Sintering
HIP.
The advanced computer-controlled HIP furnaces are applied to provide more pressure during the sintering process in order to get denser structure.
Powder
Excellent.
Thanks to our deep cooperation with Germany H.C.Starck, we use the best powder for carbide rod in the world for all our standard grades for carbide rod manufacturing.
Cooling
Internal.
The internal cooling hole can provide much more efficient chip evacuation and deeper hole making capabilities. We supply not only straight coolant but also spiral coolant carbide rod.
OEM Custom Service
We can develop grades as per your requirement and make the same shape as your drawing. Laser marking and neutral package are also available for your benefits.
