There are many types of lasers. According to different application scenarios and processing needs, select the appropriate wavelength and power to demonstrate laser processing performance. At present, fiber laser marking machines, UV laser marking machines, CO2 laser marking machines and green laser marking machines are commonly used in the industrial laser field.
The application of laser marking plastics has become popular, but the marking effect will be affected by the laser source and the composition, color, and additives of the plastic. As a synthetic polymer material, plastic has plasticity and cost-effectiveness. It is widely used in electronics, automobiles, medical, packaging, construction and consumer goods industries, such as electronic product casings, insulating workpieces, vehicle body parts, pipes, food packaging, infusion bags, medical tubes, toys, etc. Common laser marking plastics include polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyethylene terephthalate (PET), polycarbonate (PC) and other thermosetting materials.
When choosing laser processing equipment, you may be stuck in the dilemma of which machine to choose. Therefore, we used a fiber laser marking machine and a UV laser marking machine to mark several plastics with different compositions. The contrasting effect can be seen in the video.
Fiber laser marking machines are widely used in many industries and can make deep, high-contrast marks on plastic surfaces; UV laser marking machines process plastics with high beam quality, fine processing quality, and high absorption rates. In addition, UV laser marking is a cold processing method that can reduce damage to materials and impact on workpiece performance. It has obvious advantages in processing heat-sensitive plastics and is favored by many medical and electronic product manufacturers.
The choice of fiber laser or UV laser depends on the requirements of the specific application, such as the characteristics of the material, the marking effect and the need for cost control. We recommend that you mail us samples and our engineers will process and test the samples to determine which laser marking system can meet your needs.
