• Kuchuluka kwamadzimadzi komanso kudzaza bwino chifukwa chokhala ozungulira
• Mlingo wapamwamba kwambiri wobwezeretsanso mumchenga wa loop system
Kugwiritsa Ntchito Sand Foundry Njira
RCS (mchenga wokutidwa ndi resin)
Cold box mchenga ndondomeko
3D kusindikiza mchenga ndondomeko (Phatikizani Furan utomoni ndi PDB Phenolic utomoni)
Njira ya mchenga wosaphika (Phatikizanipo utomoni wa Furan ndi Alkali phenolic resin)
Njira yopangira ndalama / Kutayika kwa sera yotayika / Kuponyera mwatsatanetsatane
Njira yotaya thupi / Kutaya thovu

Kufotokozera
Super Ceramic Sand ndi mchenga wopangidwa ndi munthu wokhala ndi mawonekedwe ozungulira.Amadziwika ndi mayina ambiri kuphatikiza Ceramic Sand, Cerabeads ndi CeramCast, chisankho chabwino kwambiri pamakampani opanga mchenga.
Chimodzi mwazabwino zazikulu za mchenga wa ceramic ndi kukana kwake kwakukulu.Kuonjezera apo, mankhwalawa alibe pafupifupi kuwonjezereka kwa kutentha, zomwe zikutanthauza kuti zimasunga mawonekedwe ake ngakhale pali kusintha kwakukulu kwa kutentha.
Super Ceramic Sand ilinso ndi mbali yabwino kwambiri, zomwe zikutanthauza kuti imayenda momasuka mozungulira mawonekedwe ovuta komanso zovuta.Izi zimapangitsa kukhala yabwino kwa castings zovuta ndi zisamere nkhungu.
Chinthu chinanso chochititsa chidwi cha Super Ceramic Sand ndi kuchira kwake kwakukulu.Izi zikutanthauza kuti mankhwalawa amatha kugwiritsidwanso ntchito nthawi zambiri, zomwe sizimangochepetsa zinyalala, komanso zimapulumutsa nthawi ndi ndalama zopanga.Mlingo wapamwamba wobwezeretsa umatanthauzanso kuti mankhwalawa ndi ochezeka ndi chilengedwe chifukwa amachepetsa kuchuluka kwa zinthu zomwe zimayenera kukumbidwa ndikukonzedwa.
Pomaliza, Super Ceramic Sand ndiwosintha masewera pamakampani opanga mchenga.Ndi ntchito yake yapamwamba komanso kukhazikika kwapadera, ndi yabwino kwa ma castings ovuta komanso zisankho.Kuchuluka kwake kobwezeretsanso komanso ubwino wa chilengedwe kumapangitsa kukhala chisankho chodalirika komanso chokhazikika kwa opanga.
