PPR tube laser marking application, RFH 355nm UV laser is efficient and clear

With the development of laser technology, the application of laser technology is very common. Its high efficiency, non-contact, clean and environmentally friendly features are favored. The most common one is laser marking. In this article, we will talk about laser marking in PPR. tube application.

PPR, commonly known as three-type polypropylene, has the characteristics of high temperature resistance, corrosion resistance, high strength and long life due to the use of random copolymerization technology. It is widely used in building water supply and drainage, urban and rural water supply and drainage, urban gas, industrial fluid transportation and other buildings Municipal and industrial and agricultural fields.

Any product is inseparable from the factory marking, and the same is true for PPR tubes. Marking on PPR tubes mainly includes inkjet printing and laser marking. In terms of marking efficiency, marking effect and marking time, laser marking has very good advantages. The main manifestations are:

First, the mark after laser marking can be retained for a long time, will not fade or disappear, and has a certain anti-counterfeiting effect;

Second, the production efficiency of laser marking is high. It only needs to be integrated in the assembly line, and can be quickly marked on the tube with the vision system, computer program, etc., to meet the requirements of mass production;

The third is that laser marking is more flexible for the arc surfaces of some large-diameter PPR pipes, and it can also provide highly customized marking services according to the needs of upstream customers;

Fourth, no other consumables are required, which is environmentally friendly and cost-saving.

The industrial-grade nanosecond solid-state laser developed and designed by RFH, outputs 355nm ultraviolet laser, with excellent beam quality (M2<1.2), repetition frequency from single pulse to 500kHz, heat-affected zone is very small, and the accuracy of marking can reach micron level. The letters, numbers, trademarks, or complex graphics, one-dimensional codes, two-dimensional codes, etc. can be marked with ease, with high resolution, high speed, no carbonization, no deformation, and this laser has passed rigorous testing and inspection , The performance is reliable and stable, and it can adapt to 7*24h production operations in an industrial environment.

As a laser with a wide range of applicability in the marking industry, this 355nm UV laser can also be used for fine marking of PVC pipes, metal nameplates, artificial crystals, glass, etc.
