MASTERCUT also offers very sharp film cutting granulator blades made of high quality hardened and tempered tool steel.  They granulate soft energy-absorbing materials such as polyolefin films more efficiently.

Our customers have asked:

What is the right material for granulator blades that can crush at least 100 tons of PET bottles before sharpening?

We have several customers producing Flake from PET Milk bottles using our blades. Typical performance with a good European machine is 175 tons per week between regrinds. We make these Granulator blades from HCHC vacuum Hardened and double press tempered to Rc 55/57. Please notice, the correct cutting angle geometries also play important role.
