Kufa kudula ndi njira yofunika kwambiri popanga zilembo zodzimatira. Zimaphatikizapo kudula malemba m'mawonekedwe ndi makulidwe enieni omwe amalola kuti agwiritsidwe ntchito mosavuta kumalo osiyanasiyana. Komabe, njira yodula kufa ikhoza kukumana ndi zovuta zina zomwe zimakhudza ubwino ndi mphamvu ya kupanga malemba. Zinthu zazikulu zomwe zimakhudza kudulidwa kufa kwa zilembo zodzimatira zitha kufotokozedwa mwachidule m'mbali zitatu zazikulu.: lembani zida zapamwamba, zodzikongoletsera zokha, ndi zida zokha. M'nkhaniyi, timafufuza mbali izi ndikukambirana njira zothetsera mavuto.
1. Lembetsani zakuthupi:
Zomwe zili pamwamba pa chizindikiro chodziphatika zimagwira ntchito yofunika kwambiri pakufa. Zida zosiyanasiyana zimakhala ndi zinthu zosiyanasiyana zomwe zimakhudza njira yodulira. Pali zinthu zitatu zazikulu: mtundu wa zinthu zapamwamba, the strength of the surface material, and the thickness of the surface material.
a) Surface material type:
The types of surface materials used in self-adhesive labels vary widely, and each material has unique characteristics that affect die-cutting, mainly including paper and film.
Zolemba Papepala: Paper labels are commonly used and come in a variety of weights and finishes. Komabe, they are more prone to tearing or folding during the die-cutting process, especially if the paper is thin or fragile. When we analyze samples, we often see that some labels have burrs, which is caused by natural fracture due to the thick fibers of the material itself. Choncho, it is important to choose the proper paper thickness and quality for the intended application to ensure smooth die-cutting. Based on the die-cutting principle of paper materials, ndi kuganizira kuvala kwa tsamba, mbali ya pepala yopalasa mapepala nthawi zambiri imakhala yaikulu. Chifukwa ngodya ndi yayikulu, extrusion mapindikidwe zinthu pa kufa kudula ndi lalikulu, ndipo mphamvu yolekanitsa mu njira yopingasa imathandizira kulekanitsa zipangizo.
Zolemba zamakanema: Mafilimu amaika zofunikira kwambiri pa njira yodula kufa kuposa zipangizo zamapepala. Ambiri ntchito filimu kudziona zomatira pamwamba zipangizo makamaka monga: PE, PP, PE, polyolefin, Zithunzi za PVC, PS, ndi zina., ndi kulimba, kukana chinyezi ndi kukana mankhwala. Zidazi nthawi zambiri zimakhala zosinthika komanso sizing'ambika, kuwapanga kukhala oyenera kupanga mapangidwe ovuta kwambiri odulidwa. Komabe, Zolemba zamakanema zimakhala zovuta kuzidula molondola chifukwa cha kusinthasintha kwake kapena kukumbukira. Pachifukwa ichi, tsamba la filimu yodula-kufa liyenera kukhala lakuthwa, kuuma kwakukulu, ndi ngodya yaing'ono, kawirikawiri 37 ° mpaka 75 °. Kang'ono kakang'ono, kuthwa kwa mpeni ndipo kumakhala kosavuta kufa kudula. Ngati mumagwiritsa ntchito chodulira chakufa chokhala ndi ngodya yayikulu, sikungovuta kufa-kudula, koma ngati tsambalo silili lakuthwa, zinthu zapamwamba sizidzadulidwa ndipo pepala lapansi lidzasweka poyamba, ndipo m'mphepete mwa cholembedwa chomalizidwacho mudzazengereza. Chifukwa cha glue.
