Lingaliro la nkhungu ndi kuumba ndilodziwika kwambiri m'mafakitale apulasitiki.Pulasitiki ili ndi zinthu zabwino monga kusungunuka kwambiri, kutsika mtengo, kukhazikika kwakukulu.Choncho amagwiritsidwa ntchito ponseponse pakuumba.Kwenikweni Kuumba jekeseni wa Plastiki ndiye njira yayikulu yopangira zida zapulasitiki.Kubwera ku lingaliro la kuumba, ndi njira yopangira yomwe zinthu zamadzimadzi kapena pliable zatsopano zimapeza mawonekedwe olimba otchedwa nkhungu.Mwachidule, kuumba pulasitiki ndi njira yomwe pulasitiki imapangidwira mu mawonekedwe omwe akufuna.
Kuumba jekeseni kumathandiza kwambiri popanga zinthu zambiri zapakhomo ndi zamakampani.Amagwiritsidwa ntchito popanga zida zamitundu yambiri monga nyumba zamagetsi, zotengera, zisoti zamabotolo, zamkati zamagalimoto, zisa, ndi zinthu zina zambiri zamapulasitiki zomwe zilipo masiku ano.Zomwe zili ngati kulekerera kwakukulu, kubwereza, kusankha kwakukulu kwazinthu, mtengo wotsika wantchito, kutayika kochepa kwambiri, komanso kufunikira kochepa komaliza zigawo mutatha kuumba ndizo zabwino zazikulu za jekeseni.
The pulasitiki jakisoni nkhungu nthawi zambiri amafuna zotsatirazi popanga jekeseni pulasitiki akamaumba-
1. makina opangira jekeseni2.pulasitiki yaiwisi 3.nkhungu.
Popanga jakisoni wapulasitiki, pali mitundu ingapo ya zinthu zopangira monga pulasitiki ya thermosetting, ma elastomers ndi ma polima a thermoplastic (resin) ndi zina zomwe zimagwiritsidwa ntchito popanga jakisoni wapulasitiki chifukwa zidazi zimakhala ndi kukhuthala kwakukulu.Makina ojambulira pulasitiki ali ndi zigawo zikuluzikulu monga hopper yakuthupi, gawo lotenthetsera, plunger etc. Pulasitiki imasungunuka mu makina opangira jekeseni ndiyeno imalowetsedwa mu nkhungu, kumene imazizira ndikukhazikika mu gawo lomaliza.
