In the past, all kinds of vertical and horizontal pipes and cables were marked by the inkjet marking and labeling. Once laid out, these pipes and cables are used for a long time and they have to face the surroundings. It has caused a lot of unnecessary inconvenience due to the frequent wear and tear since most of the pipes and cables are air exposed or buried underground.
The characteristic of laser markings is clear and permanent, with no wear and tear. It is also environmental friendly.
Thus, the pipes and cables are marked by laser marking machine now.
