Granulator Knives for Plastic Recycling
Granulator knives are the consumable heart of every plastic recycling line. Ours are cut from SKD11, D2 or HSS alloy steel, vacuum heat treated to HRC 55-62 and CNC ground, so the crushing chamber keeps producing even, clean-cut granules hour after hour.
The difference shows up in your operating cost: a dense, refined steel structure resists abrasion from continuous crushing, while a precisely finished edge cuts without smearing or sticking – fewer knife changes per tonne and steadier output quality.
Send us your machine model, a drawing or a worn-out sample and we will produce rotor and stator knives to the exact length, thickness, hole pitch and cutting angle your granulator needs.

Key Advantages
01Select the Right Steel
SKD11, D2, HSS or a custom alloy – vacuum heat treated so the hardness profile matches your material and duty cycle.
02Even, Clean Crushing
A CNC-ground edge cuts granules to uniform size without smearing, sticking or fines, keeping downstream processes happy.
03Slow, Predictable Wear
Dense refined steel structure resists abrasion during continuous crushing, lowering replacement cost per tonne.
04Fits Your Machine
Blade length, thickness, hole spacing and mounting dimensions are produced to order for any granulator brand.
05Resists Cracking
High overall rigidity keeps the knife from chipping or deforming when hard contaminants pass through the chamber.
06OEM & ODM Support
We design and manufacture knives from technical requirements, drawings or samples – one supplier, complete solution.

FAQ
Can you match knives to my granulator model?
Yes – we work from your machine model, a technical drawing or a used sample to produce an exact-fit knife.
Which steel should I choose?
SKD11 and D2 suit most plastic crushing; HSS adds hardness for abrasive or high-throughput lines. We advise based on your material.
Can I test a sample first?
Of course – standard and custom samples are available so you can check the crushing result on your own machine.
What is the usual lead time?
Stock sizes ship in 3-7 days; custom knives take 7-15 days depending on design and quantity.
