Ukuqonda oomatshini bokucwangcisa kwishishini lokupakisha ngentsimbi

--- Oomatshini bokucwangcisa zizixhobo ezibalulekileyo kumzi-mveliso wokupakisha kunye nokushicilela, ingakumbi xa usebenza ngezixhobo zokupakisha ngesinyithi njenge-aluminium kunye ne-aluminium alloys. Ezi matshini zenzelwe ukuphucula ukuchaneka kunye nokusebenza kwemisebenzi, ukwenza ukuba zibalulekile kwiinkqubo ezahlukeneyo zemveliso. Kwimeko yokupakisha ngesinyithi, oomatshini bokusika basetyenziselwa ukususa
