Why use graphite material for 3D curved glass mould?
The utility model has the advantages of easy processing and good mechanical processing performance, and can be made into moulds with complex shapes and high precisionSummary: graphite material has chemical stability, is not susceptible to infiltration of molten glass, will not change the composition of the glass, the material has good thermal shock resistance, and the size of the change with the temperature is small, is the best choice for hot bending glass
At high temperatures (at most sintering temperatures above 800 Cu base), the strength increases with increasing temperatureGood lubrication and abrasion resistance
Excellent thermal conductivity and conductivityLow coefficient of linear expansion, good thermal stability and thermal shock resistanceChemical resistance is difficult to react with most metals
