Double Arch Tungsten Heater
Double arch tungsten heater, also known as double peak tungsten heater, is a resistance high-temperature evaporation heating element manufactured from high-purity tungsten wire or stranded tungsten wire through precision forming. It is mainly used in vacuum evaporation coating systems and high-temperature thermal field applications.
Double arch tungsten heater features:
(1) Double-peak thermal field structure: Expands heating area and improves evaporation uniformity, suitable for high-load or uniform coating applications
(2) High-temperature stability: Operating temperature range approximately 1800–2600°C for continuous high-temperature operation
(3) High thermal efficiency: Concentrated heat distribution, rapid heating response, and stable evaporation rate
(4) Excellent deformation resistance: Tungsten melting point reaches approximately 3422°C, maintaining strong creep resistance and structural stability above 2000°C
(5) Low contamination: Low vapor pressure minimizes high-temperature volatilization and helps maintain vacuum cleanliness and film purity
(6) Suitable for continuous processing: Designed for long-term stable evaporation and high-load coating conditions
Double arch structures are widely used for vacuum evaporation of aluminum, silver, copper, nickel, and chromium, serving as critical heating elements in automotive lamp aluminizing, optical coatings, consumer electronics metallization, OLED (Organic Light Emitting Diode) processing, and semiconductor thin-film deposition, and laboratory vacuum evaporation systems.
