Production Process of Good abrasion resistance for Raw materials Tungsten Carbide mining insert tips bits for mine drilling
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 Good abrasion resistance for Raw materials Tungsten Carbide mining insert tips bits for mine drilling
1st,Mass production, press the raw materials to shape blanks,
Notes: all carbide stud pins 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 stud pins clean and nice surface.
Packing of Good abrasion resistance for Raw materials Tungsten Carbide mining insert tips bits for mine drilling
step 1, wrapped carbide stud pinsr in paper to avoid carbide stud pins be broken
step 2, put the carbide stud pins in inner small carton box
