Makampani onyamula katundu amadalira kwambiri njira zosindikizira zokongoletsa ndi mabotolo amtundu ndi zotengera.Komabe, kusindikiza pagalasi motsutsana ndi pulasitiki kumafuna njira zosiyana kwambiri chifukwa cha zinthu zapadera komanso njira zopangira zinthu zilizonse.
Kusindikiza pa Mabotolo agalasi
Mabotolo agalasi amapangidwa makamaka pogwiritsa ntchito njira yowomba, komwemagalasi osungunula amawombedwa ndikuuzira mu nkhungu kupanga mawonekedwe a chidebecho. Kupanga kutentha kwakukuluku kumapangitsa kusindikiza pazenera kukhala njira yodzikongoletsera yodziwika bwino yagalasi.
Kusindikiza pazenera kumagwiritsa ntchito chinsalu cha mesh chabwino chokhala ndi zojambula zomwe zimayikidwa mwachindunji pa botolo lagalasi. Inki kenako imafinyidwa m'malo otseguka a skrini, ndikusamutsira chithunzicho pagalasi. Izi zimapanga filimu ya inki yokwezeka yomwe imauma mofulumira kutentha kwambiri. Kusindikiza pazenera kumapangitsa kuti pakhale chithunzi chowoneka bwino, chowoneka bwino pagalasi ndi zomangira za inki bwino ndi malo oterera.
Njira yokongoletsera botolo la galasi nthawi zambiri imapezeka pamene mabotolo akadali otentha kuchokera ku kupanga, zomwe zimathandiza kuti inki zigwirizane ndi kuchiritsa mofulumira. Izi zimatchedwa "hot stamping". Mabotolo osindikizidwa amalowetsedwa mu uvuni kuti aziziziritsa pang'onopang'ono ndikupewa kusweka kwa kutentha.
Njira zina zosindikizira magalasi zimaphatikizapoChokongoletsera chagalasi chowotcha ndi galasi losindikizidwa ndi UVg. Powotcha ng'anjo, inki za ceramic frit zimasindikizidwa kapena kugwiritsidwa ntchito ngati ma decals mabotolo asanadyetsedwe mu uvuni wotentha kwambiri. Kutentha kwakukulu kumapangitsa kuti galasi la pigment lizimitsidwa mpaka kalekale. Kwa machiritso a UV, ma inki osamva ku UV amasindikizidwa pazenera ndipo nthawi yomweyo amachiritsidwa pansi pa kuwala kwa ultraviolet.
Kusindikiza pa Mabotolo Apulasitiki
Mosiyana ndi galasi,mabotolo apulasitiki amapangidwa ndi extrusion blowing akamaumba, jekeseni nkhonya akamaumba, kapena kutambasula kuwomba kuumba pa kutentha otsika. Chotsatira chake, mapulasitiki ali ndi zofunikira zosiyanasiyana zomatira inki ndi njira zochiritsira.
Kusindikiza kwa Flexographic kumagwiritsidwa ntchito kwambiri kukongoletsa botolo la pulasitiki.Njirayi imagwiritsa ntchito chithunzi chokwezeka pa mbale yosinthika ya photopolymer yomwe imazungulira ndikulumikizana ndi gawo lapansi. Ma inki amadzimadzi amatengedwa ndi mbale, kusunthira molunjika pamwamba pa botolo, ndipo nthawi yomweyo amachiritsidwa ndi UV kapena kuwala kwa infrared.
Kusindikiza kwa Flexographic kumapambana pa kusindikiza pa malo opindika, opindika a mabotolo apulasitiki ndi zotengera.Ma mbale osinthika amalola kusamutsidwa kosasintha kwa zithunzi kuzinthu monga polyethylene terephthalate (PET), polypropylene (PP), ndi polyethylene yapamwamba kwambiri (HDPE). Inki za Flexographic zimagwirizana bwino ndi magawo apulasitiki omwe sakhala ndi porous.
Zosankha zina zosindikizira za pulasitiki zimaphatikizapo kusindikiza kwa rotogravure ndi zolemba zomatira.Rotogravure imagwiritsa ntchito silinda yachitsulo chojambulidwa kuti isamutse inki kuzinthu. Zimagwira ntchito bwino pamabotolo apulasitiki apamwamba kwambiri. Zolemba zimapereka kusinthasintha kokongoletsa thumba la pulasitiki, kulola zithunzi zatsatanetsatane, mawonekedwe, ndi zotsatira zapadera.
Kusankha pakati pa magalasi ndi mapulasitiki apulasitiki kumakhudza kwambiri njira zosindikizira zomwe zilipo. Podziwa zamtundu uliwonse ndi njira zopangira, okongoletsa mabotolo amatha kugwiritsa ntchito njira yabwino yosindikizira kuti akwaniritse mapangidwe olimba, okopa maso.
Kupititsa patsogolo luso la kupanga magalasi ndi pulasitiki komanso kupita patsogolo kwaukadaulo wosindikiza kudzakulitsa mwayi wolongedza.
