Our company can customize all kinds of ring die with different hole size, based on customers’ demand, or detailed drawing.
Smooth finish of the hole inner-wall can reduce the drag when material enters into the hole, which can help increase the production, while well-distributed feed inlet can ensure the uniformity.
The hardness for 46Cr13 ring die is 52-56, and difference between each part is less than 2.
After heating(under 1050℃) and refrigeration and quenching, the ring die comes into some deformation infinitesimally, 0.3-1mm, and after being processed by grinder, the deformation can decrease to 0.05-0.15mm.
