Okwesibili, lapho kusebenza umhlangano wombuso, ngoba ipulasitiki iqukethe i-chlorine ne-fluoride nezinye izinto, amanye amagesi aqinile anqunywe ngemuva kokufudumeza, akhulise ubulukhuni bayo, futhi kwandisa umphumela wokugaya. Ngakho-ke, imibungu yokubumba kufanele ibe nokuphikiswa kokugqwala.
UBorld Mold Umbungu udlala indima ebalulekile ekukhiqizweni kwesikhunta. Ubulukhuni bungenye yezimo ezidingekayo zemibungu yokubumba isikhunta. Ubulukhuni buyinto ebalulekile ethinta ukumelana nokugqoka. Ngokuvamile ukukhuluma, kuphakama ubulukhuni bengxenye yokubumba, okuncane ukugqokwa, okungcono ukumelana nokugqokwa.
Lapho izinga lokushisa likhuphukela ekamelweni lokushisa, kufanele lehliswe ngesikhathi ukuze kuqhutshekwe nokuqeda ingcindezi yokwelashwa okubandayo, kugwenywe ukwenza imifantu yokwelapha okubandayo, ukuthola izicubu ezizinzile nokusebenza, nokuqinisekisa ukuthi isisekelo sesikhunta esinembayo asigogeki ngesikhathi sokugcinwa nokusetshenziswa.
Isisekelo sesikhunta siwumkhiqizo osuphelile wesikhunta, owakhiwa izesekeli zamapuleti ensimbi ahlukahlukene. Kungashiwo ukuthi iwuhlaka lwamathambo esikhunta sonke.
Ngenxa yokuthi izisekelo zesikhunta ezihlukene ze-die-casting zinezakhiwo ezihlukene ezicini ezihlukahlukene, ukusetshenziswa kwazo kuhlukile.
I-"non-standard" egameni lesisekelo sesikhunta esingajwayelekile sisho okungezona okujwayelekile, futhi lokhu okungajwayelekile kubonakaliswa ezicini eziningi zesisekelo sesikhunta.
