Production process of tungsten carbide die
1, Soon after the order is confirmed,tungsten carbide die products will start to prepare the RTP powder as per customer's requirement with our wet-grinding machine

2, Before mass production, we need to do a trial pressing and sintering using every mould, and we check the appearances and the sizes of tungsten carbide die samples with micrometer, projectors etc. to ensure that the requirements of the drawings can be met before batch production

 

3, Bulk production ,press the raw materials to shape blanks,and all tungsten carbide die blanks must be passed by semi finished inspection

4, Then sinter blanks to finish (HIP) and finished tungsten carbide die inspection, we have 10 sets of vacuum sintering furnace and 2 setz of HIP in the factory ensure the best quality and production capacity.

5, 1). cleaning/tumbling is to make the tungsten carbide die look more beautiful.
    2).The tungsten carbide die can be ground according to customers' order tolerance requirement
