jekeseni nkhungundi zida zazikulu zopangira mafakitale, kugwiritsa ntchito nkhungu kupanga mbali zapulasitiki, zokhala ndi zabwino zingapo monga kupereka magwiridwe antchito, zosavuta kuonetsetsa kuti zili bwino, zotsika mtengo zopangira, jekeseni wa jekeseni amagwiritsidwa ntchito kwambiri popanga mafakitale.Monga njira yofunika kwambiri yopangira jekeseni, mtundu wa nkhungu zake umakhudza mwachindunji ubwino wa mankhwala, pamene mtengo wa nkhungu umakhala ndi gawo lalikulu la mtengo wa chitukuko cha mabizinesi.Chifukwa chake sinthani moyo wautumiki / moyo wowomberedwa wa nkhungu za jakisoni kuti muchepetse mtengo wazinthu zamapulasitiki, kupititsa patsogolo zokolola zamabizinesi komanso kupikisana kumakhudza kwambiri.
pulasitiki jekeseni akamaumba ndondomeko makamaka pulasitiki zopangira mu jekeseni makina mbiya pambuyo Kutentha plasticization, mu jekeseni makina wononga propulsion, pambuyo pulasitiki kufika kutentha kwina, ndi kuthamanga kwina ndi liwiro mwa jekeseni makina nozzle mu nkhungu patsekeke, ndi ndiye nkhungu pambuyo kuthamanga, mankhwala kuzirala ndi kutsegula nkhungu ndi kutenga mbali pulasitiki.
Panthawi yopangira jekeseni, pamwamba pa nkhungu iyenera kupirira kupanikizika pamene nkhungu imatsekedwa, kupanikizika kwa pulasitiki kusungunuka mu nkhungu ndi mphamvu yokoka pamene nkhungu imatsegulidwa, yomwe mphamvu ya pulasitiki imasungunuka. pa mphanga ndi chofunika kwambiri.Pa nthawi yomweyo, nkhungu ayenera anakhalabe pa zinthu zina kutentha, nkhungu kutentha yesetsani kukwaniritsa kusintha cyclical, kasitomala amafuna nkhungu kutentha ayenera kukhala mkulu, amene angathe kuchepetsa Kutha kwa kufufuza, ndi mbali pulasitiki pa nkhungu kutentha. ayenera kukhala otsika.Apo ayi mankhwala deformation adzakhala ndi lalikulu.Pansi pazimenezi zogwirira ntchito, nkhungu imatha kusinthika kwambiri komanso kutopa kotentha ndi kuzizira, makamaka chifukwa cha kutentha ndi kupanikizika.
Pulasitiki m'kati kudzaza nkhungu patsekeke, nkhungu kupanga mbali ndi kutentha ndi mkulu kuthamanga Sungunulani scouring, otaya kukangana, mu ndondomeko ya mankhwala demoulding, patsekeke ndi pachimake ndi mbali pulasitiki ntchito ndondomeko n'zosavuta kutulutsa mikangano, chifukwa. mu zochitika za nkhungu kuvala.Panthawi imodzimodziyo, chifukwa cha kutsegula ndi kutseka pafupipafupi kwa nkhungu, zigawo zowongolera nkhungu ndi zigawo zoumba zimakhala zosavuta kuvala ndi kung'ambika zomwe zimapangitsa kuti zisungunuke.
Poumba, mapulasitiki ena amawola pansi pa kutentha kwakukulu ndi kukakamizidwa kuti apange mpweya wowononga, womwe ukhoza kuwononga mosavuta ndikuwononga pamwamba pa nkhungu, kuwononga pamwamba pa nkhungu.
Pamene kupanga jekeseni nkhungu kufika pa nambala inayake, pamwamba khalidwe la mankhwala chifukwa cha kuvala mopitirira muyeso wa nkhungu sangathe kufika zofunika, mankhwala kusefukira ndi kuuluka m'mphepete ndi lalikulu, ndipo nkhungu patsekeke ndi pachimake sangathe kukonzedwa, moyo wa nkhungu umatha.Chiwerengero chonse cha zigawo za pulasitiki zomwe zinatsirizidwa nkhungu isanathe imadziwikanso kuti moyo wa nkhungu.
