it can be flash fired out of the molds at a temperature of 1800 degrees F. The reason the high temperature is required is because the wax expands so much when going from a solid to a liquid that it will crack the ceramic shell unless it goes into that high temperature so quickly that the material will just disintegrate before this change occurs.
