Advantages of Tungsten Wire in Heating Glass Process

As a high-performance functional material, tungsten wire has shown multi-dimensional technological innovation value and application advantages in the field of heating glass process. Its unique physical and chemical properties not only break through the limitations of traditional heating technology, but also promote the evolution of glass products towards intelligence and efficiency.

1. Extreme Environment Adaptability

Tungsten has an ultra-high melting point of 3422℃. Compared with traditional materials such as nickel-chromium alloy (melting point of about 1455℃), tungsten wire can withstand the high temperature required for heating glass process, ensuring that the heating element continues to play a role in key processes such as glass melting, molding, and tempering.

2. Precision Thermal Field Control Capability

The resistivity of tungsten wire is moderate and uniform, and its unique resistivity-temperature linear relationship gives it precise temperature control capability. Through nanometer-level wire diameter control technology, uniform heating and temperature difference control of the glass surface can be achieved to avoid stress concentration or cracking risks caused by local overheating.

3. Material Compatibility

Tungsten wire has excellent chemical stability and is not easy to react with glass components at high temperatures, which prolongs the service life of the heating element and improves the efficiency of the glass heating process.

4. Rapid Response Capability

Tungsten wire has a high heating rate and can quickly reach the set temperature to meet application scenarios that require rapid heating or temperature adjustment, such as automotive defrosting glass, smart dimming glass, etc.

5. Flexible Manufacturing Empowerment

Tungsten wire has good flexibility and can be processed into complex shapes to meet the heating needs of special-shaped glass products and improve design flexibility.

6. Green and Environmental Protection

From the perspective of environmental protection and energy efficiency, tungsten wire heating glass has low energy consumption, and tungsten materials can be recycled, which is in line with the trend of green manufacturing.
