Buyer Questions
Which blade is used for recycling, granulator and shredder knives?
The candidate depends on material construction, cutting process, machine arrangement, dimensions, speed and required edge quality. The applications above narrow the review but do not replace machine-specific confirmation.
What information is needed for a blade review?
Send the material structure and thickness, blade or machine drawing, mounting dimensions, cutting speed, operating temperature, current problem and required cut quality.
Can MEIRENTE manufacture a custom blade?
Custom industrial knives can be reviewed from a usable drawing, sample or machine-specific dimensions. Final specifications are confirmed before production.
