Application :Tungsten wire heaters are mainly used for heating elements such as picture tube, mirror, plastic, metal substrate, ABS, PP and other plastic materials on the surface of various decorative objects. Tungsten wire is mainly used as a raw material for the heater.
working principle ：Tungsten has a high melting point, high electrical resistivity, good strength and low vapor pressure, making it suitable for use as a heater. The membrane is placed in a heater in a vacuum chamber, and heated under a high vacuum condition by a heater (tungsten heater) to evaporate. When the mean free path of the vapor molecules is greater than the linear size of the vacuum chamber, the atoms of the vapor After the molecules escape from the surface of the evaporation source, they are rarely affected or hindered by other molecules or atoms, and can directly reach the surface of the substrate to be plated. Due to the lower temperature of the substrate, the film is formed by condensation.
Thermal evaporation (resistance evaporation) is a coating method used as part of the PVD process (Physical Vapor Deposition). The material that is to form the subsequent layer is heated in a vacuum chamber until it evaporates. The vapor formed by the material condenses on the substrate and forms the required layer.
Our evaporation coils know how to turn up the heat: These resistance heaters with their very high melting points will bring practically any metal to the boil. At the same time, their high corrosion resistance and outstanding material purity prevent any contamination of the substrate.
