Abstract

A manufacturing method of a tool surface mark includes a first cleaning step, a first electroplating step, a second cleaning step, a drying step, a printing step, a cation removal step, and a second electroplating step. In the first electroplating step, the surface of the tool is electroplated, and a first protective layer is formed on the surface of the tool. In the cation removal step, the tool is placed into an electrolyte and then electrically connected to an anode, the anode is electrically energized, and metal cations on the surface of the tool and on the printing pattern are dissolved. In the second electroplating step, the surface of the tool is electroplate at potions without the printing pattern to form a second protective layer. The yield of the printing pattern increases and the printing pattern does not easy peel off.
