In addition to the metal plate, the required materials include etching tools (which can be etched by machine or by hand), etching solution, mask (ink or post-it notes, depending on the size of words in the process of making the mask), and paint (all kinds of paint and spray painting equipment, of course, the spray painting method can also be purely manual, which is also very efficient for ordinary titanium gold medals. If the text is relatively large, such as the 46 titanium gold medal awarded by the superior unit, the production process is relatively simple and the production process is not complicated.
