Production and test of TC carbide cross tips four heads
1, After the order is confirmed,TC carbide cross tips 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 the 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
TC carbide cross tips must be passed by semi finished inspection.
4, Then sinter blanks to finish (HIP) and finished products
inspection, we have 10 sets of vacuum sintering furnace and 2 sets
of HIP in the factory ensure the best quality and production
capacity.
