CTIA's Tungsten Heater in Plastic Coating
CTIA's tungsten heater in plastic coating refers to a resistive heating element used in vacuum evaporation coating equipment to heat and evaporate metals such as aluminum, tin, or chrome. By providing a stable, high-temperature thermal source, it enables uniform vaporization of metals in a high-vacuum environment. These metal vapors deposit onto plastic substrates including Acrylonitrile Butadiene Styrene (ABS), Polycarbonate (PC), and Polypropylene (PP) to form decorative or functional metallic thin-film layers serving automotive components, cosmetic packaging, and consumer electronics.
Working Principle of CTIA’s Tungsten Heater
Tungsten heater generates Joule heat upon electrification, heating the evaporation material to a molten and vaporized state. Metal atoms diffuse in the vacuum environment and deposit onto the plastic substrate surface, forming a dense and uniform metallic film after cooling to achieve plastic surface metallization.
