Description of the case

The shredder knives are for a prototype shredder machine for plastic. Initially the engineers tried knives from material 65G which lasted only few hours during testing. Moreover the quality of cutting was extremely poor. Now with the Hardox 450 knives the shredding tests were successful - no problems and good quality of the plastic cut pieces. We are looking forward to measure the durability of the knives.
