Product Details
Product Description
Graphite ingot mold
Graphite mold is widely used in kinds of precision casting. It has advantages of high temperature resistant, high machining accuracy, temperature well-distributed, easy demoded and so on. Graphite mold will be bound to apply in more fields. It is used for casting precious metals (gold, silver, etc.)
Advantages:
1.Good thermal and electrical conductivity
2.Strong chemical stability
3.Good lubrication
4.Easily to be machined according to customers' designs.
5.Good thermal shock resistance
