Z-Type Tungsten Heater
What Is a Z-Type Tungsten Heater?
A Z-type tungsten heater is a tungsten heating element formed by bending high-purity tungsten wire or doped tungsten wire into a Z-shaped structure. Its folded geometry extends the effective heating path within limited space, improving resistance distribution uniformity and localized heating performance.
Advantages of CTIA’s Z-Type Tungsten Heater
(1) Directional thermal field distribution: Alternating right-angle or obtuse-angle bends create a stepped heating profile with alternating straight and angled segments, enabling directional heat control suitable for strip or localized heating.
(2) Strong material retention: Bend points act as physical barriers, restricting molten metal flow along the axis and maintaining stable evaporation positions.
(3) High space utilization: Compact geometry allows longer tungsten wire within limited space, achieving higher power output.
(4) Structural stability: Multi-segment bends distribute thermal stress, reducing deformation and improving long-term operational stability.
Applications of CTIA’s Z-Type Tungsten Heater
(1) Continuous coating of strip substrates: Used in roll-to-roll Physical Vapor Deposition (PVD) systems for uniform coating of continuously moving films or metal strips, enabling stable deposition processes.
(2) Inner wall coating of tubular components: Applied in long tube internal coating via insertion or rotational evaporation, achieving uniform film coverage inside cylindrical structures.
(3) Precision resistor manufacturing: Used in thin-film deposition of resistive materials such as nickel-chromium alloys, ensuring consistent resistance distribution and stability.
(4) Special optical window coating: Used for non-circular substrates such as rectangular optical windows, ensuring uniform evaporation and consistent film coverage.
Z-type tungsten heater is preferred for long strip-shaped workpieces, limited installation space requiring high power density, or applications demanding high thermal stability and positional retention under high temperatures.
