I. Painting: 1. Painting marks: The paint film formed by painting is relatively uniform and has a good appearance, which can be mastered by workers after a period of practice. Logo signs can be directly sprayed with wax paper or templates, which is a way to identify sign production. For parts with complex shapes and precise pictures and texts, parts that cannot use waxed paper cannot be used. This is because the missing word board must be close to the component, otherwise the characters that pop up have virtual edges. Some logo designers rent this transition zone with imaginary edges to express patterns, which is another matter. 2. Spray guns are generally used for painting. There are two kinds of spray guns: those with air compressor and those without air compressor. 3. paint fog.
Second, painting: brush for painting, roller for large-area painting, pen, sharp stick and needle tube for painting or filling. They can directly identify sign production pictures and texts with paints or coatings, which is suitable for single piece or small batch production. House numbers, signs, advertising light boxes, and many large signs made by signs are painted. Small brush, sharp stick, needle tube, etc. Used for spraying or filling small sign sign production or small sign board.
Third, dipping: there are ordinary dipping and vacuum dipping, which are mostly used for rough surfaces such as castings, silicon steel sheets, coils and parts with holes and gaps. Using dipping paint to mark sign production is to partially protect the surface of parts, dip paint, paint, and remove the protective layer after drying to get the pattern used to mark sign production.
Fourth, pour paint: pour paint or coating on the surface of parts, and use gravity leveling or centrifugal leveling. The method of obtaining the graphics and text of the identification mark is the same as that of dipping paint.
Fifthly, centrifugal painting: The sign production method is similar to painting, except that compressed air is not needed.
