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 cutter blade 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 cutter blanks must be passed by semi finished inspection,

4, Then sinter blanks to finish (HIP) and finished products inspection, we have10 sets of vacuum sintering furnace and 2set of HIP in the factory ensure the best quality and production capacity.

5, 1). cleaning/tumbling is to make the tungsten carbide cutter look more beautiful.
    2).The tungsten carbide cutter can be ground according to customers’ order to a tolerance of +/-0.05
