1. Kupangira jakisoni
Mfundo yaikulu ya jekeseni yopangira jekeseni ndi kuwonjezera zinthu zopangira zopyapyala kapena ufa mu hopper ya makina opangira jekeseni, ndipo zinthu zopangirazo zimatenthedwa ndikusungunuka kukhala madzimadzi. Motsogozedwa ndi screw kapena piston ya makina opangira jekeseni, imalowa m'bowo la nkhungu kudzera mu nozzle ndi njira yotsekera nkhungu ndipo imauma ndikuwoneka m'bowo la nkhungu. Zinthu zomwe zimakhudza ubwino wa jekeseni yopangira jekeseni: kuthamanga kwa jekeseni, nthawi yopangira jekeseni, ndi kutentha kwa jekeseni.
Zinthu zomwe zimachitika:
Ubwino:
(1) Kukonza zinthu mwachidule, kupanga zinthu mwachangu, komanso kugwiritsa ntchito zinthu zokha mosavuta.
(2) Imatha kupanga zigawo zapulasitiki zokhala ndi mawonekedwe ovuta, miyeso yolondola, ndi zitsulo kapena zoyikapo zinthu zosakhala zachitsulo.
(3) Ubwino wa chinthu chokhazikika.
(4) Mitundu yosiyanasiyana ya kusintha.
Zofooka:
(1) Mtengo wa zida zopangira jekeseni ndi wokwera kwambiri.
(2) Kapangidwe ka nkhungu yojambulira ndi kovuta.
(3) Mtengo wopangira ndi wokwera, nthawi yopangira ndi yayitali, ndipo siyoyenera kupanga zida zapulasitiki za chidutswa chimodzi ndi zazing'ono.
Ntchito:
Mu zinthu zamafakitale, zinthu zopangidwa ndi jekeseni zimaphatikizapo zinthu zakukhitchini (zitini za zinyalala, mbale, mabaketi, miphika, ziwiya za patebulo, ndi zotengera zosiyanasiyana), malo osungiramo zida zamagetsi (zowumitsira tsitsi, zotsukira vacuum, zosakaniza chakudya, ndi zina zotero), zoseweretsa ndi masewera, magalimoto. Zinthu zosiyanasiyana zamafakitale, mbali zina za zinthu zina zambiri, ndi zina zotero.
1) Ikani Kuumba kwa Jakisoni
Kuyika utomoni kumatanthauza kulowetsa utomoni pambuyo poyika zinthu zosiyanasiyana zomwe zakonzedwa kale mu nkhungu. Njira yopangira utomoni momwe zinthu zosungunuka zimamangiriridwa ku chinthu choyikamo ndi kulimba kuti zipange chinthu chophatikizana.
Zinthu zomwe zimachitika:
(1) Kuphatikiza koyambirira kwa zinthu zingapo zomwe zayikidwa kale kumapangitsa kuti kuphatikiza kwa chinthucho pambuyo pa uinjiniya kukhale komveka bwino.
(2) Kuphatikiza kwa kupangika kosavuta ndi kupindika kwa utomoni komanso kulimba, mphamvu, ndi kukana kutentha kwa chitsulo kungapangidwe kukhala zinthu zovuta komanso zokongola zophatikizika ndi zitsulo ndi pulasitiki.
(3) Makamaka pogwiritsa ntchito kuphatikiza kwa kutchinjiriza kwa utomoni ndi mphamvu ya chitsulo, zinthu zopangidwa ndi utomoni zimatha kukwaniritsa ntchito zoyambira za zinthu zamagetsi.
(4) Pa zinthu zolimba zopangidwa ndi zinthu zopindika komanso zopindika zopindika zomangirika pa mapepala otsekera a rabara, pambuyo poyika jekeseni pa substrate kuti apange chinthu chophatikizidwa, ntchito yovuta yokonza mphete yotsekera ikhoza kuchotsedwa, zomwe zimapangitsa kuti kuphatikiza kokhazikika kwa njira yotsatira kukhale kosavuta.
2) Kuumba jakisoni wamitundu iwiri
Kujambulira jakisoni wa mitundu iwiri kumatanthauza njira yojambulira poika mapulasitiki awiri amitundu yosiyanasiyana mu nkhungu imodzi. Kungapangitse pulasitiki kuoneka m'mitundu iwiri yosiyana komanso kungapangitse kuti zigawo za pulasitiki zikhale ndi mawonekedwe ofanana kapena mawonekedwe osasinthasintha a moiré, kuti ziwongolere kugwiritsidwa ntchito ndi kukongola kwa zigawo za pulasitiki.
Zinthu zomwe zimachitika:
(1) Zipangizo zapakati zimatha kugwiritsa ntchito zipangizo zotsika mphamvu kuti zichepetse kuthamanga kwa jakisoni.
(2) Poganizira za kuteteza chilengedwe, zinthu zofunika kwambiri zingagwiritsidwe ntchito zinthu zina zobwezerezedwanso.
(3) Malinga ndi makhalidwe osiyanasiyana ogwiritsira ntchito, mwachitsanzo, zipangizo zofewa zimagwiritsidwa ntchito pa chikopa cha zinthu zokhuthala, ndipo zipangizo zolimba zimagwiritsidwa ntchito pa zinthu zomangira. Kapena zipangizo zomangira zingagwiritse ntchito pulasitiki ya thovu kuti zichepetse kulemera.
(4) Zipangizo zoyambira zopanda khalidwe zingagwiritsidwe ntchito kuchepetsa ndalama.