Mwachidule, kulondola kwa filimu yodulidwa-kufa ndi yaikulu kuposa ya zipangizo zamapepala, chifukwa chake zida zamakanema odulidwa zili ndi zofunika zina pakulondola kwa zida, di-cut plate mwatsatanetsatane ndi pepala lothandizira.
b) Mphamvu ya pamwamba:
Kulimba kwa chizindikiro cha facestock ndi chinthu china chofunikira chomwe chikukhudza kudula kufa. Zimatanthawuza kukhoza kwa zinthu kupirira mphamvu yodula yomwe imagwiritsidwa ntchito ndi zida zodulira. Nazi malingaliro ena:
Kukana misozi: Zolemba zomwe zimafuna kukana misozi kwambiri, monga za mafakitale kapena ntchito zakunja, ziyenera kupangidwa ndi zipangizo zokhala ndi mphamvu zokwanira. Zida monga mafilimu opangira kapena mapepala olimbikitsidwa angapereke kukana koyenera kwa misozi kuti atsimikizidwe kukhala oyera, mabala enieni pa kudula kufa.
Kumeta ubweya Mphamvu: Kumeta ubweya wa mphamvu kumatanthawuza kukana kwa chinthu ku mphamvu yodulira yofanana ndi pamwamba pake. Zolemba zokhala ndi mphamvu zometa ubweya wambiri sizitha kupindika kapena kung'ambika panthawi yodula. Kusankha chinthu chokhala ndi mphamvu yometa ubweya woyenerera kudzatsimikizira zotsatira zolondola komanso zosagwirizana.
c) Makulidwe a zinthu zapamtunda:
Kusasinthika kwa makulidwe ndikofunikira kuti muwonetsetse kuya kofanana kwa kudula ndikupewa zovuta monga kudula kosakwanira kapena mphamvu yodula kwambiri.. Zolemba zokhala ndi makulidwe azinthu zosagwirizana zimatha kuyambitsa kusiyana pakuzama kwa kudula, kukhudza ubwino ndi maonekedwe a malembo odulidwa. Kuphatikiza apo, makulidwe azinthu amakhudza mwachindunji kuya kwa kufa-kudula. Kukhuthala kwa zinthu, ndikosavuta kufa-kudula, ndi mosemphanitsa, kuonda kwake ndiko kudula kufa, ndizovuta kwambiri.
Zida zosiyanasiyana zodulira kufa zimatha kukhala ndi malire pa makulidwe apamwamba azinthu zomwe angakwanitse. Ndikofunikira kulingalira za zida ndikusankha zida zolembera mkati mwa makulidwe omwe akulimbikitsidwa kuti muwonetsetse kuti ntchito yabwino yodula kufa.
2. Zodzimanga zokha
Pali zomatira ziwiri zomwe zimagwiritsidwa ntchito kwambiri pazinthu zodzimatira: madzi latex ndi otentha kusungunula zomatira.
Madzi a latex amapangidwa ndi tinthu ta polima tomwazika m'madzi, ndipo mphamvu yogwirizana ndiyosavuta kupatukana ndi filimuyo. Zomatira zotentha zosungunuka zimapangidwa ndi zinthu ngati mphira zomwe zimakhala zogwirizana kwambiri, ndipo n'zovuta kulekanitsa mafilimu omatira. Chifukwa champhamvu fluidity ya otentha-kusungunuka zomatira, ngati malemba ang'onoang'ono amasindikizidwa pamwamba pa zomatira, zomatira zidzayenderera pamene chizindikirocho chili ndi kusuntha pang'ono panthawi yophatikiza ndi kufa-kudula., kuchititsa kusindikiza pa izo. Mawu omwe ali pazenera amasinthidwa pang'ono, kupotozedwa, kapena mdima. Kuphatikiza apo, zomatira zotentha zosungunuka zimakhudzidwa mosavuta ndi kutentha. Nthawi zambiri, pamene kutentha kwa msonkhano kuli pansi pa 15 ° C, mphamvu yomasulidwa ya zomatira zotentha zosungunuka zidzachepa mofulumira. Choncho, m'nyengo yozizira, zomatira zotentha zosungunuka ndizosavuta kwambiri ku vuto la zizindikiro zowuluka.
