Ceramic casting sand for sand 3d printing Featured Image

He one hoolei keramika no ke one pa'i 3d

ʻO ka wehewehe pōkole:

ʻO ke one Ceramic sintered ʻo Kaist, ʻo ia nā huahana like me Ceratech a i ʻole Cerabeads, he ʻano o ke one ceramic foundry kiʻekiʻe i hoʻohana ʻia no ka hana ʻana i nā mold a me nā cores no ka hoʻolei metala i nā huahana kiʻekiʻe i ka ʻoihana kaʻa, aila & kinoea, mining a me nā ʻoihana kūkulu. Loaʻa ia i nā poloka cylinder a me nā valve hydraulic, a me nā pumps, impellers a me nā mea hana. Hana ʻia ke one artificial Kaist me nā kristal mullite me ka maikaʻi paʻa loa. Hana ʻia lākou ma ke kī ʻana i nā granule spherical, ʻaʻole ma ka ʻoki ʻana iā lākou.

E hoʻouna i ka leka uila iā mākou

Huahana Huahana

ʻO ke one Ceramic sintered ʻo Kaist, ʻo ia nā huahana like me Ceratec's Nagai Cerabeads, he ʻano o ke one ceramic foundry kiʻekiʻe i hoʻohana ʻia no ka hana ʻana i nā mold a me nā cores no ka hoʻolei metala i nā huahana kiʻekiʻe i ka ʻoihana kaʻa, ʻaila & kinoea, mining a me nā ʻoihana kūkulu. Loaʻa kēlā me nā poloka cylinder a me nā valve hydraulic, a me nā pumps, impellers a me nā mea hana. Hana ʻia ke one artificial Kaist me nā kristal mullite me ka maikaʻi paʻa loa. Hana ʻia lākou ma ke kī ʻana i nā granules spherical, ʻaʻole ma ka ʻoki ʻana iā lākou.

E like me ke one 3D paʻi maka, i kēia manawa ua loaʻa i kā mākou mau hoa ʻo ExOne, Voxeljet, KOCEL, etc.

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.

ʻO ka hoʻohana ʻana i ke one ceramic foundry ʻo Kaist e hōʻemi ana i ka ʻōpala a me ka lepo, me ka waiwai reclamation kiʻekiʻe o nā mea. Eia kekahi, ua hoʻohana mua ʻia ke one ʻo Kaist ceramic foundry ma mua o 100 foundries ma ka honua holoʻokoʻa; hiki ke hoʻohana ʻia i nā kaʻina hana kuʻuna kuʻuna e hoʻopuka i nā hopena kiʻekiʻe me ke ʻano o nā metala, me nā kila (haʻahaʻa-alloy, carbon, a me nā kuʻekuʻe), hao (hina, ductile), aluminika, a me nā metala ʻē aʻe kahi e paʻa ai ka mana. a makemake ʻia ka pau ʻana o ka ʻili.
