Laser marking machine has played an irreplaceable role in the plastics industry, marking clear and beautiful production date, logo, company name, parameters, indicating name, serial number and other information on plastic products. It directly improves the brand influence and user experience of the product. Today Leapion Laser introduces the application characteristics of laser marking machines in the plastics industry.

Generally speaking, laser marking machines are widely used for metal and non-metal marking. Laser marking of plastic products depends on the material of the product and what kind of process needs to be achieved. for example:

If the product material is plastic, you can use optical fiber marking machine, UV marking machine or carbon dioxide marking machine; if you just type on plastic products, and the requirements are not high, optical fiber is fine.

If the requirements are high, the UV is passed, or the logo that is required to be printed has no feel, then a UV laser marking machine is required.

Laser marking machine has the following two notable features in plastic marking:

1. High marking accuracy, which can realize fine marking

The laser of the laser marking machine adopts a diode-pumped laser, which has the characteristics of high efficiency. The laser marking machine also has good focusing ability, which is very suitable for fine marking. Diode-pumped solid-state lasers have high beam quality, enabling the laser to obtain a small focal diameter during marking. In this way, track width markings accurate to the micrometer can be achieved on tiny components.

2. Absorption characteristics: absorb excess heat

Lasers used for marking plastics typically generate radiation in the infrared wavelength range. Green and UV lasers target plastic and semiconductor materials.

In the special marking application of laser marking machines, the use of UV wavelengths creates new possibilities for laser marking of plastics. Without heating, the short wave directly photochemically reacts with the plastic compound without causing damage to the material.

In addition to the above two salient features, laser marking plastics has the following advantages:

1. Safety and environmental protection

Laser marking has the performance advantages of non-contact processing, zero cost of consumables, zero risk of pollution, high operation accuracy, long maintenance-free time, and low failure. It solves the problems of high pollution, high consumables, high failure, high maintenance, high imitation, and high restriction in ink coding equipment. It can be used in the food industry, mobile phone manufacturing, medicine and other industries, and will not be affected. limit.

2. Fast marking speed, good marking effect and strong anti-counterfeiting ability

The marking speed is fast, the operation method is simple and convenient, the marking effect is exquisite and permanent, which solves the problem for manufacturers who want to mark clear and beautiful production date, logo, patent number, company name, parameters, indication name, serial number, etc. on plastic products. The demand for information can improve the brand effect for manufacturers, promote brand promotion and user experience.
