Product Overview
Graphite Welding Mold is a precision-machined graphite tooling component used for welding, brazing, and high-temperature joining processes.
Key Features
Uniform Heat Transfer Performance
Provides stable heat distribution during welding processes to support consistent joining quality.
High-Temperature Dimensional Stability
Maintains mold accuracy during repeated heating and cooling cycles with low thermal expansion and thermal shock resistance.
Non-Wetting Surface Performance
Reduces adhesion with molten metals such as copper and aluminum for easier demolding and cleaner finished parts.
High-Purity Graphite Material
Uses high-purity graphite materials to reduce impurity-related risks in welding applications.
