Abathengi abaninzi bathenga ifanitshala yangaphandle, ejongene neetafile zamaplanga kunye nezihlalo kunye neetafile ze-aluminium alloy kunye nezitulo, abayi kunqikaza ukukhetha iitafile kunye nezihlalo ze-aluminium eziphosiweyo, abathengi ababonakalayo baye baqaphela ngokuthe ngcembe iitafile ze-aluminium kunye nezihlalo eziphezulu ezisemgangathweni zithembekile. Kodwa ebusweni beentlobo ezininzi zeetafile ze-aluminium kunye nezihlalo kunye nabavelisi bazo kwiimarike, abaninzi abathengi basajongene nobunzima obuninzi xa bekhetha. Le ngxaki ingasombululwa ngokwembono yemveliso ngokwayo kunye nomenzi.
Okokuqala, gweba ngokwembono yemveliso
I-Cast{0}}iitafile ze-aluminiyam kunye nezitulo zenziwe nge-aluminiyam ecocekileyo kunye ne-alloyi ye-aluminiyam ngokomlinganiselo we-die{1}}inkqubo yokuphosa, ifudunyezwe kwimeko etyhidiweyo kunye nokupholisa ukungunda kunye nokugqibezela uyilo. Umgangatho olungileyo uphose iitafile kunye nezihlalo ze-aluminiyam, inkangeleko yesakhiwo esipheleleyo yindawo edibeneyo, akukho nto icacileyo ye-welding; Xa ubamba itafile kunye nesitulo, unokuva ukuguda kunye nokuqina kwentsimbi. Xa uphakamisa itafile kunye nesihlalo kwaye ushukumise, awukwazi ukuva nasiphi na isandi sangaphandle, kwaye ngokucacileyo unokuziva ukuba isitulo sine "sense of reality". Abona bahluphekayo{5}}iitafile kunye nezitulo zealuminiyam zixutywa nesanti, ilitye kunye nezinye iimagazini, ezivelisa ingxolo efihlakeleyo xa zishukunyiswa.
Okwesibini, gweba ngokwembono yomenzi
Abavelisi abalungileyo beemveliso zendalo bangcono, kwaye bagwebe ukuba zeziphi iitafile kunye nezitulo ze-aluminiyam ezigqithisekileyo, ngokukodwa ukubona imveliso yayo, izixhobo zokuvavanya, ukubeka iliso kwishishini kunye nezinye izatifikethi zigqityiwe. Abavelisi beengcali abanalo kuphela iimfuno ezingqongqo kumgangatho wemveliso, kodwa bahlawula ingqalelo enkulu kumava omthengi. Nokuba abathengi bakhangela kwiwebhusayithi esemthethweni okanye ngeqela lesithathu okanye ezinye iindlela zokuthengisa, banokufumana ulwazi oluthe kratya, kwaye isidima sabo kunye namava omsebenzisi axatyiswe kakhulu. Xa abathengi benomdla kwiimveliso okanye benemibuzo efanelekileyo, abasebenzi babo benkonzo yabathengi baya kunika abathengi iimpendulo ngomonde, kwaye abavelisi bazimisele kubathengi kwindawo yokutyelela amava.
Xa ukhetha iitafile kunye nezihlalo ze-aluminium eziphosiweyo, abathengi badla ngokuqwalasela ngakumbi ixabiso. Kwaye ixabiso likwayinto ebalulekileyo echaphazela umgangatho weetafile kunye nezitulo. Amaxabiso eetafile kunye nezitulo ezinomgangatho olungileyo okanye iimpawu ziphezulu kakhulu, zifuna ukuba abathengi benze amalungiselelo ngokwezicwangciso zabo zenkcitho ethile kulo mba.
