Straight Bar Tungsten Heater
What Is a Straight Bar Tungsten Heater?
A straight bar tungsten heater is a linear heating element engineered from single or multi-strand high-purity or doped tungsten wire. Characterized by its rigid, streamlined configuration, it is designed for effortless integration and maintenance within vacuum systems. This geometry is ideal for evaporation processes requiring uniform linear heat distribution or specialized chamber configurations.

Features of CTIA's Straight Bar Tungsten Heater
CTIA's straight bar tungsten heater offers a high melting point, high electrical resistivity, excellent high-temperature strength retention and strong creep resistance. In vacuum environments, it maintains low vapor pressure and good chemical stability. During high-temperature evaporation processes, it minimizes contamination risk and delivers stable operating performance. It is suitable for continuous or intermittent evaporation coating processes.
Applications of CTIA's Straight Bar Tungsten Heater
As an evaporation heating source, tungsten heater is widely used in:
1. Cathode Ray Tube (CRT) manufacturing: metal layer evaporation inside CRT tubes.
2. Mirror manufacturing: uniform deposition of high-reflectivity aluminum films on glass surfaces.
3. Plastic coating: decorative or functional coatings for plastic parts such as Acrylonitrile Butadiene Styrene (ABS) and Polypropylene (PP).
4. Metal substrate coating: improving wear resistance, corrosion resistance or electrical conductivity.
5. Decorative coating: automotive components, consumer electronics exterior parts and similar products.
6. Laboratory research: new material evaporation tests and vacuum heating environment simulation.
With over 30 years of experience in refractory metal fabrication, CTIA GROUP provides technical solutions for tungsten heater design and manufacturing. The process involves the calibration of wire gauge, strand count, heating zone distribution, and terminal spacing based on specified power and thermal requirements. These heaters can be treated with electrolytic polishing or chemical deoxidation to meet vacuum compatibility standards. Through a vertically integrated manufacturing model, CTIA GROUP manages the entire transition from metallurgical selection to the delivery of precision-finished products.
