product description

Graphite rods are often used in the glass blowing process. They are irreplaceable tools in the high-temperature shaping of glass. Their advantages are to solve process pain points and improve product quality and production efficiency.

Graphite rods can be used continuously in a high temperature environment of 1600°C. When operating in the glass melting zone, graphite rods can continue to work without softening and deformation, avoiding surface impurities caused by high-temperature oxidation of metal tools from contaminating the glass. The graphite rod has a low thermal expansion coefficient, which ensures its dimensional stability and makes it more precise when blowing complex shapes.

Graphite rods have self-lubricating properties, which also reduces their adhesion to glass and has a higher demolding success rate. They are especially suitable for the molding of high-viscosity materials such as lead-containing crystalline glass. The high thermal conductivity of the graphite rod can quickly balance the temperature gradient in the contact area, thereby preventing stress cracks caused by local sudden cooling of the glass.

In the blowing of borosilicate glass instruments, graphite rods are used as inner support molds to achieve precise shaping through precise heat conduction. In the production of colored glass artworks, the uniform thermal conductivity of graphite rods can reduce the stress at the interface of the color layers, making the transition of the color bands natural and reducing the defective rate. In addition, graphite rods can also be used as sealing supports for glass tubes, and their low adhesion properties can reduce the bubble rate on the sealing surface.
