Production and test:
1)Carbide Buttons will start to prepare the powder as per the customer’s
requirement with our wet-grinding machine
2) Before mass production, we need to do a trial pressing and sintering, and we check the
appearances and the sizes of the samples with a micrometer 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
carbide tips must be passed by semi-finished inspection.
4) sinter blanks to finish (HIP) and finished products inspection
to ensure the best quality and production capacity.
