1.Kusankha zinthu
Ndalama zasiliva nthawi zambiri zimagwiritsa ntchito siliva weniweni wokhala ndi chiyero cha 999, ndipo fineness ya 925 ndi 900 ndi yomwe imagwiritsidwa ntchito kwambiri padziko lonse lapansi. Ndalama zagolide nthawi zambiri zimapangidwa ndi golide ndi siliva kapena zitsulo zamkuwa zagolide monga 999999 ndi 22K. Golide ndi siliva onse amayengedwa ndikukonzedwa ndi timbewu ta timbewu ta timbewu tating'onoting'ono kudzera pakuyenga ma electrolytic, ndikuwunikidwa kukhala madontho ndi zida zamakono. Zotsatira zakuwunika zikuyimira milingo yovomerezeka komanso kupita patsogolo kwaukadaulo kwadziko.
2. Sungunulani mbale yopindika
Kuchokera ku ng'anjo yamagetsi, chitsulo chosungunula chimaponyedwa muzinthu zosiyanasiyana zamakina kudzera pamakina osalekeza, ndiyeno pamwamba pake amapangidwa ndi makina kuti achotse zonyansa, kenako kuzizira kumakulungidwa pansi pa zofunikira kwambiri zachilengedwe. Pamphero yapadera yomaliza, galasi lowala kwambiri lokhala ndi kulolerana kochepa kwambiri limakulungidwa, ndipo cholakwika sichiposa 0.005 mm.
3.Kutsuka keke ndi kuyeretsa
Mzerewo ukayikidwa mu keke yopanda kanthu yomwe yakhomeredwa ndi nkhonya, burr yaying'ono ndi m'mphepete mwake ziyenera kutsimikiziridwa. Pamwamba pa keke wobiriwira zouma ndi wapadera zotsukira. Keke iliyonse yobiriwira imayesedwa. Kulondola kwa sikelo yamagetsi kumafunika kukhala 0.0001g. Keke zonse zobiriwira zomwe sizikugwirizana ndi kulekerera ziyenera kuchotsedwa. Ikani mikate yobiriwira yofunikira mu chidebe choyera chokhala ndi chivindikiro molingana ndi kuchuluka kwake komwe kumayikidwa.
4. Nkhungu
Kupanga nkhungu ndi njira yapadera komanso yofunika kwambiri pakupanga ndalama. Pambuyo pofufuza mosamalitsa ndikuvomereza mutuwo ndi chitsanzo, kupyolera muzojambula zovuta komanso zokongola za timbewu ta timbewu ta timbewu ta timbewu timene timagwiritsa ntchito, kuphatikizapo kugwiritsa ntchito zipangizo zamakono zamakono, cholinga chokonzekera chinayikidwa pa nkhungu.
5. Chizindikiro
Kusindikiza kumachitika m'chipinda choyera ndi kusefera kwa mpweya. Kafumbi kakang'ono kalikonse ndiye kamene kamayambitsa kuchotsedwa kwa ndalama. Padziko lonse lapansi, chiwongolero cha kusindikiza nthawi zambiri chimakhala 10%, pomwe ndalama zochotsera ndalama zokhala ndi mainchesi akulu komanso malo owonera magalasi akulu ndi 50%.
6. Chitetezo ndi kulongedza
Pofuna kusunga mtundu wapachiyambi wa ndalama zachikumbutso za golide ndi siliva kwa nthawi inayake, pamwamba pa ndalama iliyonse iyenera kutetezedwa. Panthawi imodzimodziyo, imayikidwa mu bokosi la pulasitiki, losindikizidwa ndi filimu ya pulasitiki, kenaka ndikuyika mu bokosi lokonzekera mwapadera. Zinthu zonse zomalizidwa ziyenera kuyang'aniridwa mosamalitsa
