Umqondo wokubumba nokubumba uthandwa kakhulu ezimbonini zepulasitiki.Ipulastiki inezici ezinenzuzo ezifana nokuguquguquka okuphezulu, izindleko ezishibhile, ukuzinza okuphezulu.Ngakho-ke isetshenziswa kabanzi ekubumbeni.Ngokuyisisekelo ukubumba komjovo wePlastiki kuyinqubo eyinhloko yokukhiqiza izingxenye zepulasitiki.Uma sifika emcabangweni wokubumba, kuyinqubo yokukhiqiza lapho izinto ezintsha eziwuketshezi noma eziphephekayo zithola ukuma okuqinile okubizwa ngokuthi isikhunta.Ngamagama alula, ukubumba kwepulasitiki kuyinqubo lapho ipulasitiki ibunjwa ibe yisimo esifunwayo.
Ukubumba umjovo kunegalelo elikhulu ekukhiqizeni imikhiqizo eminingi yasekhaya neyezimboni.Isetshenziselwa ukwakha izinhlobo eziningi zezinto zokusebenza njengezindlu zikagesi, iziqukathi, izikepisi zamabhodlela, izinto zangaphakathi zezimoto, amakamu, neminye imikhiqizo eminingi yepulasitiki etholakala namuhla.Izici ezifana nokunemba okuphezulu kokubekezelelana, ukuphindaphinda, ukukhethwa kwezinto ezinkulu, izindleko eziphansi zabasebenzi, ukulahlekelwa okuncane kwe-scrap, nesidingo esincane sokuqeda izingxenye ngemva kokubumba yizinzuzo ezinkulu zokubumba umjovo.
Isikhunta somjovo wepulasitiki ngokuvamile sidinga ukulandela lapho kwakhiwa umjovo wepulasitiki-
1. umshini wokubumba umjovo2.impahla yepulasitiki eluhlaza3.Isikhunta.
Ukuze kwenziwe imijovo yepulasitiki, kunezinhlobo ezahlukahlukene zezinto ezingavuthiwe ezifana nepulasitiki ye-thermosetting, ama-elastomers nama-polymers we-thermoplastic (ama-resins) njll asetshenziselwa ukwenziwa kwemijovo yepulasitiki njengoba lezi zinto zine-viscosity enkulu.Imishini yokujova yepulasitiki inezingxenye eziyisisekelo ezifana ne-material hopper, iyunithi yokufudumeza, i-plunger njll. Ipulasitiki iyancibilika emshinini wokubumba umjovo bese ijova esikhunjeni, lapho ipholisa futhi iqina engxenyeni yokugcina.
