Isitofu sokungunda sisixhobo sokuvelisa iimveliso zeplastiki;Kwakhona sisixhobo sokunika iimveliso zeplastiki isakhiwo esipheleleyo kunye nemilinganiselo echanekileyo.I-injection molding yindlela yokucubungula esetyenziswa kwimveliso yobuninzi yamalungu athile anzima.Ngokukodwa, iplastiki eshushu inyibilikayo ifakwe kwi-mold cavity ngumatshini wokubumba umjovo phantsi koxinzelelo oluphezulu, kwaye imveliso eyenziweyo ifunyenwe emva kokupholisa kunye nokunyanga.
Isitofu sokungunda sinokwahlulwa sibe ngundo lweplastiki ye-thermosetting kunye nokungunda kweplastiki ye-thermoplastic ngokweempawu zokubumba;Ngokwenkqubo yokubumba, inokohlulwa ibe ngundo lokutshintshela, ukuvuthela ukubumba, ukubumba ukubumba, ukubumba i-thermoforming, i-mold yokucinezela eshushu (i-compression mold), i-injection mold, njl. kunye nohlobo olungaphuphumanga kwindlela yokuphuphuma, kunye nenaliti yokubumba inokwahlulwa ibe ngundo lwembaleki ebandayo kunye nokungunda kwembaleki eshushu ngendlela yenkqubo yokugawula;Ngokwendlela yokulayisha kunye nokukhupha, inokwahlulwa ibe yintlobo yeselula kunye nohlobo olusisigxina.
Nangona ulwakhiwo lokubumba lunokwahluka ngenxa yeendidi kunye nokusebenza kweeplastiki, imilo kunye nesakhiwo seemveliso zeplastiki kunye nohlobo lomatshini wokutofa, isakhiwo esisisiseko siyafana.Umngundo ubukhulu becala wenziwe ngenkqubo yokungena, inkqubo yokulawula ubushushu, iinxalenye zokwenza iinxalenye kunye nezakhiwo.Phakathi kwazo, inkqubo yokungena kunye neengxenye zokubumba ngamalungu adibanisa ngokuthe ngqo kunye neeplastiki kunye nokutshintsha ngeeplastiki kunye neemveliso.Zizona nxalenye zinzima kwaye zitshintsha kwi-mold yeplastiki, ezifuna ukugqitywa komatshini kunye nokuchaneka.
I-injection mold iquka i-mold ehambayo kunye ne-mold fixed.I-mold ehambayo ifakwe kwi-template ehambayo yomshini wokubumba i-injection, kwaye i-mold fixed ifakwe kwi-template echanekileyo yomshini wokubumba umjovo.Ngexesha lokubunjwa kwenaliti, i-mold ehambayo kunye ne-mold fixed ivaliwe ukwenza inkqubo yokungena kunye ne-cavity.Xa uvula i-mold, i-mold ehambayo kunye ne-mold fixed iyahlukana ukukhupha iimveliso zeplastiki.Ukuze kuncitshiswe umsebenzi onzima woyilo lokungunda kunye nokuveliswa, uninzi lwezitofu zokubumba zisebenzisa iziseko zokungunda eziqhelekileyo.
