Step 2: Wax Tree Assembly

Picture
It is typically uneconomical to make small parts one at a time, so wax patterns are typically attached to a wax “sprue”.  The sprue serves two purposes
  1. Provides a mounting surface to assemble multiple patterns into a single mold, which will be later filled with alloy
  2. Provides a flow path for the molten alloy into the void created by the wax pattern(s)
The wax between the pattern(s) and the sprue are called “Gates”, because they throttle the direction and flow of the alloy into the void made by the pattern.
