Kecmark outlines when to use CO2 or fiber laser marking

Hangzhou Kechuang Mark Technology Co.,Ltd has detailed how manufacturers can choose between CO2 and fiber laser marking based on material, production line needs and traceability goals. The company says the right wavelength can improve mark quality, cut consumables and support faster, more durable coding across packaging, metal parts and other industrial substrates.

Why it matters: - Manufacturers are under pressure to improve precision, speed and traceability while reducing waste and downtime. - Choosing the wrong laser type can weaken mark quality, raise operating costs and limit readability across the product lifecycle. - The decision affects packaging, electronics, automotive, aerospace, food and pharmaceutical production lines.

What happened: - Hangzhou Kechuang Mark Technology Co.,Ltd published a breakdown of CO2 laser versus fiber laser marking for industrial use. - The company positioned its 300 series CO2 systems for non-metallic substrates and its 700 series fiber systems for metals and hard plastics. - The company provided more information on industrial marking and coding solutions through its website.

The details: - CO2 laser marking systems in the 300 series operate at 9.3 to 10.6 micrometers. - That wavelength works best on paper, wood, certain plastics, PET bottles, cardboard packaging and flexible films. - CO2 marking creates a localized thermal change without damaging the product structure. - CO2 systems can also create a frosted effect on glass or ceramics. - Fiber laser marking systems in the 700 series use a 1064 nm wavelength. - Fiber lasers are built for stainless steel, aluminum, alloys and dark, high-density plastics. - Fiber marking supports deep engraving, annealing and surface stripping on hard materials. - Fiber systems are suited to serial numbers, barcodes and logos that must remain permanent under heat, oil and abrasion. - The company said its 300 series includes 9.3, 10.2 and 10.6 micrometer wavelength options for specific polymers. - A 9.3 micrometer wavelength is designed to reduce the pinhole effect on PET. - The systems support 0 to 360 degree installation angles. - The hardware carries IP54 protection ratings for dusty or humid environments. - The 700 series fiber laser sources offer a lifespan of up to 100,000 hours. - Hangzhou Kechuang Mark Technology Co.,Ltd says it holds more than 40 patents and software copyrights.

Between the lines: - The company is framing laser selection as a materials-science decision, not a one-size-fits-all hardware purchase. - CO2 systems are being positioned around clean, consumable-free coding for packaging lines where hygiene matters. - Fiber lasers are being positioned around durable identification for high-volume industrial environments where automated vision systems need high-contrast marks. - The sustainability argument is tied to lower consumable use, less waste and fewer maintenance tasks than inkjet systems. - The economic case for fiber is centered on low operating costs after installation, plus energy efficiency and remote monitoring. - The broader pitch is that software-linked marking equipment can help reduce batch-coding errors and downtime.

What's next: - Manufacturers evaluating marking systems will continue to match wavelength, substrate and production environment before selecting equipment. - Hangzhou Kechuang Mark Technology Co.,Ltd is likely to keep emphasizing traceability standards as industrial coding becomes more automated. - The company says its membership in the China Machine Vision Industry Alliance and the Zhejiang Food Industry Association supports that positioning.

The bottom line: - CO2 lasers fit soft, non-metal materials. - Fiber lasers fit metals and other hard, high-durability applications. - In industrial marking, material compatibility determines performance more than a universal machine choice.
