Selecting blades for a plastic shredder should begin with the waste and the installed rotor. Film, fibers and rigid pieces arrive at the cutting area in different ways, even when they belong to the same polymer.
The rotor as part of the application
WEIMA presents different rotor and cutting technologies, including combination of V configurations and blade systems. These options illustrate the importance of adapting the set to the material; They are not a universal recommendation for any model or lot.
Describe the input flow
Record known polymer, humidity, format and contamination. Look to see if the problem is tangling, slipping, intermittent feeding, or wear. A failure associated with the pusher or the entry size is not necessarily resolved by replacing the blade with one that is harder.
Check compatibility and results
Identify machine, rotor and tool reference. Compare dimensions, anchors and support surfaces with reliable documentation. After an authorized change, measure useful production and output material characteristics with equivalent batches. Keep a history of sharpenings and game positions. The WEIMA WLK blades in the catalog that illustrate this guide should not be extrapolated to all the brand’s machines.
Frequently asked question
Does the same blade work for film and rigid plastic?
The answer depends on the equipment, rotor, and approved application. It must be confirmed before assembly.
