Ukuseta umatshini wokubumba isitofu kubandakanya iiparamitha ezininzi, undoqo kukuseta ubushushu obufanelekileyo beplastizing (umzekelo, iqondo lobushushu lomphanda ngokuqhelekileyo lingama-200-300 isidanga), uxinzelelo lwenaliti kunye nesantya (uxinzelelo lwe-50-150MPa, isantya se-30-90mm/s), kunye nobushushu bokungunda kunye nexesha lokupholisa (ubushushu bokubumba bungama-20-80 isidanga, ubukhulu bemveliso kunye nexesha lokupholisa). Ezi parameters kufuneka zihlengahlengiswe ngokweempawu eziphathekayo kunye neemfuno zemveliso ukufezekisa iziphumo ezilungileyo zokubumba. Ngelixa singaboneleli ngoomatshini bokubumba inaliti, sinikezela ngokufuduswa kwefektri yobuchwephesha kunye neenkonzo zokuphatha izixhobo, kubandakanya ukufakwa kunye nokugunyaziswa kwezixhobo ezinkulu ezinje ngoomatshini bokubumba inaliti. Sineqela lolwakhiwo oluqeqeshwe ngokugqibeleleyo ukuqinisekisa ukubekwa kwezixhobo ezichanekileyo kunye novavanyo lokusebenza.
Intshayelelo kumatshini wokubumba inaliti kufuneka iqale ngemiba emine: ukusebenza okusisiseko, imigaqo yokhuseleko, izixhobo kunye nokuqonda komngundo, kunye noseto lweparamitha yenkqubo, ngakumbi ngolu hlobo lulandelayo:
- Umsebenzi oSisiseko: Ziqhelanise neemowudi zemanuwali,-ezizenzekelayo, kunye nezenzekela ngokupheleleyo, kwaye ube nobuchule kwiindlela zokuqalisa, zokumisa, kunye nokulungelelanisa iiparamitha, ezinje ngogcino lwemathiriyeli, inaliti, kunye noseto lobushushu.
- Izikhokelo zoKhuseleko: Ukuthobela ngokuthe ngqo kwiinkqubo zokusebenza, nxiba izixhobo zokukhusela, kwaye uziqhelanise nendawo yeqhosha lokumisa ungxamiseko ukuze ugweme ukulimala komatshini okanye ukutshiswa kwamaqondo aphezulu.
- Izixhobo kunye nokuqonda kwe-Mold: Qonda isakhiwo kunye nomgaqo wokusebenza kumatshini wokubumba umjovo, ukufakwa kwe-master mold kunye neendlela zokulungisa, kwaye uqinisekise ukuba i-mold kunye ne-nozzle ihambelana.
- Izicwangciso zeParameter yeNkqubo: Funda malunga neempawu eziphathekayo kwaye usete iiparitha eziphambili ezifana noxinzelelo lwenaliti, isantya, ixesha lokubamba, kunye nexesha lokupholisa ngokwezinto eziphathekayo kunye neemfuno zemveliso.
- Intshayelelo koomatshini bokuBumba bokuTofwa: Sincoma ukuqala ngokufuduswa kwezixhobo kunye nokulungiswa kweempazamo. Ngelixa singathengisi oomatshini bokubumba inaliti, sineminyaka eyi-18 yamava ekufuduseni izixhobo ezinkulu kwaye sinokubonelela ngofakelo lomatshini wokubumba inaliti kunye neenkonzo zokubeka indawo. Kumsebenzi wokwenyani, kubalulekile ukulawula ubushushu bomphanda (ulawulo lomphanda kwi-3-imimandla emi-5) kunye noseto lwegophe loxinzelelo. Iiparamitha eziqhelekileyo zoomatshini bokubumba esiye sabasa kwenye indawo ziquka: isantya se-screw 50-120 rpm, kunye nesantya sokutofa esilawulwa kumacandelo amathathu (slow-fast-slow).
