1. Flat top, protect the cemented carbide pins from being destroyed by stress concentration.

2. Round edges, protect the cemented carbide pins being damaged during production, transportation, installment and using.

3. HIP sintering ensure good compactness and high toughness for the products.

4. Special technology to eliminate the surface stress after surface grinding, and increase the surface hardness at the same time.

5. Grease used on surface of the products to avoid oxidization.

Grades below are exclusive grade we developed for rolling machine. Good wear resistance and high strength are suitable for metal smashing with high working efficiency. Lifetime of cemented carbide pins over 8000-10000 hrs.

Dimensions can be done by client's drawing.

 If rolling machine uses cemented carbide pins, it gets high density,high strength and good impacting property. Lifetime of cemented carbide pins is over 10 times more than surfacing material.

1, Soon after the order is confirmed, cemented carbide pins products 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 cemented carbide pins 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 cemented carbide pins blanks 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.

5, 1). cleaning/tumbling is to make the cemented carbide pins look more beautiful.
     2).The cemented carbide pins can be ground according to customers’ order tolerance requirement

step 1, wrapped cemented carbide pins in paper to avoid cemented carbide pins to broke
