Twisted spiral Tungsten Wire for Vacuum Coating film

Product Overview

Description

Tungsten Wire Filament Vacuum Metalizing Heater.

Our Advantage

1. Superior performance: long lifetime; shape is stable in using; small tolerance.

2. High quality raw materials: raw material is from state-owned enterprise. electric resistance is stable, tungsten is good at temperature rising, good in evaporation.

3. Professional: since 1991, in 28 years experiences in vacuum tungsten filaments production. we have the Professional team in research, production and sales. establish partnerships with at least 38 countries.

4. Service: you can get our quick response within 24 hours. 

It is suitable for use as heating for vacuum metalizing.The film material is placed in a heater in a vacuum chamber, and under high vacuum conditions, it is heated by a heater(tungsten twisted wire) to evaporate it . Mainly applied as heating element for vacuum metalizing in car light, mirror, plastic, ABS, PP and decorations etc.

Tungsten has a high melting point, high resistivity, good strength, and low vapor pressure.  When the mean free path of vapor molecules is larger than the linear dimension of the vacuum chamber, the atoms and molecules of the vapor escape from the surface of the evaporation source and are rarely impacted or obstructed by other molecules or atoms.
