Multi Strand Tungsten Heater
1.What Is Multi Strand Tungsten Heater?
Multi strand tungsten heater is a tungsten heating element formed by twisting two or more tungsten wires together at a defined pitch, followed by shaping into final geometries. It can be designed into M-shaped, U-shaped, Z-shaped, V-shaped, or U-frame structures.
2.Advantages of CTIA’s Multi Strand Tungsten Heater
(1) High-Temperature Deformation Resistance: The multi-strand bundle structure provides strong mechanical support, effectively delaying creep at temperatures above 2000°C and reducing sagging or positional deviation caused by gravity.
(2) High and Stable Material Loading Capacity: Deep spiral grooves increase surface area, enhance molten metal adhesion, prevent material flow, and improve single-cycle evaporation capacity.
(3) Wide Thermal Field Coverage: Multi-wire contact ensures uniform current distribution, forming a wide and stable linear thermal field, which helps achieve uniform film thickness on large-area substrates.
3.Applications of CTIA’s Multi Strand Tungsten Heater
(1) Automotive Industry: Used for surface metallization of large components such as headlamp reflectors and wheel covers. As an evaporation source, it enables uniform deposition of aluminum or chromium on complex geometries under vacuum conditions.
(2) Display and Consumer Electronics: Used for reflective films in Liquid Crystal Display (LCD) backlight modules and decorative coatings on mobile phone housings. Stable thermal radiation ensures dense metal film formation on plastic or glass substrates.
(3) Optics and Decoration: Used in large-area mirrors, architectural metal decoration components, and metallization processes for semiconductor power devices, serving as a key evaporation source for melting and vaporizing metals.
