　　Metal flat plate signage is a type of metal signage that uses photosensitive signage to dissolve different colors into the adhesive film and present them on the metal plate through development, thus achieving a meaningful purpose. The following are the specific process and formulas for the metal flat sun signs that are commonly used in Beijing guide signs (the process of flat sun signs):

　　1) Blanking: It is required that the size of the raw material should generally be larger than the size of the plate making, and the board surface should be flat and smooth, without pits.

　　2) Pre treatment: ① polishing ② wire drawing ③ treatment ④ oxidation and other methods.

　　3) Water sealing: After removing oil and film from the treated board, it should be quickly immersed in water and should not come into contact with air.

　　Corroded metal tags Corroded metal tags are also known as etched tags. Mainly investigate convex or concave metal tags made by processing with mask and etching after processing. Manufacturing process of corrosive metal signs:

　　Blanking: According to the size requirements of the drawing (layout size), add a rough edge of no less than 5mm around. The 720 type pedal type cutting machine is used for cutting boards, and the surface is required to be flat with no burrs around.