Choncho, tikulimbikitsidwa kuti makampani osindikiza zilembo ayesetse kuti asasankhe zomatira zotentha zosungunuka ndi madzi amphamvu, koma sankhani zida zamadzi zokhala ndi madzi ofooka. Nthawi yomweyo, ngakhale mutasankha zakuthupi za hydrosol, muyeneranso kulabadira makulidwe ❖ kuyanika a zomatira wosanjikiza. Chifukwa kaya ndi zomatira zotentha zosungunuka kapena hydrosol, ngati zokutira zomatira ndi wandiweyani kwambiri, zingayambitse zomatira kuyenda pang'ono, kupangitsa kuti mawu ang'onoang'ono osindikizidwa asokonezeke.
3. Zida zokha
Kulondola komanso kuyanjanitsa kwa chodulira chakufa ndikofunikira kuti mupeze mabala olondola komanso osasinthasintha. Makinawo ayenera kusinthidwa bwino ndikuyanjanitsidwa kuti awonetsetse kuti chida choduliracho chili bwino komanso cholembera. Mavuto olakwika angayambitse kudulidwa kosakwanira, mawonekedwe osakhazikika, kapena zolembedwa molakwika, zomwe zingakhudze mtundu wonse wa lebulo yomalizidwa. Kukonza nthawi zonse ndikusintha makina ndikutsatira malangizo a wopanga ndikofunikira kuti mukhale olondola komanso ogwirizana..
Komanso, kukakamiza odulidwa ndi makonda othamanga pa chodula chakufa kuyenera kusinthidwa moyenera kuti azitha kugwiritsa ntchito zilembo ndi zomatira zomwe zikugwiritsidwa ntchito.. Kuthamanga kosakwanira kodulira kungayambitse kudulidwa kosakwanira kapena kuvutikira kulekanitsa chizindikirocho kuchokera ku liner. Kuthamanga kwambiri kodula kumatha kufooketsa, kung'amba kapena kuwonongeka zilembo. Momwemonso, liwiro lodulira liyenera kukonzedwa kuti zitsimikizike kuti mabala oyera popanda kusokoneza kulondola. Kuwongolera koyenera kwa kuthamanga ndi kuthamanga kwa magawo otengera zolemba ndi zomatira ndikofunikira kuti tipeze zotsatira zofananira komanso zapamwamba kwambiri..
Ubwino ndi chikhalidwe cha zida zodulira zomwe zimagwiritsidwa ntchito podula kufa zimakhudza kwambiri njira yodulira. Masamba odulira osawoneka bwino kapena owonongeka amatha kupangitsa kuti ikhale yosadulidwa bwino, kuchuluka kwa mphamvu zodulira, kapena kuwonongeka kwa zinthu zolembera. Kuyendera nthawi zonse ndi kukonza zida zodulira, kuphatikizapo kusintha masamba pakufunika, n'kofunika kuonetsetsa mulingo woyenera kudula ntchito. Kugwiritsa ntchito tsamba labwino ndikuganiziranso kapangidwe kake kachingwe kazinthu zolembera zomwe zikugwiritsidwa ntchito kungathandizenso kuwongolera bwino komanso kulondola..
Poganizira mbali izi ndikugwiritsa ntchito mayankho omwe aperekedwa, opanga amatha kuthana ndi zovuta zochepetsera kufa ndikukwaniritsa zokhazikika, zodzikongoletsera zolondola komanso zapamwamba kwambiri. Kugwirizana ndi ogulitsa zinthu, opanga zomatira, okonza nkhungu ndi akatswiri a zida angaperekenso chidziwitso chofunikira komanso chithandizo chothandizira kukonza njira yodulira. Kupyolera mu tcheru ku mwatsatanetsatane ndi mosalekeza kusintha, opanga amatha kuwonetsetsa kuti akupanga bwino ndikukwaniritsa zosowa zamitundu yosiyanasiyana yamalemba.
