1. CO₂ Laser Marking
Lub wavelengthNtev: 10.6 μm (far infrared)
Txoj Cai: Tsim los ntawm cov pa tawm, cov nqaj yog tsom mus rau cov khoom nto, cua sov thiab vaporizing nws los ua cov cim.
Cov ntaub ntawv siv tau:
Tsis yog-hlau: ntoo, ntawv, yas, roj hmab, tawv, iav, ceramics, thiab lwm yam.
Tsis haum rau kev kos ncaj qha rau ntawm cov hlau liab qab (tshwj tsis yog coated).
Qhov zoo:
Kev nqus tau siab ntawm cov hlau tsis yog -hlau, ntshiab engraving
Zoo beam zoo, ruaj khov ua haujlwm
Mature technology, tus nqi qis
Qhov tsis zoo:
Tsawg efficiency (electro-kev hloov kho qhov muag<10%)
Tsis zoo rau kev sib sib zog nqus hlau cim
Tej kev siv: Ntim (khoom noj khoom haus, lub raj mis dej haus, lub thawv tshuaj), cov khoom siv ntoo, cov khoom tawv tawv, iav engraving.
2. Fiber Laser npav
Lub wavelength1064nm (ze infrared)
Txoj Cai: Siv fiber ntau-raws li electro- hloov kho qhov muag los tsim cov kab hluav taws xob siab zog laser, ncaj qha rau ntawm cov khoom nto.
Cov ntaub ntawv siv tau:
Hlau: stainless hlau, txhuas, tooj liab, hlau, titanium, magnesium, thiab lwm yam.
Qee yam tsis yog-hlau: yas, tawv roj hmab (nrog additives)
Qhov zoo:
High conversion efficiency (>30%), kev siv hluav taws xob tsawg
Beam zoo heev, ultra-fine focus, meej heev
Kev tu-dawb, lub neej ntev (Ntau dua lossis sib npaug li 100,000 teev)
Fast marking ceev, haum rau huab hwm coj ntau lawm
Qhov tsis zoo:
Kev txwv tsis pub cuam tshuam rau cov ntaub ntawv pob tshab (xws li iav) thiab qee qhov tsis yog -hlau
Cov cuab yeej siv siab dua piv rau CO₂
Tej kev siv: Hlau qhov chaw coding, hluav taws xob Cheebtsam, IC chips, automotive qhov chaw, mobile xov tooj accessories, cov cuab yeej, hniav nyiaj hniav kub.
3. Diode Laser Marking
Lub wavelength808nm, 915nm, 980nm (ze infrared)
Txoj Cai: Siv semiconductor lasers ncaj qha emit los yog twj tso kua mis muaju los tsim laser, ces tsom rau kev kos.
Cov ntaub ntawv siv tau:
Plastics, tawv, qee yam hlau (limited efficiency)
Qhov zoo:
Compact loj, tus nqi qis
Pib nrawm- nce, lub neej ua haujlwm ntev
Portable system muaj
Qhov tsis zoo:
Tsawg zog, qis zog ceev
Cov kab teeb tsis zoo, tsis muaj zog ua kom pom tseeb
Tsawg dua piv rau fiber ntau thiab CO₂
Tej kev siv: Cov khoom siv hluav taws xob me me, cov khoom siv yas, cov khoom siv hluav taws xob tsawg, - cov nqi cim kev daws teeb meem.
