BladeRunner extended wear life blades are premium tungsten carbide
bits designed to extend the wear life of the edge, reducing the
need for blade changes.
These high-strength tungsten carbide bits will bolt to virtually
any snow plow or motor grader and are to be used where the customer
requires longer blade life.
Production Process
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
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.
