Those blades are used in the granulating of rubber and plastics, as well as the cutting of plastic film, which need high accuracy in geometry dimension and angle of cutting edge for fitting with their equipment. For this reason, we use qualified material and good heat treatment, ensuring that the blades have suitable hardness at low residual stress. This not only keeps the strength and sharpness of cutting edge, but also avoids the deformation and break. So far, we have been the main supplier of a famous Japanese producer of plastics granulating machinery.
