In order to distinguish the product brand, product type and meter, there will be various signs on the cable in the cable industry. Now most cable manufacturers use ink inkjet printer for inkjet printing. Ink jet printing, pollution, high cost and huge ink consumption. It is understood that the cost of ink purchased by a medium-sized enterprise in a year should reach 400000-500000 or even millions. Moreover, with the improvement of industry requirements, ink-jet coding can not meet the industry requirements.
Nowadays, laser marking machine has entered the cable industry. With its outstanding advantages, laser can meet the clear and lasting requirements of the industry demand, and the online cable industry is widely popular. Laser inkjet printer is used in the cable industry, which means that once the date, batch number, brand, serial number, QR code and other marks of cable products are sprayed, they can no longer be changed, which plays a great anti-counterfeiting role; It means that some fake and shoddy products can be resisted to prevent illegal manufacturers from taking advantage of them; It means that it can resist the chaos of the wire and cable industry, so as to improve the quality of wire and cable products. The initial investment cost of laser inkjet equipment will be a little higher, but it has no consumables and low power consumption. In the long run, it has many absolute benefits.
At present, the lasers used for cable code spraying are mainly divided into carbon dioxide laser marking machine, optical fiber laser marking machine and ultraviolet laser marking machine.
Carbon dioxide laser marking machine and optical fiber laser marking machine change color by burning the cable surface, which will damage the cable surface and have smoke.
The UV laser marking machine has a short wavelength of 355nm, which belongs to cold laser. It mainly forms discoloration by breaking the plastic molecular bond on the surface of the cable, without damaging the surface of the cable. And adapt to a variety of materials. In the future, more and more cables will use UV laser marking machine to spray code.

Laser marking is to use a laser beam to make permanent marks on the surface of various substances.
UV laser belongs to "cold processing", which can break the chemical bond in the material (especially organic material) or the surrounding medium, so as to destroy the material in a non thermal process, so as to realize the discoloration reaction. This cold machining has special significance in laser marking processing, because it is not thermal ablation, but cold stripping that does not produce "thermal damage" side effects and breaks chemical bonds, so it does not produce heating or thermal deformation on the inner layer and nearby areas of the machined surface.
At present, UV has a good application in non transparent plastic products, flexible film packaging, cable pipes and other industries because of its good absorption and low thermal damage.
