The official statement is: the common metal sign production mainly includes metal flat sign, metal silk screen sign, metal corrosion sign, metal electroplating and metal electroforming nameplate, metal heat transfer sign and metal sandblasting sign. Then let’s talk about the first metal sign production process: metal flat sign.
The way of metal flat signage is mainly to use photosensitive signage. Dissolving different colors into the film, so that it is displayed on the metal plate by the method of development, so as to achieve a meaningful purpose of a metal sign.
The following are some of the process processes of flat-screened signs that we often come into contact with:
1. Blanking: It is required that the size of the wool is generally larger than the size of the plate (more than 5mm), and the surface of the board is smooth and free of pits.
2. Pre-treatment: ① polishing ② wire drawing ③ treatment ④ oxidation and other methods.
3. Water sealing: After degreasing and removing the film, the treated board is quickly immersed in water and cannot be in contact with air.
4. Glue: the configuration of glue. Glue: 200-230g Water: 1000ml, boil in boiling water for 2 hours to fully dissolve the glue, add 25-30g of photosensitizer (ammonium butyrate) when the temperature drops to 30-50°C, and spread the glue evenly on On a metal plate, dry and ready to use.
5. Printing: SB750 type vacuum printing machine can be used for photosensitive printing. After the lamp is 60-90cm and the time is 40-80 seconds, it is placed in warm water for 1 minute and then placed in the color solution for dyeing.
6. Gloss preservation: After fully dyed brand, after drying, apply gloss retention paint with brush or spray gun (usually use eye brand baking paint or no-bake gloss retention paint).
Flat signs are generally used on indoor supplies, small household appliances and equipment not affected by severe weather. The advantage is that the plate making process is simple, the speed is fast, the delivery is timely, and the rate of defective products is low. The disadvantage is that it is easy to fade after being exposed to the sun and rain. Can not do outdoor signs.
One of the production processes of metal signs, metal flat signage, you should already know it now!
