The Company's graphite product uses a
special high-purity, high-strength,
high-density graphite materials, and through
the excellent technical personnel, as well
as high-precision digital control processing
equipment and other production made, to
provide customers with excellent performance
graphite melting crucible, casting crucible,
graphite sump, trombone, tab, pull the stick
mold graphite products.
The Company Featured Special Purpose
material allows the graphite crucible
products than 2 times higher than ordinary
materials, product durability, longer life,
more can withstand the high temperatures of
more than 2000 ℃!
But also has the following characteristics:
1.Good thermal stability, for the the
graphite crucible rapid thermal quenching
conditions of use, in particular
2.Good corrosion resistance, impact
resistance, and to ensure the reliability of
the product quality.
3.Good resistance to acids, alkalis.
4.Good thermal conductivity, can greatly
shorten the melting time, save energy.
5. 300pp ash, to
ensure that the precious metals smelting
Selected fused silica as the main raw
material, made through modern ceramic
technology processing, mainly for platinum,
gold, and other high-temperature alloy
