The main failure modes of glass bottle mould include oxidation (peeling, peeling, pitting), chamfering and deformation. The key factor affecting the service life of mould is the heat resistance of the material, which is the resistance to oxidation and the ability to resist growth at high temperature. This depends on the matrix and the form of the graphite.

Glass bottle die life with low tin vermicular iron and vermicular iron aluminum is highest, but low aluminum smelting and casting technology of vermicular iron is relatively complex, contains pearl size rarely, adverse to the resistance to wear, back to this, with a low tin vermicular iron production mold is more appropriate.
