Ceramic casting sand bakeng sa lehlabathe 3d khatiso

Tlhaloso e Khutšoanyane:

Kaist sintered Ceramic sand, e leng tsona lihlahisoa tse nang le Ceratech kapa Cerabeads, ke mofuta oa lehlabathe la premium ceramic foundry le sebelisetsoang ho theha hlobo le li-cores bakeng sa lihlahisoa tsa tšepe tsa boleng bo holimo indastering ea likoloi, oli le khase, merafo le kaho. Seo se kenyelletsa li-cylinder blocks le li-valve tsa hydraulic, hammoho le lipompo, li-impellers le lisebelisoa. Lehlabathe la maiketsetso la Kaist le entsoe ka likristale tsa mullite tse nang le boleng bo tsitsitseng haholo. Li hlahisoa ka ho thunya li-granules tse chitja, eseng ka ho li pshatla.

Molemo

Kaist ceramic foundry sand is about half as light as zircon and chromite, is about third as light as fused ceramic sand. Compared to these natural sand and other foundry media (the material is able to turn out about twice the number of molds per unit weight). Kaist ceramic foundry sand can deliver mold and core packages with a range of benefits that include higher-strength sand casting packages, with high heat resistance, low thermal expansion, improved final part resolution and a smoother surface finish. It can also be handled very easily, saving labor and transfer power costs. However, the manufacturer recommends paying attention to the amount of binder addition.
