Laser engraving thiab laser marking yog ob qho tib si dav siv cov txheej txheem kev lag luam uas siv cov kab teeb tsom laser los hloov cov khoom nto. Thaum lawv tuaj yeem tshwm sim zoo sib xws, lawv txawv hauvmechanism, qhov tob, kev siv, thiab - thuam- hauvhom kev phom sij uas lawv tsim, uas cuam tshuam ncaj qhakev nyab xeeb thiab kev tiv thaiv, tshwj xeeb tshaj yog rau qhov muag.
1. Qhov txawv tseem ceeb: Laser Engraving vs. Laser Marking
| Feature | Laser Engraving | Laser Marking |
|---|---|---|
| Txheej txheem | Vaporizes cov ntaub ntawv los tsim kom sib sib zog nqus, recessed cim | Hloov cov khoom nto (xws li, hloov xim, oxidation) yam tsis muaj kev tshem tawm cov khoom tseem ceeb |
| Qhov tob | Sib sib zog nqus (txog ntau millimeters) | Plab los yog nto -level (microns) |
| Hom Laser | Feem ntau siab - fais fab CO₂ (10.6 μm), fiber ntau (1064 nm), lossis lasers pulsed | Fiber, UV, lossis lasers ntsuab; qis nruab nrab lub zog tab sis feem ntau siab ncov lub zog hauv pulses |
| Khoom siv | Ntoo, acrylic, hlau, iav, tawv | Hlau, yas, anodized txhuas, khoom siv kho mob |
| Daim ntawv thov | Khoom plig tus kheej, pwm, sib sib zog nqus- txiav kos npe | Serial tooj, barcodes, QR codes, kho mob traceability |
💡 Simple analogy:
Kev kos duab=carvingrau hauv cov khoom.
Kos npe=brandingqhov chaw.
2. Muaj xwm txheej tshwm sim
Ob qhov txheej txheem ua rau muaj kev phom sij loj rau kev ua haujlwm:
A. Optical Radiation (Qhov muag & tawv nqaij Risk)
Direct lossis reflected laser beamstuaj yeem ua rau lub qhov muag puas sai sai (retinal burns, corneal raug mob).
Wavelength tseem ceeb:
CO₂ lasers (10,600 nm): Feem ntau absorbed los ntawm cornea → pheej hmoo ntawm pob txha kub hnyiab.
Fiber / Nd: YAG lasers (1064 nm): Nkag mus rau retina → kev pheej hmoo ntawm qhov muag tsis pom mus tas li.
UV lasers (355nm): tuaj yeem ua rau photokeratitis ("welder's flash") thiab cataracts.
B. Fumes thiab Particulates
Kev kos duab (tshwj xeeb tshaj yog ntawm cov yas, coated hlau, lossis cov khoom sib xyaw) tso tawmcov pa phem(piv txwv li, cyanide los ntawm ABS, formaldehyde los ntawm ntoo).
Kev kos npe tuaj yeem tsim cov pa taws tsawg dua tab sis tseem tuaj yeem tawmhlau oxide nanoparticles(piv txwv li, los ntawm stainless hlau).
C. Hluav taws kub
Siab - lub zog engraving lasers tuaj yeem ua rau cov khoom siv hluav taws xob (daim ntawv, ntoo, ntaub).
3. Kev Tiv Thaiv Qhov Muag: Qhov Ntsuas Kev Nyab Xeeb Tseem Ceeb
Vim ob txoj kev sivClass 4 lasers(siab- zog, txaus ntshai),certified laser eyewear yog yuav tsum tau.
Yuav tsum muaj kev tiv thaiv zoo:
Sib piv cov wavelength: Cov tsom iav yuav tsum raug ntsuas rau cov laser tshwj xeeb hauv kev siv (xws li, 1064 nm rau fiber ntau lasers, 10,600 nm rau CO₂).
Txaus Optical Density (OD): Yuav tsum txo cov nqaj siv hauv qab qhov txwv tsis pub muaj kev nyab xeeb (piv txwv li, OD 5+ rau cov fiber ntau lasers).
Daim ntawv pov thawj: Hauv Tebchaws Europe,TS EN 207yog tus qauv tseem ceeb rau laser tiv thaiv tsom iav siv nrog ncaj los yog diffusely reflected beams.
✅ Piv txwv:
Fiber laser marker ua haujlwm ntawm 1064 nm yuav tsum tau tsom iav nrogEN 207 ntawv pov thawj, cim rau"D L5"(rau nruam nthwv dej) los yog"R L5"(rau cov mem tes lasers) ntawm 1064 nm.
4. JTBYShield: Certified Protection rau Industrial Lasers
JTBYShieldmuabEN 207-certified laser tsom iav tsom iavtsim tshwj xeeb rau kev siv hauv kev lag luam xws li engraving thiab kos npe:
Cov qauv rau fiber ntau lasers: Tiv thaiv 1064 nm nrog OD 5+ lossis siab dua (piv txwv li, EN 207 R L5 kev ntsuas rau kev ua haujlwm ntawm tes).
Cov qauv rau CO₂ lasers: Shield tiv thaiv 10,600 nm nrog IR filtering tsim nyog.
Kev tsim qauv ruaj khov: Resistant rau khawb, cuam tshuam, thiab tshuaj txau.
Clear labeling: Txhua khub qhia meej txog kev tiv thaiv ib puag ncig EN 207, yog li cov neeg siv tuaj yeem txheeb xyuas qhov sib xws.
⚠️ Tseem ceeb: Tsis txhob siv generic "laser tsom iav" yam tsis tau lees paub EN 207 (los yog ANSI Z136) ntawv pov thawj. Tsis yog- cov looj tsom iav uas tau lees paub yuav tshwm sim tsaus tab sis muajxoom tiag tiag tiv thaivntawm qhov tseem ceeb wavelengths.
