Tungsten Coiled Filament
We are the manufacture of single or multiple strand tungsten coil filament for evaporation over 20 years, samples could be provided for your quality test.
Bless uses high-quality tungsten wires as raw materials, after automatic straightening, cleaning, and polishing, finishing producing tungsten heating coil for vacuum metalizing. Single or multiple spiral tungsten heating coil for evaporation source could be provided by Bless. Many shapes of filament heater for coating are what we specialized.
Bless uses high-quality tungsten wires as raw materials, after automatic straightening, cleaning, and polishing, Bless can efficiently and quickly produce tungsten filament with high melting point, good corrosion resistance and long evaporation life according to your needs.
What shape of tungsten heating coil Bless produce?
The diameter specifications can be customized according to customer requirements. W type, cup type, coil type, NC3 double type of tungsten coil heater for evaporation are available.

Bless Production Process of Tungsten Filament
What is the application of Tungsten filaments?
The benefits of using tungsten metalizing filaments for your evaporation process include low cost, long life, high rates with low power, repeatability and ease of use. Custom fabrication is available upon request.
. - Semiconductor devices - Picture tubes - Vacuum furnace heating elements
. Vacuum coating / Evaporation
- Mirror - Plastic - Metal substrate - Various decorative surfaces
Meanwhile, the vapor-deposited metal wire and the tungsten wire can be twisted together to make the product more convenient and quick.

Quality Inspection
·Flaw Detection
Corresponding tests for each process of Tungsten wire. Under flaw detection, there are Grade A (2 crack points per 100 meters), B, C Grade. The more cracks, the more easily the filaments are broken during processing. We will choose different standard according different request for quality grade.
·Equipment
A rolling mill introduced from Germany, which it can be deeply process the rod core, which can make the inside struction more uniform. Unlike the early traditional technology, are mainly surface processing.
·Property
Online measuring device in the wire drawing process, which can monitor the overall diameter uniformity.
