2. About pressing:
1).How do Mingri start TC brazed tips production? How do we check?
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. About Furnace:
1).How many furnaces for TC brazed tips production ?
10 sets of vacuum sintering furnace and 1set of HIP
10 sets of sintering furnace and one set of HIP in the factory ensure the best quality and production capacity.
4. About cleaning/tumbling :
1). cleaning/tumbling is to make the TC brazed tips look more beautiful.
2).The TC brazed tips can be ground according to customers’ order to a tolerance of +/-0.05
5 About laboratory:
1.How do you produce samples of TC brazed tips for control?
We sample each batch RTP into pressing and sintering, only when certificated by the laboratory, the RTP can be put into mass production.
