CTIA's Tungsten Heater in Mirror Manufacturing
CTIA's tungsten heater is a resistive heating component designed for mirror manufacturing. It is used to heat and evaporate metal coating materials during the vacuum deposition process for products such as glass mirrors and optical lenses.
Precision-engineered from high-purity or doped tungsten wire through advanced stranding, coiling, and surface treatment, the tungsten heater is utilized across diverse industries, ranging from the production of residential dressing mirrors and automotive rearview mirrors to solar reflectors and precision optical lenses.
Tungsten heater acts as an important heating unit in the vacuum evaporation stage of a glass mirror production line. It evaporates metals such as aluminum, silver, or chromium in a high-vacuum environment by applying electrical current. These metals then deposit uniformly onto glass substrates to form functional reflective layers for optical, architectural, and automotive applications.
Tungsten heater offers excellent adaptability to meet the strict requirements for high reflectivity and adhesion stability in the mirror industry. It maintains a stable thermal field structure during high-temperature evaporation because tungsten has a melting point of 3410°C, which prevents softening or deformation.
The tungsten heating element also enhances image clarity by minimizing film contamination, as tungsten maintains low vapor pressure in high-vacuum environments. It ensures a smooth evaporation process through specialized surface treatments that improve wetting and carrying capacities for metals like aluminum and silver. Furthermore, the tungsten heater remains structurally stable over multiple thermal cycles due to controlled material microstructure and doping, which effectively reduces equipment maintenance frequency.
Specifications of CTIA's tungsten heater are as follows:
Material: High-purity tungsten or doped tungsten wire.
Wire diameter: 0.2~0.8mm.
Stranding: Single-wire or multi-strand.
