Kukanda jecha ndiyo nzira yakajairika yemhanguragaskets anoshandiswa mukugadzira jecha rekugadzira, iro rine zvakanakira kuchinjika kwakafara uye zviri nyore kugadzira kugadzira.Nekudaro, iyo dimensional yechokwadi, yemhando yepamusoro, uye yemukati mhando yekukandira inogadzirwa neiyi nzira iri kure nekusangana nezvinodiwa zvema mechanika zvikamu, uye maitiro ekugadzira akanyanya kuomarara, uye kuzadzikiswa kwekugadzirwa kwemakanika uye otomatiki kunoda mari yakakura.Mukugadzirwa kwezvimwe zvikamu zvakakosha uye zvakakosha zvehunyanzvi zvinodikanwa Zviratidziro zvehunyanzvi uye zvehupfumi zvakaderera, saka kushandiswa kwejecha rekukanda mukugadzirwa kwe foundry kunogumira kune imwe nhanho.Pamusoro pekukanda jecha, kukanda kwakakosha kwakagadzira nzira dzakasiyana dzekukanda dzakasiyana nejecha nekuchinja zvinhu zvekukanda, nzira yekudurura, fomu yealloy yemvura inozadza mold yekukanda, kana mamiriro ekusimba ekukanda.Vashandi veFoundry vanotaura kune dzimwe nzira dzekukanda dzakasiyana nejecha rekukanda seyakakosha kukanda.Yakajairika nzira dzakakosha dzekukanda muindasitiri yekugadzira michina ndeidzi:
1. Investment casting.Iyo inzira yekukandira isina-yakatemwa kana kushoma-yakatemwa-yakatemwa ine yakakwirira-dimensional kurongeka uye yakaderera pamusoro roughness kukosha uchishandisa fusible modhi uye yakakwirira-inoshanda makoko;metal mold casting.Iyo inzira yekushandisa simbi mold kuti iwedzere kutonhora kweyero yekukanda, kuwana imwe-yemhando yakawanda yekukanda, uye kuwana yekukanda ine dense crystalline chimiro.
2. Kudzvanya.Iyo inzira yekuwana chaiyo castings nekushandura kuzadza uye crystallization uye solidification mamiriro emvura alloys, kuitira kuti alloys emvura azadze molds pasi pekumanikidzwa kukuru uye mamiriro ekumhanya, uye kuumba uye crystallize pasi pekumanikidzwa kwakanyanya, nekudaro kuwana chaiyo castings;kurasika furo.Imhando yepurasitiki ine furo yakafanana nehukuru uye chimiro kune yekukandira, yakasungirirwa uye yakasanganiswa kuita mhuri yemuenzaniso, yakakweshwa neyakavharika coating uye yakaomeswa, yakavigwa mujecha requartz rekuvhima modhi, yozodirwa nesimbi yemvura pasi pemamwe mamiriro ekugadzira. modhi Nzira yekunyungudutsa uye kugadzira simbi yakanyungudutswa itore nzvimbo yemuenzaniso, uye kugadzira kukanda kunodiwa mushure mekunge simbi yakanyungudutswa yaoma uye kutonhora.
3. Low pressure casting.Inzira yekukanda pakati pegiravhiti inokandira mutobvu isina mhangura, iyo inoreva nzira yekupinza simbi yakanyungudutswa muforoma pasi pekuita kwesimba rinokwevera pasi, uye kukanda simba.Nekushandura mamiriro ekuzadza uye kusimba, iyo alloy yemvura inozadzwa zvishoma nezvishoma kubva pasi kusvika kumusoro pasi pemamiriro ekudzvinyirira uye yakaderera kumhanya, uye yakakwenenzverwa uye yakaomeswa sequentially kubva kumusoro kusvika pasi pasi pechiito chekudzvinyirira kwakaderera, kuitira kuti uwane yakakwirira- quality castings ine dense chimiro.
