Kuti apange nkhungu zokhala ndi mipanda yopyapyala bwino, madzi amadzimadzi a zida zomangira jekeseni wokhala ndi mipanda yopyapyala ayenera kukhala abwino, ndipo ayenera kukhala ndi chiŵerengero chachikulu choyenda mpaka kutalika.Ilinso ndi mphamvu zoyambukira kwambiri, kutentha kwakukulu kosokoneza, komanso kukhazikika kwabwino.Kuphatikiza apo, kukana kutentha, kuchepa kwamoto, kusonkhana kwamakina ndi mawonekedwe azinthu ziyenera kufufuzidwanso.Tiyeni tiyang'ane pa maziko ongoyerekeza a kupanga nkhungu zokhala ndi mipanda yopyapyala.
Pakalipano, zipangizo zomwe zimagwiritsidwa ntchito kwambiri popanga jekeseni zimaphatikizapo polypropylene PP, polyethylene PE, polycarbonate (PC), acrylonitrile-butadiene-styrene (ABS) ndi PC / ABS blends.Njira yodzaza ndi kuzizira kwa jekeseni wamba mu nkhungu zimalumikizana.Pamene polima kusungunuka umayenda, kutsogolo kusungunula kumakumana pachimake pamwamba kapena pakhoma khoma ndi kutentha ndi otsika, ndipo wosanjikiza adzapangidwa pamwamba Chosanjikiza condensation, kusungunuka kumapitiriza kuyenda patsogolo mu condensation wosanjikiza, ndi makulidwe a wosanjikiza condensation zimakhudza kwambiri otaya polima.
Kufufuza mozama komanso mozama kumafunika pa chikhalidwe cha condensation wosanjikiza mu jekeseni woonda-khoma.Chifukwa chake, ntchito yambiri ikuyenera kuchitidwa pakuyerekeza kwa manambala a jekeseni wa mipanda yopyapyala.Mfundo yoyamba ndikufufuza mozama komanso mozama za chiphunzitso cha jekeseni wopyapyala wa khoma, makamaka katundu wa condensation wosanjikiza, kuti apereke malingaliro omveka bwino ndi malire.Kuchokera pazomwe tafotokozazi, zikuwoneka kuti popanga jekeseni wowonda-khoma, mikhalidwe yambiri imakhala yosiyana kwambiri ndi ya jekeseni wamba.
Mukayerekezera, malingaliro ambiri ndi malire amtundu wa masamu a melt flow amayenera kusinthidwa bwino pakuumba jekeseni wocheperako.
