Custom Tungsten Heater
1. What Is Custom Tungsten Heater?Custom tungsten heater is a non-standard tungsten heating element engineered according to vacuum chamber geometry, heating zone configuration, or specific vacuum deposition requirements. Its structures are highly flexible, including multi-U configurations, wave-linear hybrids, frame structures with local bends, multi-point supports, and ring or radial designs. These geometries are designed to precisely match equipment layout, substrate shape, or material distribution requirements.
2.Manufacturing Process of Custom Tungsten Heater
CTIA GROUP uses high-purity tungsten wire (≥99.95%) or doped tungsten wire as the base material and forms it into tungsten heaters through systematic customized processing. The key processes are as follows:
(1) Precision Forming Process: Multi-axis Computer Numerical Control (CNC) bending equipment is used to achieve accurate three-dimensional wire forming, enabling complex geometrical designs with high dimensional control.
(2) Controlled Stress Relief: Segmented high-temperature annealing is applied to eliminate residual stress at bending points, ensuring structural stability under repeated thermal cycling.
(3) Surface Treatment Options: Chemical cleaning, acid cleaning, or electrolytic polishing are available to meet different vacuum purity and deposition requirements.
3.Features of CTIA’s Custom Tungsten Heater
(1) High Design Flexibility: Fully tailored geometries precisely match vacuum coating systems and electrode layouts, solving installation and coverage limitations of standard heaters.
(2) Tailored Thermal Field Distribution: Localized heating intensity can be adjusted by modifying bend density or wire geometry, enabling both uniform and region-specific heating profiles.
(3) Compatibility with Complex Materials: Special structures such as hooks, loops, or nested supports allow stable loading of irregular evaporation materials, including metal blocks and composite particles.
(4) Optimized Mechanical Stability: Structural reinforcement designs improve load-bearing capability under vertical or inclined installation conditions, reducing deformation caused by gravity.
4.Applications of CTIA’s Custom Tungsten Heater
(1) Aerospace and Defense: Used for advanced coating and oxidation-resistant thin films on non-standard aerospace components.
(2) Semiconductor and Advanced Packaging: Applied in irregular packaging structures and Micro-Electro-Mechanical Systems (MEMS) for precision metallization processes.
(3) High-End Optical Systems: Used for coating freeform optics, large-aperture aspheric mirrors, and complex reflective surfaces.
(4) Advanced Scientific Research: Used in Physical Vapor Deposition (PVD) systems for simulating customized thermal field environments in experimental studies.
