To ensure the quality and the requirements of the drawings can be met before mass production
1st:, Start to prepare the RTP powder as per customer's requirement with our wet-grinding machine
2nd, Before mass production, do a trial pressing and sintering using mould,
3rd, Check the appearances and the sizes of the samples with micrometer, projectors etc.
Test process of High density hard alloy wear resistant cemented tungsten carbide plates
1st,Mass production,press the raw materials to shape blanks,
Notes: all carbide plates blanks must be passed by semi finished inspection
2nd,Sinter blanks to finish (HIP) and finished products inspection,
Notes:10 sets of vacuum sintering furnace and 2set of HIP in the factory ensure the best quality and production capacity.
3rd,Cleaning/tumbling to make the carbide plate clean and nice surface
