Working Principle

Infrared Heating

Infrared emitters operate by converting electrical or chemical energy into thermal energy through a heated element, such as tungsten, quartz, or ceramic. This process results in the emission of infrared electromagnetic waves, which transfer energy primarily by radiation. The emission of these waves follows the Second Law of Thermodynamics, where heat flows from a hotter body to a cooler one. When the emitter reaches high temperatures—often between 1800°C and 2400°C—the emission of infrared radiation becomes intense and focused. The design of the emitter, including the use of gold or white oxide reflectors, directs the emission efficiently onto the glass surface.

The efficiency of this process depends on the emissivity of the glass. Materials like Pyrex, lead, and soda glass have high emissivity values, allowing them to absorb infrared radiation effectively. The wavelength of the emission plays a crucial role in the heating process. By tuning the wavelength to match the absorption characteristics of glass, manufacturers achieve faster, more stable, and energy-efficient heating. Medium-wave infrared heat, for example, penetrates glass surfaces efficiently, making it ideal for pressing, molding, and laminating. The emission of energy through radiation, combined with conduction and convection within the glass and surrounding air, ensures uniform temperature distribution.

Note: The rapid response time of infrared emitters—often reaching full operating temperature in just one second—enables precise control over the heating process. This capability reduces waiting times and increases throughput in glass manufacturing.

The following table summarizes typical operating parameters for an infrared emitter for glass press:
