Yakarasika nzira yekukanda wakisi

Gold casting technique ndeimwe yekare, kana isiri iyo yakare-kare yezvishongo maitiro. Ndarama, seimwe yesimbi shoma, iripo muchimiro chayo chekuzvarwa, i.e. muchimiro chesimbi, kwete ore, izvo zvinoda kushanda nesimba kuti uwane simbi yakachena kubva mairi. Ndarama yekuzvarwa haigari yakachena, kazhinji kacho ine diki musanganiswa wesirivheri, mhangura kana platinamu, iyo, zvisinei, isingachinji maparamita ayo, uye kana zvasvika kune zvishongo, kusvibiswa kune mhedzisiro yakanaka pamagetsi paramita yealloy.

Yakarasika wakisi nzira - chii?

Maitiro ekukanda angaratidzika seakapusa, ari nyore, uye akachipa. Asi ichi chitarisiko chete, kunyangwe neazvino tekinoroji mhinduro, anofarira kutamba pranks. Imwe nzira inopa yakakwira mwero wezvakanakisa kubereka ndeye wakarasika wakisi nzira. Iri muchokwadi chekuti modhi iri kugadzirwa, kana kuti prototype yechinhu chatinoda kukanda kubva wakisi. Next tinodurura neakakodzera gypsum substance kuti iite mold. Kana mold yaoma, bvisa wakisi kubva mairi nekuipisa kusvika kune tembiricha yaunoda. Wax inoyerera kunze, chisipo chinogadzirwa muforoma nenzira yeprototype.

Zvese iwe zvunofanirwa kuita kurizadza nesimbi yakakosha yakanyungudutswa, mirira kuti itonhore, bvisa mold uye isu tine yakapedzwa, simbi chinhu chatinoenderera mberi nekugadzirisa. Zviri nyore, handizvo here? Basa rese re jeweler rakanangana nekugadzira iyo chaiyo wax prototype. Uye izvi zvinoda tarenda rekuveza, kururamisa uye kushivirira. Kunyanya kushivirira apo kukanda kwakundikana uye basa rakarasika risingadzoreki rakaiswa mukugadzira modhi rinofanirwa kudzokororwa.
