Production
Product Packaging
1)Inner packing: in paper box.
2)Outer packing: in cartons or plywood case.
Production Flow
1)Carbide Balls 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.
We make carbide rod with double coolant holes, they are used in
high temperature machining for good coolant ways, we also supply
with all types of carbide gundrill tips. For more information, please don't hesitate to contact us.
