Product Description

Tungsten Coiled Filament

We are the manufacturer of single or multistrand 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 the tungsten heating coil for vacuum metalizing. Single or multiple spiral tungsten heating coils for evaporation sources could be provided by Bless. Many shapes of filament heaters for coating are what we specialize in.

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 points, 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,  and 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.
