Signs are very common things, which can be seen in the streets. Most modern manufacturing processes are aluminum. Aluminum materials are welded, bent, washed, lathe, water cutting, wire cutting, grinding, polishing, wire drawing, electroplating, oxidation, corrosion and paint baking. The following is the manufacturing process requirements of identification signs.
How to make outdoor aluminum signs
1、 Requirements for aluminum alloy profiles:
- 1. Aluminum alloy profile and common plastic material accessories shall meet the quality requirements of aluminum alloy label profile.
- 2. The angle bottom fault of aluminum alloy profile shall be less than 1 degree.
- 3. Plane vacancy < = 0.4% * B (B is the width of profile).
2、 Paint baking process requirements:
- 1. A series of surface treatments such as cleaning surface residues, ash supplement and grinding.
- 2. Select environment-friendly high-quality paint for baking treatment. The paint baking room must be a dust-free particle workshop. The surface coating of the paint baking room shall be coated and baked for three times, and the coating thickness shall be greater than or equal to 35 microns.
- 3. The paint color shall meet the requirements of the planning scheme.
- 4. The finish film shall be smooth and uniform, and defects affecting the decoration effect such as flow marks, wrinkles, orange peel, bubbles and blending are not allowed.
3、 Silk screen printing process requirements:
- 1. Make screen printing and screen printing. Clean the surface with alcohol or white oil.
- 2. The color of silk screen printing shall meet the requirements of the planning scheme, and the font and image strokes shall be clear without deformation, sawtooth and other defects.
- 3. There is no ficant penetration between the color of silk screen graphics and the background color.
4、 As built appearance requirements:
- 1. After the completion of the equipment, the appearance of the signboard shall be exquisite, without screws, scratches, bubbles and ficant uneven color. The baking paint must have no ficant color difference, and the materials used shall meet the requirements of the planning scheme.
- 2. Label equipment is easy to replace and maintain.
- 5、 All graphics of the identification system shall comply with the latest rules and requirements of "gb10001 graphic symbols for public information signs";
- 6、 The Chinese and English characters of the identification system shall conform to the rules of the relevant national and buying units. If there is no such standard, the translation shall be recognized by the planning unit and the buying unit; The Chinese and English characters, colors, etc. of all signs and signs shall be submitted in writing to the buying unit for admission before manufacturing;
- 7、 Various metal profiles and components of the identification system body, together with the internal section steel framework, shall meet the relevant national planning requirements (shall meet the requirements of wind load resistance) and ensure the strength; The closing shall be waterproof
- 8、 The identification system is necessary to ensure that the equipment is healthy and easy to disassemble. All equipment pendants and bolts of the sign system shall be galvanized for anti-corrosion treatment. All equipment of the identification system shall be closely coordinated with other equipment without danger;
- 9、 The part of the profile selected for the identification system shall be blocked without burrs, metal chips and other pollutants;
- 10、 The appearance of the products of the identification system, whether the original appearance or with other coating layers, shall be free of scratches and damage;
- 11、 All identification systems shall consider the convenience of equipment and maintenance; After the signs are manufactured, they shall be inspected. The sign manufacturing mall is disordered and the quality is mixed. The inspection requirements are: "two touch and one look". The sign inspection specification: check whether there are scratches on the surface of the aluminum sign, and whether the color of the sign is the same as that of the sign.
Touch: touch whether the surface of the aluminum word sign is smooth and has concave convex changes; Touch whether the stroke and the rising part of the stroke are flat, leaving defects made by welding and other processes.
