Ceramic kukanda jecha rejecha 3d kudhinda
Kaist sintered Ceramic sand, izvo zvakafanana zvigadzirwa neCeratec's Nagai Cerabeads, imhando ye premium ceramic foundry jecha rinoshandiswa kugadzira mold uye macores ekukanda simbi zvigadzirwa zvemhando yepamusoro mumotokari, oiri & gasi, migodhi uye maindasitiri ekuvaka.Izvo zvinosanganisira cylinder blocks uye hydraulic valves, pamwe nemapombi, impellers uye zvishandiso.Kaist artificial jecha anogadzirwa ne mullite makristasi ane yakanyanya kugadzikana mhando.Iwo anogadzirwa nekupfura spherical granules, kwete nekuapwanya.
Sejecha 3D inodhinda mbishi zvinhu, ikozvino vatinoshanda navo vane ExOne, Voxeljet, KOCEL, nezvimwe.

Advantage
Kaist ceramic foundry jecha rinenge hafu sechiedza se zircon uye chromite, inenge yechitatu sechiedza sejecha rakabatanidzwa redomi.Kuenzaniswa nejecha rechisikigo uye mamwe madhiri edhisheni (iyo zvinhu zvinokwanisa kushandura zvakapetwa kaviri nhamba yezviumbwa pahuremu hweyuniti).Kaist ceramic foundry jecha inogona kuunza mold uye core package ine huwandu hwemabhenefiti ayo anosanganisira yakakwirira-simba rekukanda jecha mapakeji, ane yakanyanya kupisa kupisa, kuderera kwekuwedzera kwemafuta, yakagadziridzwa chikamu chekupedzisira kugadzirisa uye kutsetseka kwepamusoro pekupedzisira.Inogona zvakare kubatwa zviri nyore, kuchengetedza vashandi uye kutamisa simba mari.Nekudaro, mugadziri anokurudzira kutarisisa kune huwandu hwekuwedzera binder.
Application
Kushandisa Kaist ceramic foundry jecha zvakare kunoderedza marara uye guruva, ine yakakwirira reclamation kukosha kwezvinhu.Mukuwedzera, Kaist zvedongo foundry jecha vari kutoshandiswa panguva dzinopfuura 100 foundries munyika yose;anogona kushandiswa mumaitiro echinyakare ekugadzira mold kuendesa mhedzisiro yemhando yepamusoro nemhando yesimbi, kusanganisira simbi (yakaderera-alloy, kabhoni, uye isina tsvina), simbi (grey, ductile), aruminiyamu, uye dzimwe simbi uko kusimba kunodzora. uye kupera kwepamusoro kunodiwa.
Zvikamu zveParticle size Distribution
Iyo particle size yekugovera inogona kugadzirwa zvinoenderana nezvaunoda.
