FAQS
- Industrial laser markers use a focused laser beam to permanently engrave, etch, or mark text, logos, serial numbers, barcodes, QR codes, and graphics directly onto product surfaces. Unlike labels or ink printing, laser marks are permanent, resistant to abrasion, chemicals, and heat, and do not add any consumable material to the part. Laser marking is used for product identification, traceability (serial numbers, lot codes, date codes), regulatory compliance (UDI codes on medical devices, VIN marking in automotive), branding, and anti-counterfeiting. Common industries include automotive, aerospace, medical devices, electronics, and food and beverage packaging.
- The three primary laser marking technologies are fiber lasers, CO2 lasers, and UV (ultraviolet) lasers — each suited to different materials. Fiber lasers operate at approximately 1064 nm wavelength and are the most versatile and widely used — they mark metals (steel, aluminum, titanium, copper), engineered plastics, and some ceramics with high speed, contrast, and precision. CO2 lasers operate at 10.6 µm wavelength and excel at marking organic materials — wood, glass, paper, leather, acrylic, and many plastics — as well as coated metals. UV lasers (355 nm) produce a very fine, cold mark with minimal heat-affected zone, making them ideal for heat-sensitive materials like medical plastics, thin films, and electronics components where thermal damage must be avoided. Selecting the right laser type starts with the material to be marked and the desired mark quality.
- Yes, laser markers are commonly integrated directly into automated production lines for inline marking at production speed. Fixed-mount laser marking heads are positioned over or alongside a conveyor, and the PLC triggers the marker when a product arrives at the marking station — typically detected by a photoeye or encoder signal. The mark content (serial numbers, date codes, batch information) is sent dynamically from the PLC, MES, or ERP system so each part receives unique data. For high-speed applications, the laser marks on-the-fly as the product moves past the marking window without stopping the line. Integration requires coordination between the laser controller, PLC, and vision system (if mark verification is included). Most industrial laser markers support standard communication protocols — Ethernet/IP, PROFINET, RS-232, and TCP/IP — for seamless integration with existing automation infrastructure.
- Mark verification ensures that every marked code is readable and meets quality standards — critical for traceability and regulatory compliance. Automated mark verification typically uses a vision system or barcode scanner positioned immediately after the laser marking station. For 1D and 2D barcodes, the verifier grades the mark quality according to ISO/IEC standards (ISO 15415 for 2D, ISO 15416 for 1D) and assigns a grade from A (highest) to F (fail) based on contrast, cell uniformity, quiet zones, and decodability. For human-readable text, optical character recognition (OCR) or optical character verification (OCV) systems confirm the content matches the intended mark. Integrating verification directly into the production line ensures that no unmarked or illegibly marked product passes downstream, enabling immediate re-marking or rejection. This closed-loop approach is required in industries with strict traceability mandates such as medical devices, automotive, and aerospace.
