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.
