3, Bulk production ,press the raw materials to shape blanks,and all carbide forging die blanks must be passed by semi finished inspection,
4, Then sinter blanks to finish (HIP) and finished products inspection, we have 10 sets of vacuum sintering furnace and 2 sets of HIP in the factory ensure the best quality and production capacity.
5, 1). cleaning/tumbling is to make the carbide forging die look more beautiful.
