Yes. Flying units can be supplied with I/O and PLC communication over common industrial protocols for start-stop interlock, fault feedback, mark-complete c
Yes. Format is set by the f-theta focal length; large areas need a large-field lens or dynamic focusing, or you move to a large-format cutting machine. Our
Yes. UV energy density is finely controllable, so grayscale artwork or layered vectors scanned at different depths create stepped levels that read as three
Yes. Cable is extruded continuously, so an encoder reads actual line speed and the system triggers cyclically at a set interval - every metre, for example
Inspection and marking can be combined. The vision system applies defined rules - dimensions, presence of features, missing material - skips any part that
The control software is JCZ EzCad (EzCad2 or EzCad3), whose interface can be switched between languages, and routine actions can be exposed on a simplified
It can, but it is manageable. Temperature swings affect two things: chiller drift changing laser output stability, and thermal expansion of the structure s
Fiber and UV sources are rated in operating hours and normally reach tens of thousands of hours. The real consumables are galvo and lens contamination plus
A single pass typically removes tens of micrometres to around 0.1 mm; depth is built up by layering. Each layer's slag must be blown clear or the next laye
Yes, this is a classic UV advantage. The coating and the substrate absorb 355 nm differently, and UV pulse energy is finely controllable with little heat s
It depends on the power configuration. Voltage swings are normal on industrial sites and there are two fixes: specify an internal supply with a wide input
It is decisive. A smaller, more symmetric Gaussian spot gives sharper character edges and better legibility at the same character height. Our UV platform f
Yes. Templates are stored in the software and recalled in seconds. Better still, a sensor or barcode scanner can identify the product and load its template
Yes. Leather absorbs strongly at 10.6 micrometres, and controlling power percentage with grayscale mapping produces depth layering and a three-dimensional
A distinction is needed: PMMA absorbs poorly at 355 nm, so UV is a weak choice on acrylic. CO2 is the usual answer - it melts and re-solidifies the surface
Flutter causes two problems: focus drift and position drift. Depth of field and a pressure roller or vacuum hold-down fix the first; encoder tracking and a
Vision recognition runs in milliseconds and is rarely the bottleneck; marking time and load-unload cycle usually dominate. Our vision platform takes one im
The mark itself can satisfy UDI requirements for permanence and legibility - UV marks do not rub off and survive routine sterilisation. Compliance is a sys
Yes. The encoder measures line speed continuously and the controller compensates in real time, so speed changes do not distort the code. Missed marks are p
Yes. The rotary axis converts angular displacement into linear travel, and the software's cylindrical unwrap function lays the artwork continuously around
Retrofitting is the most common flying application. You need three things: an encoder or measuring wheel on the conveyor, a bracket and guarding for the ma
UV cold processing is designed for thin materials, but it has to stay under threshold. Power, frequency and scan speed together set the energy density per
Continuous duty tests three things: laser thermal management, galvo drift and long-run controller stability. Our flying machines use industrial-grade compo
Portable units are designed for one-person carry and immediate use on arrival. The all-in-one cabinet ships in a carry case or trolley case and only needs
UV modifies the surface layer itself rather than depositing a coating, so normal abrasion does not remove it. Durability is ultimately bounded by the subst
Charring is a function of temperature and dwell time. The fix is higher speed, lower power percentage and fewer passes so heat cannot spread sideways, plus
Glass and ceramic absorb poorly at 1064 nm, so fiber either fails to mark or marks by thermal stress, which chips the edge, whitens it and can leave micro
Throughput is set by line speed and code content, not by the laser alone. For a single date code of roughly 10 to 15 characters, flying marking typically l
That is exactly what vision marking is for. The camera is calibrated, template matching captures each part's actual position and rotation, the offset is ha
Our UV platform focuses to a 15 micrometre spot, and legible character heights down to about 0.3 mm remain scan-stable in practice. The real limit is set b
Yes. Variable data is created at trigger time: date, shift and serial number can auto-increment by rule, or be read line by line from a database or text fi
Depth is governed by single-pulse energy and pass count, not by wattage alone. At a given power, lowering the frequency raises pulse energy and deepens eac
UV at 355 nm breaks molecular bonds photochemically rather than melting the surface, so the heat-affected zone is minimal and the yellowing typical of fibe
Yes, provided the encoder tracks line speed. The encoder feeds conveyor displacement to the controller in real time, and the galvo applies vector compensat
The QCW laser spot welder handles batteries, sensors, jewellery and thin sheets with low heat input and little distortion. Compared with TIG.
The flying laser marker codes moving parts online (date, batch, serial) in sync with an encoder - for pipes, cable, caps and food packaging lines.
The vision laser marker uses a CCD camera to read part position and angle and auto-compensates - for irregular parts and multi-part marking.
The CO2 laser marker uses 10.6um for organics like wood, leather, paper and acrylic - crisp engraving and light cutting. Principle and materials covered.
The fiber laser marker uses 1064nm with high metal absorption: deep engraving, black marking and MOPA colour on stainless, aluminium and copper.
The UV laser marker uses a 355nm cold source with almost no heat-affected zone - high-contrast permanent marks on glass, plastic and chips.
How laser marking cuts consumables and improves traceability, with selection notes for fiber, UV, CO2, vision and flying marking machines.
How CE certification (LVD + MD) applies to laser marking machines exported to the EU, plus what overseas buyers should check before shipping.
Lens cleaning and care for fiber, UV and CO2 laser markers: intervals, tools, the four most common mistakes, and how to spot a dirty lens.
Laser marking selection starts with material: fiber 1064nm for metal, UV 355nm for glass and plastic, CO2 for wood and leather. Selection table included.
How 1064nm fiber, 355nm UV and 10.6um CO2 laser marking work, which materials each suits, and a wavelength selection table.
Laser marking compared with mechanical scribing, chemical etching, hot stamping and inkjet on consumables, durability and precision.
A weak mark is usually a dirty lens or poor cooling, not a failed laser. Daily, weekly and monthly checklists plus wear-part intervals.
