Production Process of Tungsten Carbide Stud for High Pressure Grinding Rolls HPGR

To ensure the quality and the requirements of the drawings can be met before mass production

1st:, Start to prepare the RTP powder as per customer’s requirement with our wet-grinding machine

2nd, Before mass production, do a trial pressing and sintering using mould,

3rd, Check the appearances and the sizes of the samples with micrometer, projectors etc.

Test process of high lifetime Cemented Carbide button stud pins HPGR for breaking stones formations

1st,Mass production, press the raw materials to shape blanks,

Notes: all carbide stud pins blanks must be passed by semi finished inspection

2nd,Sinter blanks to finish (HIP) and finished products inspection,

Notes:10 sets of vacuum sintering furnace and 2set of HIP in the factory ensure the best quality and production capacity.

3rd,Cleaning/tumbling to make the carbide stud pins clean and nice surface.
