Investment Kudzingwa kunonzi zvakare kwakarasika wakisi kukanda kana kunyatso kukanda, inova nzira yesimbi inogadzira kuburitsa zvikamu zvine tight tolerances, yakaoma yemukati matanda uye chaiwo mamipimo.
Investment Kudzingwa inzira yekugadzira iyo iyo wax pateni yakaputirwa neyakavhenekera zvedongo zvinhu. Kamwe iyo zvedongo zvinhu zvaomesa yayo yemukati geometry inotora chimiro chekukanda. Wakisi inonyungudika uye simbi yakanyungudutswa inodururwa mudumbu makanga muine wakisi pateni. Iyo simbi inosimbiswa mukati meiyo ceramic mold uye ipapo iyo simbi yekukanda yatsemuka. Iyi nzira yekugadzira inozivikanwa seyakarasika wax maitiro. Kukanda kwekudyara kwakagadzirwa kudhara zviuru zvemakore apfuura uye kunogona kudzika midzi yayo kumashure ese ekare eEgypt neChina.
Maitiro makuru akaita seanotevera:
Muenzaniso wekusika - Iwo wax mapatani anowanzo jekiseni akaumbwa musimbi kufa uye anoumbwa sechinhu chimwe chete. Makore anogona kushandiswa kuumba chero zvemukati maficha pane iyo pateni. Akawanda emapateni aya akasungirirwa kune yepakati wax gating system (sprue, vamhanyi, uye risers), kuti vagadzire semuti-senge musangano. Iyo gating system inoumba iwo makwara ayo ayo esimbi yakanyungudika inoyerera ichienda kune iyo mhango mhango.
Kugadzirwa kwevhu - Uyu "muenzaniso muti" wakanyikwa mune slurry yeakanaka zvedongo zvimedu, zvakaputirwa neakanyanya kuwanda zvimedu, uye ndokuzoomeswa kuita ceramic goko rakatenderedza mapatani uye gating system. Maitiro aya anodzokororwa kudzamara gobvu rave gobvu rakaringana kumira simbi yakanyungudutswa yaachasangana nayo. Goko iri rinobva raiswa muhovhoni uye wakisi inonyungudika kunze ichisiya gomba rehombodo yekiramiki rinoita sechiumbwa chimwe chete, ndokudanwa kunzi "wakisi yakarasika" kukanda.
Kudira - Iyo furuu inotungidzirwa muchoto kusvika pa1000 ° C (1832 ° F) uye simbi yakanyungudutswa inodururwa kubva mudhira kupinda mugate system yeforoma, ichizadza iyo mhango mhango. Kudira kunowanzoitwa nemaoko pasi pesimba regiravhiti, asi dzimwe nzira dzakadai sekutsvaira kana kumanikidza dzimwe nguva dzinoshandiswa.
Kutonhora - Mushure mekunge chakuvhuvhu chazadzwa, simbi yakanyungudutswa inobvumidzwa kutonhorera uye kusimbisa muchimiro chekukanda kwekupedzisira. Nguva yekutonhora zvinoenderana neukobvu hwechikamu, ukobvu hweforoma, uye izvo zvinoshandiswa.
Kukanda kubviswa - Mushure mekunge simbi yakanyungudika yatonhora, chakuvhuvhu chinogona kutyorwa uye kukanda kwacho kwabviswa. Iyo ceramic mold inowanzo kuputswa uchishandisa majeti emvura, asi dzimwe nzira dzinoverengeka dziripo Kana dzangobviswa, zvikamu zvacho zvinopatsanurwa kubva kune gating system nekucheka kana kutonhora kutonhora (uchishandisa mvura senitrogen).
Kupedza - Kazhinji nguva, kupedzisa mashandiro akadai sekukuya kana sandblasting anoshandiswa kutsvedza chikamu pamusuwo. Kurapa kwekupisa dzimwe nguva kunoshandiswa kuomesa chikamu chekupedzisira.
