SHJ has provided machine knives for plastic industry for 16 years. Knives for the plastics industry include shredder knives, pelletizer knives and granulator knives.

Material selection: Cr12MoV, D2 and tungsten carbide

At first, customers often ask and purchase D2 plastic cutting knives, but in fact, Cr12MoV material is a good choice, except that the latter vanadium content is not the same as the former, the two materials are similar, the effect is basically the same, but the cost of Cr12MoV is relatively lower. Therefore, based on experience, we are willing to recommend Cr12MoV, this suitable but not expensive material to help customers save costs.
