Uma kuziwa ekudaleni isikhunta esinembile nesisezingeni eliphezulu, uhlobo lweithubhu yesikhuntaesetshenzisiwe idlala indima ebalulekile kumphumela wokugcina. Olunye uhlobo lweshubhu lokukhunta oluthole ukuthandwa eminyakeni yamuva nje ishubhu lesikwele lesikhunta, ikakhulukazi i-I-CuAg isikhunta amashubhu. Lawa mashubhu anikeza uhla lwezinzuzo futhi asetshenziswa kabanzi ezimbonini ezahlukahlukene ngenxa yokuguquguquka nokuqina kwawo.

Amashubhu esikhunta esiyisikwele, obeye aziwe njengoamashubhu isikhunta, zenzelwe ukuhlinzeka ngesimo esizinzile nesifanayo sesikhunta abasidalayo. Lokhu kubaluleke kakhulu ezimbonini ezifana nokwenza ubucwebe, lapho ukunemba kuyisihluthulelo. Ukuma kwesikwele kwala mashubhu kuvumela isikhunta esingaguquki, okuholela emikhiqizweni eqediwe ephezulu.

Amashubhu esikhunta e-CuAg, enziwe ngokukhethekile ngama-alloys ethusi nawesiliva, aziwa ngokuhambisa kwawo okushisayo okuhle kakhulu kanye nokumelana nokugqwala. Lokhu kubenza balungele ukusetshenziswa ekukhiqizeni isikhunta esiyinkimbinkimbi nesinemininingwane. Inhlanganisela yethusi nesiliva iphinde inikeze isiphetho esibushelelezi, okubalulekile ekudaleni isikhunta esingenasici.

Enye yezinzuzo ezibalulekile zokusebenzisa amashubhu esikhunta esiyisikwele, ikakhulukazi amashubhu esikhunta se-CuAg, amandla awo okumelana namazinga okushisa aphezulu. Lokhu kubaluleke kakhulu ezinqubweni ezifana nokuphonsa kwensimbi, lapho amashubhu esikhunta evezwa ukushisa okukhulu. Ukuqina kwalawa mashubhu kuqinisekisa ukuthi angakwazi ukugcina isimo nobuqotho bawo ngisho nangaphansi kokushisa okukhulu, okuholela ekubunjeni okungaguquki nokuthembekile.

Ngaphezu kwalokho, ukuguquguquka kwamashubhu okubunjwa kwesikwele kudlulela ekusebenzisaneni kwawo nezinto zokubumba ezahlukahlukene. Noma ngabe i-wax, i-resin, noma insimbi, lawa mashubhu angakwazi ukumumatha inhlobonhlobo yezinto, awenze afanelekele izinhlelo zokusebenza ezihlukahlukene.

Sengiphetha, amashubhu esikhunta esiyisikwele, ikakhulukazi amashubhu esikhunta se-CuAg, anikeza inhlanganisela yokunemba, ukuqina, nokuguquguquka okuwenza abe ithuluzi elibalulekile ezinqubweni zokwenza isikhunta. Ikhono lazo lokumelana namazinga okushisa aphakeme kanye nokufaka izinto zokubumba ezihlukene lizenza impahla ebalulekile ezimbonini ezidinga isikhunta esicophelelayo nesisezingeni eliphezulu. Njengoba ubuchwepheshe buqhubeka nokuthuthuka, isidingo sezixazululo ezintsha ze-mold mold tubes ezifana ne-CuAg mold tubes kulindeleke ukuthi sikhule, siqinise indawo yazo endaweni yokukhiqiza nokukhiqiza.
