Customize high pure carbon graphite mold for sale

Characteristics of graphite mold:

There are many kinds of Graphite Products, such as Graphite Crucible, graphite disc, Graphite Mold, Graphite Rod, graphite bolt and so on. Our company can customize these products according to the needs of customers. Graphite molds have many advantages.

1. High temperature resistance: the genera melting point of graphitemoldis 3850 ± 50℃, the boiling point is 4250℃, even after the ultra-high temperature burning, the weight loss is also very small;
2. High mechanical strength: the strength of graphite increases below 2500℃ with the increase of temperature. At 2000℃, the strength of graphitemoldis doubled, and the tolerable working pressure is also relatively large;
3. Excellent electrical conductivity and thermal conductivity: the electrical conductivity of graphite is 100 times higher than the general non-metallic ore, the thermal conductivity is more than steel, iron, lead and other metal materials. Its thermal conductivity is hundreds of times larger than the general non-metallic, 2 times larger than carbon steel. Good thermal conductivity makes the wholegraphitemold can achieve the effect of uniform heat transfer when working;
4. Low coefficient of thermal expansion: the low coefficient of thermal expansion of graphitemoldas the benefit of hot pressing mold is that the mold can withstand the sharp change of temperature without cracking. In addition, the metal will form a gap between the mold and the hot pressing process, which is easy to demold, will not damage the graphite mold, the mold can also be reused.
5. Good chemical stability: graphitemoldhas good chemical stability at room temperature. And graphite mold can resist acid, alkali and organic solution corrosion. In the hot pressing process, graphite will generate CO and CO2 protective gas layer, to protect the metal;
6. Easy to machining: graphitemoldcutting processing is convenient, but also can be viscose. It can be processed into high precision, various shapes of the mold.
