 Production process of cemented carbide studs                                                   

1, Soon after the order is confirmed, tungsten carbide studs 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 studs 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 studs blanks must be passed by semi finished inspection,
