Premium High Purity Graphite Mold for Jewelry Melting

Product Description

        Graphite mold for gold jewerly melting and casting

 

       Well thermal stability : according to the using conditions of graphite crucible snap heat and cold;

     Well corrosion resistance, impact resistance performance, to ensure the reliability of product quality;

     Well resistance to strong acid, strong alkali;

   Good heat transfer performance of graphite crucible: for greatly shorten the melting time and save energy;

  In high-temperature using process, it got small thermal expansion coefficient;

 Utilization
Graphite crucible is generally used in alloy tool steel smelting and smelting of nonferrous metals and their alloys.
Graphite crucible can be used in the processing of graphite; graphite crucible; graphite casting crucible tank;pull rods; mold and other graphite products.
Graphite crucible let the products are more durable than ordinary material products;longer service life; able to withstand more than 2600 ¡ãC high temperature

Graphite melting Crucible

1. Good thermal stability, considering sudden heat and cold working condition, we apply special raw materials.

2. Impact resistance: Graphite crucible can withstand strong heat impact, therefore your can use it for any workmanship process.
3. Good thermal conductivity: Due to its high thermal conductivity, you can shorten melting time, saving energy.
4. Ash content is less than 300pp, melting metal can not be polluted during melting process.
