Precision casting wax, also known as investment casting wax or lost wax casting wax, is a specialized type of wax used in the precision casting process. It is primarily used to create intricate and detailed patterns or molds, which are later used to produce metal castings with high precision and accuracy. The wax is first melted and then injected into a metal mold or pattern, which is usually made from aluminum or steel. The mold is designed to replicate the final shape and dimensions of the desired metal casting. Once the wax has solidified, it is removed from the mold and assembled with other wax patterns to create a complete wax tree or cluster. The wax tree is then coated with a ceramic shell, which is created by repeatedly dipping the tree into a ceramic slurry and then coating it with a fine ceramic powder. This process is repeated several times to build up a thick and strong shell around the wax patterns.
