Vacuum Plating Tungsten Wire

Introduction

Vacuum plating tungsten wire is made by using natural gas heat treatment, it can reduce the damage of surface. The surface is brighter, cleaner by ultrasonic cleaning polishing process. This type of tungsten wire is one of the best products for the coating for its good corrosion resistance, high temperature performance, and long life time, it is widely used in mirror industry, kinescope industry, vacuum plating thin film technology and metal evaporation. Types of vacuum plating tungsten wire includ door shape, straight shape, peak shape, wave shaped, cone shape. Coated tungsten wire is mainly used in cosmetics industry, electronic products, vacuum plating glasses (heels, commodity, sun hat, glasses, helmets).

Classification

Tungsten wire of door shape surface has the function of adsorption of liquid aluminum, so that aluminum can diffuse uniformly, evaporate quickly and it would not form aluminum ball in vacuum melting state. Door shape tungsten wire stranded by tungsten wire tungsten wire has the large space, so liquid aluminum can be easily absorbed. Straight shape tungsten wire has characteristic with high temperature and anti-sag performance, which is mainly applied for evaporating silicon dioxide or powdered particles of metal box. Vacuum plating tungsten wire is flexible, and it is difficult to be broken by natural gas heating. Surface is cleaner, brighter and more smooth by ultrasonic cleaning process to ensure the quality of workpiece plating. In the manufacturing process of peak shape tungsten wire, there is not electric injury for the surface, which can greatly extend the life time of tungsten wire. Appropriate voltage of wave shaped tungsten wire is 24V, the lamp current is 20A, it is mainly used as heating element for vacuum plating. Cone shape tungsten wire, also known as funnel shape, its intersecting surface is circular, it is widely used in vapor deposition processes.
