Kukho iintlobo ezininzi zokusaswa, ngoko ke umatshini wokuqhumisa wahlukile. Le ilandelayo yimigaqo jikelele yokukhetha umatshini wokuqhushumba odubulayo wokusasa:
1. Iimpawu ze-castings (ubungakanani, umgangatho, imilo kunye nezinto eziphathekayo, njl. njl.) Ubungakanani bebhetshi yokuvelisa, uhlobo lwe-castings kunye neemfuno zokusetyenziswa zisisiseko esibalulekileyo sokukhetha umatshini wokudubula;
2. Ukumiselwa komatshini wokuqhumisa kuya kuqwalaselwa kunye nenkqubo yokuvelisa ngaphambi kokucoca. Umphezulu we-castings uya kucocwa emva kokuqhushumba kwesanti kangangoko kunokwenzeka ukudala iimeko ezifanelekileyo zokucoca. Xa ukudubula ukudubula kunye nenkqubo yokususa isanti yamkelwe, kwimveliso ye-batch, ukususwa kwesanti kunye nokucoca indawo kufuneka kuhlulwe kwiinkqubo ezimbini, eziqhutyelwa kwiisethi ezimbini zezixhobo;
3. Ukususwa kwesanti ye-Electro-hydraulic sand kungasetyenziselwa ukuchithwa kwe-investment kunye nokususwa kwesanti enzima kunye ne-castings ene-complex yangaphakathi kunye nokususwa kwengundoqo okunzima; Ukuphoswa okunomgodi wangaphakathi obunzima kunye nomncinci kunye neemfuno zokucoceka okuphezulu, njengamacandelo e-hydraulic kunye ne-valve castings, ukucocwa kwe-electrochemical kulungele ukusetyenziswa;
4. Kwiintlobo ezininzi kunye nezihlandlo zokuvelisa iibhetshi ezincinci, izixhobo zokucoca okanye iintlobo ezimbini zezixhobo zokuthwala ezinokuguquguquka okuqinileyo kwisayizi yokuphosa kufuneka zikhethwe; Ngezihlandlo zemveliso ezineentlobo ezimbalwa kunye nezixa ezikhulu, izixhobo ezisebenzayo okanye ezikhethekileyo zokuqhushumba kufuneka zikhethwe;
Xa zombini ukucoca okomileyo kunye nokucoca okumanzi kunokuhlangabezana neemfuno zokucoca, kuqala kufuneka kunikwe ukucoca okomileyo okungavelisi ukungcola; Xa ukucoca okomileyo, umatshini oqhumayo odubulayo kunye nokusebenza okuphezulu kunye nokusetyenziswa kwamandla aphantsi kufuneka kuthathelwe ingqalelo kuqala. Ukufakwa kwezinto ezinomphezulu onzima kunye nomgodi, uhlobo lwe-squirrel-cage, uhlobo lwe-manipulator kunye nohlobo lwe-hook ukudubula oomatshini abaqhumayo abanokuthi bajike okanye bahambe ngexesha lokucoca banokukhethwa ngokobukhulu kunye nebhetshi yokuvelisa i-castings.
