Graphite Mold Casting Graphite Mold Customize

Customize isostatic graphite mould casting graphite mold for silver gold ingot bar casting

From the dimension to material selection, our company keeps providing the best for customers. As the leading manufacturer, our graphite products have been widely applied in metallurgy, machinery, electronics and chemical industry, etc. Our graphite mold is manufactured by advanced production technique and equipment with characteristics of good conductivity, high temperature resistant, acid and alkali resistance, corrosion resistance, great resistance to thermal and mechanical shock, and easy processing characteristics.

 

Using instruction:

1.Avoid contacting of hot molten metals with water, oil, grease, etc. It may cause excessive 

   spatter and burns.

2. Do not uses in flammable vapors or dust, a fire or explosion may happen.

3. void fire, mould must be stored in dry, well-ventilated area, away from open flame and         excessive heat.

4. Avoid looking directly at the light of the reaction. It may irritate your eyes.

5. Wear safety glasses and leather gloves to use the mould.

 

 

The characteristics of our graphite material:

1. low electric resistance

2. high temperature resistance

3.  good electric and thermal conductivity

4.  high oxidation resistance

5.  greater resistance to thermal and mechanical shock

6.   high mechanical strength and machining accuracy

7.   homogeneous structure

8.    hard surface and good flexural strength
