Izinqubo ezahlukahlukene zokulingisa ziye zathuthukiswa ngokuhamba kwesikhathi ngabasunguli nabacwaningi, ngayinye inezici zayo kanye nokusetshenziswa kweizinsimbi zensimbiukuhlangabezana nezidingo ezithile zobunjiniyela nesevisi. Ngokuvamile, ngokuya ngokuthi ukubunjwa kokubunjwa kungasetshenziswa kabusha noma cha, izinqubo zokuphonsa zingahlukaniswa zibe Expendable Mold Casting, Permanent Mold Casting kanye ne-Composite Mold Casting. I-mold casting casting nayo ingahlukaniswa ibeukuphonsa isihlabathi, ukubunjwa kwegobolondo,ukutshala imalikanye nokukhishwa kwegwebu elilahlekile, kuyilapho ukubunjwa kwesikhunta okuhlala njalo kuhlanganisa amandla adonsela phansi, ukucindezela okuphansi kwe-die cast kanye nokucindezela okuphezulu kwe-die cast.
1. Expendable Mold Casting
Izibunjwa ezisebenzisekayo ngokuvamile zenziwe ngesihlabathi, ukhonkolo, ubumba, nezinye izinto ezifanayo. Ngokuvamile kuhlanganiswe nama-binder ahlukahlukene, noma ama-bonding agents. Isikhunta sesihlabathi esijwayelekile siqukethe u-90% wesihlabathi, u-7% wobumba, no-3% wamanzi. Lezi zinto ziyaphikisana (zimelana nokushisa okuphezulu kwensimbi encibilikisiwe). Ngemuva kokuthi ukubunjwa sekuqinile, isikhunta esisebenzisekayo kulezi zinqubo siyaphulwa ukuze kukhishwe ukukhishwa kwensimbi kokugcina.
2. Permanent Mold Casting
Isikhunta esihlala njalo senziwe ikakhulukazi ngezinsimbi ezigcina amandla emazingeni okushisa aphezulu. Zisetshenziswa ngokuphindaphindiwe. Idizayinelwe ukuze izinsimbi zensimbi zisuswe kalula futhi isikhunta singasetshenziswa futhi. Ukubunjwa kwesikhunta unomphela kusebenzisa i-conductor yokushisa engcono kunesikhunta esinganwebekayo se-nonmetallic; ngakho-ke, ukubunjwa kokuqinisa kungaphansi kwezinga eliphezulu lokupholisa, elithinta i-microstructure kanye nosayizi wokusanhlamvu.
3. Ukubunjwa Kwesikhunta Esihlanganisiwe
Izibunjwa ezihlanganisiwe zenziwe ngezinto ezimbili noma ngaphezulu ezihlukene (njengesihlabathi, i-graphite, nensimbi) kuhlanganisa izinzuzo zento ngayinye. Izibunzi eziyinhlanganisela zinengxenye ehlala njalo futhi esebenzisekayo futhi zisetshenziswa ezinqubweni ezihlukahlukene zokubunjwa ukuze kuthuthukiswe amandla esikhunta, ukulawula amazinga okupholisa, nokwandisa umnotho jikelele wenqubo yokuphonsa.
