Ningbo De-Shin na-enye ụdị tungsten ọlaọcha zuru oke maka ọrụ dị iche iche n'ụlọ ọrụ mmepụta ihe. Ọ na-ewe usoro ntinye oghere dị elu ma ngwaahịa niile na-emezu ihe achọrọ dịka GB/T8320-2003, ASTM B631.
Usoro mmepụta:Ngwakọta ntụ ntụ –> ịpị –> sintering –> ntinye vacuum –> igwe eji arụ ọrụ –> QC. Usoro mmepụta a niile bụ nke QC na-achịkwa nke ọma iji hụ na arụmọrụ kacha mma.
Uru:
1. Ike eletriki dị elu.
2. Oke ike okpomọkụ.
3. Nnukwu njupụta na nhazi zuru oke nke ihe.
Ngwa:
1. Ihe mgbawa sekit.
2. Ihe ndị na-emebi mmiri n'ụwa.
3. Obere ihe mgbawa sekit.
4. elektrọd ịgbado ọkụ na-eguzogide.
5. ogwe iguzogide iyi
