Multi Peak Tungsten Heater

A multi peak tungsten heater is a tungsten heating element formed by precision bending high-purity tungsten wire into multiple peak structures, such as triple peak, quadruple peak, or continuous wave-like configurations. It consists of terminal leads and multiple continuous or parallel heating peaks. Compared with single peak and double peak designs, it provides a larger effective heating area and higher material loading capacity, making it suitable for high-load vacuum evaporation coating applications.

(1) Linear thermal field distribution: By increasing the number of peaks, point-source evaporation is transformed into a distributed multi-point linear heat source, improving large-area coating uniformity.
(2) High material loading capacity: The multi peak structure provides multiple material holding positions, allowing higher loading of evaporation materials such as aluminum wire and gold wire, extending operating time per cycle.
(3) High-temperature resistance: Tungsten has a melting point of approximately 3420°C and maintains structural stability under high-vacuum and high thermal load conditions without deformation or failure.
(4) Long service life with anti-sag performance: Doped tungsten wire improves high-temperature creep resistance, ensuring stable peak structure under continuous operation.
(5) High surface purity: Electrolytic polishing or chemical cleaning reduces surface impurities and outgassing, improving vacuum coating cleanliness.

3. Applications of CTIA’s Multi Peak Tungsten Heater
(1) Large-area flat panel displays: Used for large-area deposition of reflective layers and electrode films in display panels, ensuring uniform coating and consistent film quality.
(2) Automotive components industry: Applied in continuous vacuum metallization lines for headlights, reflectors, wheels, and interior/exterior decorative parts.
(3) Flexible packaging coating: Used in roll-to-roll vacuum coating systems to provide stable metal evaporation for plastic films.
(4) Large optical components: Used for metal coating of large-aperture lenses, astronomical telescopes, and aerospace optical systems.

(1) Material: High-purity or doped tungsten wire
(2) Wire diameter: 0.2–1.5 mm
(3) Structural parameters: Number of peaks, peak height, span, overall length, and lead length customizable
(4) Structure type: Multi peak parallel or continuous multi peak structure
(5) Strand configuration: Single wire or multi-strand twisted wire
(6) Surface treatment: Chemical cleaning or electrolytic polishing
