Double-Strand Twisted Tungsten Heater
1.What Is Double-Strand Twisted Tungsten Heater?Double-strand twisted tungsten heater is a tungsten heating element formed by precisely twisting two high-purity tungsten wires at a defined pitch, followed by shaping and forming processes. This structure is designed to increase the effective cross-sectional area and surface area of tungsten wire, overcoming the limitations of single-strand tungsten wire heaters in load capacity and thermal field distribution.
2.Advantages of CTIA’s Double-Strand Twisted Tungsten Heater(1) Enhanced Material Adhesion
The helical structure formed by two twisted tungsten wires increases surface area and provides improved physical anchoring sites for evaporated materials such as aluminum and gold wires, effectively preventing material flow or detachment during melting.
(2) Improved Mechanical Strength
Compared with single-strand structures, the twisted dual-wire configuration offers higher tensile strength and structural support. At temperatures above 2000°C, it significantly reduces gravitational sagging and deformation, extending service life.
(3) Optimized Thermal Field Distribution
Electrical current is more evenly distributed through the contact between the two tungsten wires, generating a wider and more stable thermal field, which supports uniform evaporation and improves film thickness consistency.
3.Applications of CTIA’s Double-Strand Twisted Tungsten Heater(1) Automotive Metallization
Used for surface coating of automotive headlamp reflectors, wheel trim covers, and interior components, ensuring excellent coating brightness and adhesion strength.
(2) Precision Display Technology
Applied in reflective film deposition for Liquid Crystal Display (LCD) backlight modules and precision coating of large-area optical lenses.
(3) Electronic Component Manufacturing
Used in metallization processes for semiconductor power devices, suitable for evaporating high-conductivity metals such as aluminum, silver, and copper.
