Graphite crucibles and molds boast excellent heat resistance and stable performance. They fit metal smelting and sintering processes, serving metallurgy and new-energy industries extensively.

Advantages of Graphite Crucibles & Molds

  • 1

    Graphite's high-temperature resistance, maximum operating temperature.


  • 2

    Thermal stability, resistance to thermal shock, no cracking under rapid cooling and heating.


  • 3

    The benefits of thermal and electrical conductivity for melting.


  • 4

    Chemical inertness, does not react with some molten metals.


  • 5

    Low expansion coefficient, sintered molds are less likely to deform.


  • 6

    Comparison of graphite material costs with ceramic and quartz molds.

Graphite Crucibles & Molds FAQs

  • Q:

    What are graphite crucibles & molds?

    They are high-purity carbon-based high-temperature tools. With excellent thermal performance, they are widely used for metal melting, sintering and thermal forming under high-temperature conditions.

  • Q:

    What core advantages do graphite crucibles have?

    Outstanding heat resistance, good thermal-shock resistance, low thermal expansion and chemical inertness. They resist sudden temperature change and seldom react with most molten non-ferrous metals.

  • Q:

    What industries are graphite crucibles and molds applied to?

    Mainly for non-ferrous metal smelting, powder metallurgy, new-energy material sintering, precious-metal smelting, laboratory thermal test, diamond & hard-alloy sintering.

  • Q:

    Why do graphite crucibles crack easily?

    Rapid heating/cooling thermal shock, moisture absorption without pre-drying, mechanical impact, unreasonable charging, excessive local temperature.

  • Q:

    How to store graphite crucibles and molds?

    Store in dry, ventilated warehouse. Keep away from rain and moisture. Place cushion pads underneath, avoid direct contact with damp ground.

  • Q:

    Can you make custom graphite crucibles and molds?

    Yes. We support CNC machining according to drawings, including custom sizes, cavity shapes, special holes and grooves. Different graphite grain grades are optional.
