What is Tungsten Basket?
Tungsten basket is a tungsten heating element that looks like a small metal mesh basket. It is typically made from tungsten wire or stranded tungsten wire through winding, weaving or spot welding processes, and is also known as tungsten evaporation basket.
During operation, metal materials such as aluminum or silver pellets are placed directly into the basket. When current passes through, the tungsten basket generates heat, gradually melting and evaporating the materials. Unlike conventional heating elements, the tungsten basket functions not only as a heating source but also as a material holder, integrating heating and loading in a single structure.
Based on CTIA GROUP’s manufacturing experience, the basket structure offers good operational stability. Materials are confined within the basket body, reducing loss and enabling more controlled evaporation. The heating zone is relatively concentrated, which helps improve evaporation uniformity. It is especially suitable for high evaporation rates and continuous production processes. In addition, the simple loading method improves operating efficiency.
Tungsten baskets are commonly used evaporation sources in Physical Vapor Deposition (PVD) resistance heating evaporation processes. They are widely applied in the evaporation of metals such as aluminum, silver and gold, and are also used in optical coating, decorative coating, capacitor metallization and laboratory vacuum evaporation systems.
CTIA GROUP uses high-purity tungsten wire (≥99.95%) to ensure stable performance under high-temperature and vacuum conditions while reducing contamination in vacuum coating processes. With over 30 years of experience in tungsten heater manufacturing, CTIA GROUP provides customized solutions including material selection, structural design, heating zone configuration and connection methods. Supported by advanced surface treatment processes, CTIA GROUP delivers full-process customization from material selection to precision manufacturing.
