Traffic sign manufacturers, as an indispensable and important part of the road traffic infrastructure, whether it is highways, national highways, or township streets, always play a very important role. Large traffic signs such as 4.8 meters * 6 meters, small Such as small round cards and triangle cards. A very important part of the production process of these signs is the connection process between the aluminum plate and the chute. The old-fashioned connection process mainly includes two types:
One, electric welding-is to weld the aluminum plate and the chute
Disadvantages 1, pollute the environment
Disadvantages 2. You must have an electric welding certificate to operate, and electric welding is also harmful to the human body;
Disadvantages 3. The salary of welding professionals is also higher than that of ordinary workers
Disadvantages 4. Many expressways have clearly stipulated that welding is prohibited.
2. Drilling-rivets-then polishing (the process is to first drill the aluminum plate and the slide groove, then pass the rivet through the hole of the aluminum plate and the slide groove for riveting, and then polish the surface of the aluminum plate after the rivet is riveted, because Only by polishing and smoothing, can the reflective film be clean and smooth after pasting. If the rivets are protruding or recessed, there will be obvious bumps or bubble pits after pasting the film;
Disadvantages 1. There are many types of personnel required, and labor costs are high, such as aluminum plate punching personnel, chute rivet drivers, polishing personnel, etc.;
Disadvantage 2. It affects the environment and personnel health, because a lot of debris and dust will be generated during drilling and polishing, and the operator will breathe into the body, which will cause harm to the body;
Disadvantages 3. The product has a long production cycle. As a post-work of road traffic, signs usually have a relatively tight delivery time, and so many processes lead to a long production cycle and affect the delivery time.
