Kecmark outlines how to choose a laser marker for plastic

Hangzhou Kechuang Mark Technology Co.,Ltd says matching laser wavelength to plastic type is critical for readable codes, less heat damage and better production-line performance. The company detailed CO2, fiber and UV options for packaging, engineering plastics and medical-grade materials in Hangzhou, China, on June 23, 2026.

Why it matters: - Plastic marking failures can slow production, damage thin parts and weaken traceability. - The wrong laser wavelength can cause fading, melting or poor contrast on finished products. - Manufacturers need the marking system to match the polymer, not just the power level.

What happened: - Hangzhou Kechuang Mark Technology Co.,Ltd, known as Kecmark, published guidance on selecting laser marking machines for industrial plastic applications. - The company framed wavelength compatibility as the core decision for transparent polymers, dark engineering plastics and sensitive medical materials. - Kecmark included product-line guidance for its 300 series CO2 lasers, 700 series fiber lasers and 900 series UV lasers. - More information is available on the company's announcement.

The details: - CO2 lasers in Kecmark’s 300 series operate at 10.6 micrometers and are designed for non-metallic materials and organic polymers. - The 300 series is positioned for PET beverage bottles, PE/PP packaging films and paper-based composites. - Kecmark says the 300 series supports high-speed online coding and can replace inkjet systems to reduce consumables and maintenance. - The same thermal effect that helps on packaging can also melt extremely thin or heat-sensitive films. - Fiber lasers in Kecmark’s 700 series use a 1064 nanometer wavelength for dark engineering plastics such as ABS, PC and Nylon. - The 700 series creates a permanent mark through controlled carbonization and is aimed at automotive and electronics uses. - The 700 series carries an IP54 protection rating for dusty or humid factory environments. - UV lasers in Kecmark’s 900 series operate at 355 nanometers and use cold marking technology. - The 900 series breaks molecular bonds through a photochemical reaction and produces minimal heat. - Kecmark says the 900 series is suited to thin-walled PET, medical-grade catheters and flexible PCBs. - The 900 series also comes in a 70mm short-focus configuration for tighter installation spaces. - Kecmark says transparent materials such as mineral water bottles need high infrared absorption to produce clear marks at production speed. - Dark rigid shells for electronics or industrial tools are better suited to fiber lasers for high-contrast, wear-resistant identification. - Sensitive coated buttons, medical-grade tubing and catheters call for the low-heat UV approach to avoid deformation. - Hangzhou Kechuang Mark Technology Co.,Ltd says it has more than 40 patents and software copyrights. - The company also says it is a national high-tech enterprise, holds a weight calibration certificate and has passed national CMA testing. - Kecmark offers material sampling and testing to check wavelength compatibility before deployment. - The company is a member of the China Machine Vision Industry Alliance.

Between the lines: - The release is less about one machine and more about a selection framework tied to material physics. - Kecmark is trying to position technical testing and integration support as part of the product, not an add-on service. - The emphasis on medical, automotive and packaging use cases suggests the company is targeting industries where mark quality and compliance carry higher stakes.

What's next: - Manufacturers will likely choose between CO2, fiber and UV systems based on substrate absorption, heat tolerance and line speed. - Kecmark says its technical team can support sampling, testing and integration into existing automated workflows. - The company is directing customers to its website and social channels for industrial laser marking information. - Contact information in the release includes +86 400 181 8727.
