Kukho iindlela ezininzi zokwahlula iimbumba zeplastiki, kwaye zinokwahlulwa zibe zezi ndidi zilandelayo ngokweendlela ezahlukeneyo zokwenza kunye nokusebenza kwamalungu eplastiki:
Isitofu sokungunda sikwabizwa ngokuba ngumngundo wokutofa.Inkqubo yokubumba yale mold ibonakaliswe ngokubeka izinto eziluhlaza zeplastiki kwi-barrel yokufudumala yomshini wokutofa.Iplastiki iyafudunyezwa kwaye inyibilike, kwaye iqhutywa sisikrufu okanye i-plunger yomatshini wokutofa, ingena kumngxuma wokungunda nge-nozzle kunye nenkqubo yokugalela i-mold, kwaye iplastiki yenziwa kwindawo yokubumba ngokugcina ubushushu, ukubamba uxinzelelo, kwaye Ukupholisa.Ngenxa yokuba isixhobo sokufudumeza kunye nokucinezela sinokusebenza ngokwezigaba, ukubumba inaliti akunakubumba kuphela iinxalenye zeplastiki ezinemilo entsonkothileyo, kodwa zikwanemveliso ephezulu kunye nomgangatho olungileyo.Ke ngoko, ii-akhawunti zokubumba iinaliti zithatha indawo enkulu ekubunjweni kwamalungu eplastiki, kwaye iinaliti zokubumba zibalelwa ngaphezulu kwesiqingatha sezinto zokubumba zeplastiki.Umatshini wokutofa usetyenziselwa ukubumba i-thermoplastics.Kwiminyaka yakutshanje, sele isetyenziselwe ngokuthe ngcembe ukubumba iiplastiki ze-thermosetting.
I-compression mold ikwabizwa ngokuba yi-compression mold okanye i-rubber mold.Inkqubo yokubumba impawu yolu bumba kukuba izinto eziluhlaza zeplastiki zongezwa ngokuthe ngqo kwindawo evulekileyo yokubumba, kwaye i-mold ivaliwe.Emva kokuba iplastiki ikwimeko etyhidiweyo phantsi kwesenzo sobushushu kunye noxinzelelo, i-cavity igcwele uxinzelelo oluthile.Ngeli xesha, i-molecular structure yeplastiki yavelisa i-chemical crosslinking reaction, eyaye yaqina ngokuthe ngcembe kwaye yabeka.Iimolds zoxinzelelo zisetyenziswa kakhulu kwiiplastiki ze-thermosetting, kwaye iindawo zeplastiki ezibunjiweyo zisetyenziswa kakhulu kwizindlu zokutshintsha kombane kunye neemfuno zemihla ngemihla.
Ugqithiso lokungunda lukwabizwa ngokuba yinaliti yokungunda okanye i-extrusion mold.Inkqubo yokubumba yale mold ibonakaliswe kwinto yokuba izinto eziluhlaza zeplastiki zongezwa kwigumbi lokutyisa elifudumalayo, kwaye ke uxinzelelo lusetyenziswa kwiplastiki yempahla ekrwada kwigumbi lokutyisa ngekholamu yoxinzelelo.Iplastiki iyancibilika phantsi kobushushu obuphezulu kunye noxinzelelo kwaye ingene kwi-cavity ngokusebenzisa inkqubo yokugalela i-mold.Ukudityaniswa kwemichiza kwenzeka kwaye ngokuthe ngcembe kuyaqina.Inkqubo yokubumba yokudluliselwa isetyenziswa kakhulu kwiiplastiki ze-thermosetting, ezinokuthi zenze iindawo zeplastiki ezinzima ngakumbi.
I-Extrusion die ikwabizwa ngokuba yi-extruder head.Lo mngundo unokuqhubeka uvelisa iiplastiki ezinemilo enqamlezileyo efanayo, njengemibhobho yeplastiki, iirodi kunye namaphepha.Isixhobo se-extruder sokufudumeza kunye nokucofa siyafana neso somatshini wokutofa.Iplastiki etyhidiweyo idlula kwintloko yomatshini ukuze yenze inxalenye yeplastiki ebunjiweyo eqhubekayo, enemveliso ephezulu kakhulu.
