How to maintain and repair the luminous characters built by the marking machine

Nowadays, luminous fonts made by marking machines are becoming increasingly popular, and some large shopping malls, supermarkets, and squares also use large luminous fonts. Improper maintenance of these large luminous characters may result in significant losses. Let's take a brief look at how to maintain and repair the luminous characters produced by the marking machine. I believe it will be helpful for advertisers.

How to maintain and repair the luminous characters produced by the marking machine

For minor scratches on the surface that may not be significant, sandpaper is usually used for wet polishing. During polishing, the sandpaper should move in a circular motion, and the fineness of the copper sandpaper should gradually increase to over 600 mesh. Finally, toothpaste can be used for polishing. If it is a large-scale scratch or perhaps during transportation, or due to improper operation during construction, resulting in damage to the characters, it is usually necessary to remake the front of the characters. Usually, small scratches that we cannot see without careful observation do not require special treatment.

The luminous character device produced by the marking machine has a certain height, usually 3 meters above the door, perhaps on the second floor or other rooftops. Minor scratches do not require correction. Due to the detailed requirements and mastery of force and viewpoint in the operation of sandpaper used in the correction, it is necessary to avoid damage to other parts.

The protection notice for luminous characters made by marking machines: The resistor in the module plays a current limiting role and generates heat easily. Long term continuous use, once the resistor burns out, this module will not light up, and the light usually does not break. In order to reduce complexity and save expenses, it is recommended to use a module with two resistors. Purchase qualified single light bulbs produced by standardized manufacturers, and manufacture individual modules. If you need to purchase a module, you should check how many resistors are installed on the module, and it is better not to use a module with one resistor installed. Did anti-static equipment be used when manufacturing the module? If there is no additional anti-static equipment, even if the resistor is not burned out during use, the lamp is easily damaged by breakdown.

The above is the complete content on how to maintain and repair the luminous characters produced by the marking machine. I hope this article can be helpful to everyone.
