Pōmaikaʻi

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.

Ma ke ʻano he mea kūʻokoʻa, pili ke one ceramic KAIST i nā resins acid a me ka alkali.

Hiki ke hoʻohana nui ʻia no ka hoʻolei ʻana i ka hao, ke kila a me ka hoʻolei ʻana i nā metala nonferrous, e like me ka hoʻolei ʻana i ka pahu, ke one i uhi ʻia, ke one resin, ka pahu pahu anuanu, ka hoʻolei pololei ʻana, a me ka paʻi 3D.
