graphite mold for glass

graphite Molds for glass molding: Due to the chemical stability of graphite materials, they are not easily infiltrated by molten glass and will not change the composition of the glass. Graphite materials have good thermal shock resistance and small size changes with temperature. Therefore, graphite materials have been used in glass manufacturing in recent years. It has become an indispensable mold material and can be used to make molds for glass tubes, bends, funnels and other special-shaped glass bottles.

Product Details

Why glass made of graphite mold?

1. Excellent thermal and electrical conductivity

2. Low linear expansion coefficient, good thermal stability and resistance to heating shock

3. Resistant to chemical corrosion and does not easily react with most metals

4. At high temperatures (the sintering temperature of most copper-based matrix is above 800°C) the strength increases as the temperature increases.

5. Has good lubrication and anti-wear properties

6. Easy to process, good machining performance, can be made into molds with complex shapes and high precision

Summary: Graphite material has chemical stability, is not easily infiltrated by molten glass, and does not change the composition of the glass. The material has good thermal shock resistance, and its size changes little with temperature. It is a good choice for hot-bent glass.
