PVD-Consumables - Filaments
Tungsten Filaments are made using proven fabrication processes and are of the highest quality, reliability and consistency in the industry.
Multi-strand filaments are generally preferred because they offer a greater surface area than single-wire filaments. Because of their simplicity and low cost, wire sources are also used to evaporate metals such as Al, Ni, Fe, or Pt which are known to alloy with Tungsten.
Under these conditions, the evaporant charge should be small compared with the mass of the filament, and the latter is quickly destroyed if the molten evaporant collects in one spot.
Custom fabrication is available upon request.
High quality coils – Perfect coating results
Our evaporation coils and filaments are manufactured from high purity raw materials with optimized grain structure. In combination with fast loading and exact conditioning of the evaporation material like aluminium our coils and filaments provide excellent coating results.
Summit-Tech coils and filaments are known for their improved coating performance due to high quality raw materials and improved surface characteristics (especially for the evaporation of aluminium coils). At the same time our unique manufacturing capabilities allow for high corrosion resistance and low defect rates in order to prevent any contamination of the substrate
