Classification
①Machined crucible
Machined tantalum crucible is mainly small crucible, generally tantalum rod as raw material, processed by lathe.
■ Advantages: good machined surface, high precision
■ Disadvantage: high cost
②Sintering crucible
Sintered tantalum crucible is a process in which tantalum powder is shaped by isostatic pressing technology and then sintered into tantalum crucible at high temperature in a vacuum environment. This process is suitable for large tantalum crucible.
■ Advantage: low cost
■ Disadvantage: accuracy is not easy to guarantee
③Welding crucible
Tantalum crucible welding process is to select the appropriate size of the tantalum sheet or tantalum foil, rolled into a cylindrical and welded, and then welded at one end of the cylinder plate, after the appropriate size correction and surface treatment process, the final production of qualified finished tantalum crucible.
■ Advantages: thin-walled crucibles can be made
■ Disadvantages: high requirements for welding sealing
④Stamped crucible
Stamping tantalum crucible process is the selection of high-quality tantalum or tantalum foil, with the appropriate mold, single or multiple stamping production. The process has the advantages of moderate cost, high dimensional accuracy and high mechanical performance. Suitable for small and medium-sized crucible production, has been widely used.
■ Advantages: high efficiency, moderate cost
■ Disadvantage: Increased cost when the number of products is too small
What kind of crucible can we provide
