Ningbo De-Shin na-enye tungsten ọla ọcha zuru oke maka mpaghara ngwa ụlọ ọrụ dị iche iche.Ọ na-ewe usoro ntinye oghere oghere dị elu yana ngwaahịa niile na-agbaso ụkpụrụ nke GB/T8320-2003, ASTM B631.

Usoro mmepụta:ntụ ntụ mix -> ịpị -> sintering -> agụụ infiltration -> machining -> QC.Usoro mmepụta a niile bụ nke QC na-achịkwa nke ọma iji hụ na arụmọrụ kacha mma.

Uru:

1. Igwe ọkụ eletrik dị elu.

2. High thermal conductivity.

3. High njupụta na zuru okè uniformity microstruction nke ihe onwunwe.

Ngwa:

1. Ndị na-agbaji sekit.

2. Ndị na-agbaji mmiri n'ụwa.

3. Obere sekit breakers.

4. eguzogide ịgbado ọkụ electrode.

5. eyi osisi mgbochi
