1.Dab tsi yog nws cov qauv kev ua haujlwm thiab cov yam ntxwv?
Selective ablation:
Lub zog siab ntawm lub laser beam yog absorbed los ntawm txheej (xim / yas txheej), ua rau nws sai sai thiab vaporize (ablation).
Qhov zoo tshaj plaws, lub zog laser yog tswj tau meej, tshem tawm tsuas yog cov txheej txheej uas tsis muaj melting los yog ua rau lub hauv paus galvanized lossis aluminized zinc steel ntawv.
Qhov kawg tshwm sim yog qhov tshwm sim ntawm cov xim hlau -lustered hauv qab txheej, tsim kom muaj ib tug siab - txawv txawv txawv nrog ib puag ncig xim txheej. Cov xim ntawm txheej hlau nws tus kheej (nyiaj-dawb ntawm zinc, ci dawb ntawm aluminized zinc) txiav txim siab xim tom qab ntawm tus qauv.
Visual effect:
Cov qauv muaj "intaglio" cov nyhuv vim tias qhov sib txawv me ntsis nyob tom qab txheej txheej raug tshem tawm.
Cov xim muaj qhov sib txawv heev, ua rau nws tsim nyog rau kev tsim cov logos, cov lej cim, QR cov lej, cov kab zoo nkauj, cov qauv kos duab, thiab lwm yam.
2.Yuav ua li cas xaiv hom laser?
Fiber lasers / MOPA fiber ntau lasers: Tam sim no qhov kev xaiv zoo tshaj plaws. Lawv lub wavelength (~ 1064nm) tau zoo absorbed los ntawm feem ntau cov organic coatings, thiab cov mem tes tswj tau yooj yim "txias ua", txo cov cua sov- thaj tsam cuam tshuam thiab tiv thaiv scorching thiab substrate overheating.
CO2 lasers: kuj tuaj yeem siv rau qee cov txheej txheem, tab sis cov nyhuv tshav kub yuav ntau dua, uas ua rau tsis tiav ablation lossis ntug carbonization ntawm qee cov txheej txheem.
Ultraviolet lasers: Tsis tshua muaj siab precision thiab tsawg tshav kub nyhuv, tab sis cov cuab yeej siv siab; feem ntau yog siv rau cov cim zoo heev.
3.Dab tsi yog qhov cuam tshuam ntawm txheej txheej?
Polyester (PE) thiab silicone- hloov polyester (SMP): Feem ntau siv, kuj yooj yim rau laser engrave, nrog cov txiaj ntsig pom tseeb.
Fluorocarbon (PVDF): Vim nws cov huab cua zoo heev thiab kev ruaj ntseg tshuaj, nws nyuaj rau ablate. Nws yuav tsum muaj zog laser ntau dua los yog qhov tsis zoo, thiab cov npoo yuav tsis ntse npaum li cov txheej polyester.
Xim: Tsaus coatings (tshwj xeeb yog dub) nqus laser zog ntau dua thiab yooj yim rau kos. Lub teeb- xim lossis xim hlau txheej (muaj cov hmoov txhuas) muaj kev cuam tshuam siab, yuav tsum tau kho qhov ntsuas kom ua tau zoo.
4.Yuav ua li cas cov txheej txheem yuav optimized?
Lub zog, ceev, zaus, thiab sau qhov sib txawv: Cov no yuav tsum tau hloov kho meej rau cov hom txheej txheej, xim, thiab thicknesses. Lub hom phiaj yog kom huv si tshem cov txheej nrog lub zog qis tshaj plaws thaum:
Minimizing thermal cuam tshuam: Tiv thaiv yellowing thiab carbonization ntawm txheej txheej.
Tiv thaiv lub substrate: Tsis txhob ablation ntau dhau uas tuaj yeem ua rau cov zinc txheej puas thiab cuam tshuam corrosion kuj.
Ua kom cov qauv zoo: Cov kab ntshiab thiab zoo sib xws.
5.Dab tsi yog qhov zoo thiab muaj peev xwm teeb meem?
Qhov zoo:
Tsis yog -kev sib cuag, siab precision: Muaj peev xwm engraving complex graphics, zoo kab, thiab cov ntawv me me.
Kev cim ruaj khov: Cov qauv yog hnav- tiv taus thiab tsis yooj yim tev tawm.
Tsis muaj tus cwj mem consumables yuav tsum tau: Ib puag ncig tus phooj ywg thiab nrog cov nqi khiav lag luam qis.
Automation integration: Ib qho yooj yim rau kev koom ua ke rau hauv cov kab ntau lawm rau kev kos npe online.
Kev kho tus kheej thiab tiv thaiv- cuav: Zoo tagnrho rau kev tsim khoom raws li kev txheeb xyuas, cim npe, thiab kho kom zoo nkauj.
Tej Yam Teeb Meem thiab Cov Teeb Meem (Yuav tsum tau soj ntsuam):
Kev Txhaum Cai Hauv Zos Kev Tiv Thaiv: Qhov no yog qhov teeb meem tseem ceeb tshaj plaws. Cov txheej tiv thaiv raug tshem tawm ntawm thaj chaw engraved, ua rau cov hlau raug (txawm tias txheej txheej galvanized) muaj kev cuam tshuam rau corrosion. Rau kev siv sab nraum zoov, kev ntsuas kev pheej hmoo yog qhov tsim nyog, lossis kev tiv thaiv ib puag ncig hauv cheeb tsam (xws li xeb ntshiab -cov tsho tiv thaiv) yuav tsum tau txiav txim siab tom qab kos duab.
Kev txwv xim thiab cuam tshuam: Tsuas yog qhov sib piv ntawm "thawj xim hlau vs. txheej xim" tuaj yeem ua tiav. Cov teebmeem xim lossis gradient tsis tuaj yeem tsim tau.
Substrate Damage Risk: Cov kev ntsuas tsis raug tuaj yeem ua rau melting, discoloration (heat oxidation), los yog perforation ntawm lub hauv paus hlau.
Hazardous fumes: Ablation ntawm txheej tsim cov pa taws thiab cov teeb meem, yuav tsum muaj lub tshuab ua pa zoo thiab pom zoo los tiv thaiv tus neeg teb xov tooj noj qab haus huv thiab ua kom lub ntsej muag huv.
Ceev thiab Nqi: Intricate, loj - cheeb tsam engraving qeeb, cuam tshuam ntau lawm efficiency.
