Technical Field

[0001] The utility model relates to the technical field of investment casting, in particular to an investment casting shell cleaning device. Background Art

[0002] Investment casting, also known as lost wax casting, includes many processes such as wax pressing, wax repairing, tree assembly, slurry dipping, wax melting, pouring molten metal and post-processing.
