CTIA's Tungsten Heater in Decorative Coating
CTIA’s tungsten heater is an evaporation heating element used in decorative vacuum metallization processes to heat and vaporize metals such as aluminum, silver, gold, copper, and chromium. The tungsten heating element is fabricated from high purity tungsten wire through precision stranding, coiling, forming, and surface purification, offering excellent high temperature stability and evaporation adaptability.
The tungsten heater enables stable metal vaporization through resistive heating in a high vacuum environment, allowing uniform deposition onto substrates such as metal, ceramic, glass, or plastic. The resulting decorative metal film features high gloss, vivid color, and strong adhesion for wide applications in consumer goods, handicrafts, and product appearance enhancement.
Decorative coating places strict requirements on color purity, mirror reflectivity, and surface defect control. CTIA’s tungsten heater provides stable process performance with the following characteristics:
Tungsten heater is extensively used for exterior components of daily necessities, handicrafts, cosmetic packaging, home decoration, and consumer electronics. It is primarily utilized for decorative coating on plastic or metal surfaces to grant products a high-gloss metallic texture and aesthetic upgrade. Common applications include metallization treatments for high-end jewelry, watch components, smartphone frames, cosmetic caps and housings, lamp reflectors, and daily hardware, effectively enhancing visual appeal and added value.