(5) Chikopa kapena zinthu zapakati zimatha kupangidwa ndi zinthu zodula zokhala ndi mawonekedwe apadera pamwamba, monga kusokoneza mafunde a anti-electromagnetic, kuyendetsa magetsi kwambiri, ndi zinthu zina. Izi zitha kuwonjezera magwiridwe antchito a chinthucho.
(6) Kuphatikiza koyenera kwa zinthu zapakhungu ndi zinthu zapakati kungachepetse kupsinjika kotsala kwa zinthu zopangidwa ndi ulusi, ndikuwonjezera mphamvu ya makina kapena mawonekedwe a pamwamba pa chinthucho.
3) Njira Yopangira Injection ya Microfoam
Njira yopangira jekeseni ya Microfoam ndi ukadaulo watsopano wopangira jekeseni molondola. Chogulitsacho chimadzazidwa ndi kukula kwa ma pores, ndipo kupanga kwa chinthucho kumachitika pansi pa kupanikizika kochepa komanso kwapakati.
Njira yopangira thovu la microcellular ikhoza kugawidwa m'magawo atatu:
Choyamba, madzi ofunikira kwambiri (carbon dioxide kapena nayitrogeni) amasungunuka mu guluu wosungunuka wotentha kuti apange yankho la gawo limodzi. Kenako amalowetsedwa m'chibowo cha nkhungu pa kutentha kochepa ndi kupanikizika kudzera mu nozzle yosinthira. Chiwerengero chachikulu cha ma nuclei a mpweya amapangidwa mu chinthucho chifukwa cha kusakhazikika kwa mamolekyu komwe kumachitika chifukwa cha kutentha ndi kuchepa kwa kuthamanga. Ma nuclei a ma bullet awa amakula pang'onopang'ono ndikupanga mabowo ang'onoang'ono.
Zinthu zomwe zimachitika:
(1) Kuumba jakisoni molondola.
(2) Kupyola malire ambiri a kuumba jakisoni wachikhalidwe. Kungachepetse kwambiri kulemera kwa ntchito ndikufupikitsa nthawi youmba.
(3) Kusintha kwa mawonekedwe ndi kukhazikika kwa gawo la ntchitoyo kumawonjezeka kwambiri.
Ntchito:

Kuumba Nkhonya
Kuumba blow molding ndi kuyika zinthu zopangira thermoplastic zosungunuka zomwe zimatulutsidwa kuchokera ku extruder kupita ku nkhungu, kenako n’kupukutira mpweya mu nkhungu. Zinthu zopangira sungunukazo zimakula chifukwa cha mphamvu ya mpweya ndipo zimamatira ku khoma la nkhungu. Pomaliza, njira yoziziritsira ndi kulimbitsa mawonekedwe a chinthu chomwe mukufuna. Kuumba blow molding kumagawidwa m'mitundu iwiri: kupanga blow molding ndi kupanga blow hole.
1) Kujambula Mafilimu
Kupopera filimu ndi kutulutsa pulasitiki wosungunuka mu chubu chopyapyala chozungulira kuchokera pamalo ozungulira a mutu wa chopopera. Nthawi yomweyo, popera mpweya wopanikizika kulowa mkati mwa chubu chopyapyala kuchokera pakati pa mutu wa makina. Chubu chopyapyalacho chimapopera mu filimu yopyapyala yokhala ndi mainchesi akulu (yomwe imadziwika kuti chubu cha thovu), ndipo imapindidwa ikazizira.
2) Kuumba Mphepo Yopanda Chingwe
Kuumba mopanda kanthu ndi ukadaulo wachiwiri woumba womwe umadzaza parison yonga rabara yotsekedwa mu dzenje la nkhungu kukhala chinthu chopanda kanthu pogwiritsa ntchito mpweya. Ndipo ndi njira yopangira zinthu zapulasitiki zopanda kanthu. Kuumba mopanda kanthu kumasiyana malinga ndi njira yopangira parison, kuphatikizapo kupanga mopanda kanthu, kupanga mopanda kanthu, ndi kupanga mopanda kanthu.
1))Kuumba kwa nkhonya yotulutsa:Ndikofunikira kutulutsa chubu cha chubu pogwiritsa ntchito chotulutsira, kuchiyika mu dzenje la nkhungu ndikutseka pansi pamene kuli kotentha. Kenako perekani mpweya wopanikizika mkati mwa chubucho popanda kanthu ndikuchiwombera kuti chikhale chowoneka bwino.
2))Kupaka jakisoni wa nkhonya:Chifaniziro chomwe chimagwiritsidwa ntchito chimapezeka pochiyika jekeseni. Chifanizirocho chimakhalabe pakati pa chifanizirocho. Chifanizirocho chikatsekedwa ndi chifanizirocho, mpweya wopanikizika umadutsa mu chifanizirocho. Chifanizirocho chimadzazidwa ndi mpweya, kuziziritsidwa, ndipo chinthucho chimapezedwa pambuyo pochichotsa.
Ubwino:
Kukhuthala kwa khoma la chinthucho ndi kofanana, kupirira kulemera kwake ndi kochepa, kukonzedwa pambuyo pake ndi kochepa, ndipo ngodya za zinyalala ndi zazing'ono.
Ndi yoyenera kupanga zinthu zazing'ono zoyengedwa bwino zokhala ndi magulu akuluakulu.
3))Kuumba kotambasula:Chigawo chomwe chatenthedwa kufika kutentha kotambasula chimayikidwa mu blow mold. Chogulitsachi chimapezeka potambasula motalikira ndi ndodo yotambasula ndikutambasula mopingasa ndi mpweya wopanikizika wophwanyidwa.
