Graphite Products for Glass Industry

BZNCarbon supplies high-performance, precision-machined graphite components specifically designed for the glass industry. With excellent resistance to deformation at elevated temperatures and low wettability to molten glass and metal, graphite is the ideal material for use in the float glass and glass bottle production processes.

Our graphite products are available in large sizes and high-strength formulations, and can be custom-machined to meet a variety of industrial needs. For enhanced durability, we also offer anti-oxidation treatment to extend product service life under high-temperature, oxygen-rich conditions.

Product Description

Graphite’s non-reactive surface and high-temperature stability make it essential in many stages of glass production. Key applications include:

  • Float Glass Production
    Graphite barriers and supports in tin bath walls, often up to 3–4 meters in length, provide structural guidance and containment for the float glass process. These components are dimensionally stable and resist wear even under intense heat and chemical exposure.

  • Glass Bottle Molding
    Graphite molds and fixtures offer precise shaping and easy release in bottle forming applications, where thermal cycling and surface smoothness are critical.

To ensure protection during long-distance shipping, our large-format graphite components are specially packed to prevent cracking, chipping, or deformation.
