Yakasiyana-siyana yekukanda maitiro akagadzirwa nekufamba kwenguva nevakatanga nevatsvaguri, imwe neimwe iine hunhu hwayo uye mashandisirwo eiyometal castingskusangana neakananga engineering uye sevhisi zvinodiwa. Kazhinji kutaura, zvinoenderana kana mold yekukanda ichigona kushandiswa zvakare kana kuti kwete, maitiro ekukanda anogona kupatsanurwa kuita Expendable Mold Casting, Permanent Mold Casting uye Composite Mold Casting. Iyo inodhura yekuumbwa mold inogona zvakare kukamurwa kuitakukanda jecha, kukanda shell mold,Investment castinguye yakarasika kukanda furo, nepo chisingaperi kukanda kuumbwa kunovhara giravhiti kufa kukandira, kuderera kwemhepo kunofa kukanda uye kukanda kukuru kunofa.
1. Expendable Mold Casting
Zviumbwa zvinodhura zvinowanzogadzirwa nejecha, plaster, ceramics, nezvimwe zvakafanana. Kazhinji inosanganiswa nemabhainda akasiyana, kana ma bonding agents. Chiumbwa chejecha chine 90% jecha, 7% yevhu, uye 3% mvura. Zvinhu izvi zvinoramba (kutsungirira kupisa kwakanyanya kwesimbi yakanyungudutswa). Mushure mekunge kuumbwa kwaoma, mold inogona kushandiswa mumaitiro aya inotsemuka kuti ibvise simbi yekupedzisira.
2. Permanent Mold Casting
Zviumbwa zvechigarire zvinonyanya kugadzirwa nesimbi dzinochengetedza simba pakupisa kwakanyanya. Vanoshandiswa kakawanda. Yakagadzirwa kuitira kuti simbi inokanda inogona kubviswa nyore uye mold inogona kushandiswa zvakare. Iyo yekusingaperi mold casting inoshandisa zvirinani kupisa conductor pane inowedzeredzwa nonmetallic molds; saka, kuomesa kukanda kunoiswa kune yakakwira mwero wekutonhora, iyo inokanganisa iyo microstructure uye saizi yezviyo.
3. Composite Mold Casting
Zviumbwa zvakaumbwa zvinogadzirwa nezvinhu zviviri kana kupfuura zvakasiyana (sejecha, graphite, uye simbi) zvichibatanidza zvakanakira chinhu chimwe nechimwe. Iwo akaumbwa mold ane chikamu chisingaperi uye chinodhura uye anoshandiswa muakasiyana ekukanda maitiro ekuvandudza kusimba kweforoma, kudzora kutonhora mitengo, uye optimize hupfumi hwese hwekukanda maitiro.
