1.Sarudzo yezvinhu
Mari dzesirivha dzinowanzo shandisa sirivha chaiyo ine hutsanana hwe999, uye hutsanana hwe925 ne900 ndihwo hunonyanya kushandiswa pasi rose. Mari dzegoridhe dzinowanzo gadzirwa negoridhe nesirivha kana goridhe mhangura alloys dzakadai se999999 ne22K. Goridhe nesirivha zvinonatswa uye zvinogadzirwa ne mint kuburikidza nekunatswa kwe electrolytic, uye zvinoongororwa kuita madotsi nemidziyo yemazuva ano. Mhedzisiro yekuongorora inomiririra mwero wepamutemo uye kufambira mberi kwetekinoroji kwenyika.

2. Nyungudutsa ndiro yakamonerwa
Kubva muchoto chemagetsi, simbi yakanyungudutswa inokandwa muzvikamu zvakasiyana-siyana zvemabhillets kuburikidza nemuchina unokandwa nguva dzose, uye pamusoro payo panogayiwa nemashini kubvisa tsvina, uye pozobva pagumburwa nechando pasi pezvinodiwa zvakanyanya zvezvakatipoteredza. Pamuchina wekupedzisa wakakosha, girazi rakajeka rine kutsungirira kukora kudiki kwazvo rinogumburwa, uye kukanganisa hakupfuuri 0.005 mm.

3. Kusuka nekuchenesa makeke
Kana chidimbu chacho chikaiswa mukeke risina chinhu rakabayiwa nekurova, gomba diki uye mupendero wakanakisa zvinofanirwa kuve nechokwadi. Pamusoro pekeke regirini rinoomeswa nemuchina wekuchenesa wakakosha. Keke rega rega regirini rinoyerwa. Kururama kwechikero chemagetsi kunofanirwa kuva 0.0001g. Makeke ese egirini asingakwanirise anofanira kuraswa. Isa makeke egirini akakwana anodiwa mumudziyo wakachena une chivharo zvichienderana nehuwandu hwakatarwa hwekudhinda.

4. Chiumbwa
Kugadzira mold chinhu chakakosha uye chakakosha mukugadzirwa kwemari. Mushure mekunyatsoongorora nekubvumidza dingindira nepatani, kuburikidza nekugadzirwa kwakaoma uye kwakanaka kwemint, pamwe nekushandiswa kwemidziyo yemazuva ano chaiyo, chinangwa chekugadzira chakaiswa pamold.

5, Chinyorwa
Kudhinda kunoitirwa muimba yakachena ine mhepo inosefa. Guruva diki ndiro rinokonzeresa kudhinda mari. Pasi rese, kudhinda mari kunowanzova 10%, nepo kudhinda mari ine dhayamita yakakura uye nzvimbo yakakura yegirazi kuchisvika 50%.

6. Dziviriro uye kurongedza
Kuti mari yegoridhe nesirivha irambe ine ruvara rwepakutanga kwenguva yakati, pamusoro pemari yega yega inofanira kuchengetedzwa. Panguva imwe chete, inoiswa mubhokisi repurasitiki, yakavharwa nepurasitiki, yozoiswa mubhokisi rekurongedza rakagadzirwa zvakanaka. Zvigadzirwa zvese zvakapedzwa zvinofanirwa kuongororwa zvakanyanya.
