Accurate CNC Grinding: All mounting surfaces and cutting edges are CNC finished within 0.01mm tolerance. Perfect rotor and stator parallelism keeps consistent blade gaps, delivering clean, dust-free granulation results.
High-Grade Steel Material: Blades are made of vacuum heat-treated tool steel. Standard SKD11 (1.2379) steel provides great wear resistance for rigid plastic recycling. Upgraded DC53 steel offers much better impact toughness, effectively avoiding blade chipping when cutting high-fiber abrasive materials.
No Overheat Damage: Targeted coolant cooling during high-speed grinding protects the steel internal structure. Blades maintain stable working hardness up to HRC 55-62 for long service life.

Go with 9CrSi for regular recycled plastics.
Select SKD11 plastic crusher blade for standard hard plastic processing.
Use DC53 when handling heavy loads, thick materials and fiber-reinforced plastics.
Dull blades will slow down your production and cause unnecessary downtime. Switch to our durable plastic granulator blades and crusher knives for cleaner cuts, higher productivity and lower running costs. Feel free to contact us for custom solutions.
Using standard blades for hard or fiber-reinforced plastics: Standard blades lack sufficient hardness and wear resistance for these materials. They wear out quickly, crack easily and require frequent replacement.
Using overly hard blades for soft plastics: Hard blades do not have enough toughness for soft plastic processing. They often cause material jams, interrupt continuous operation and may even damage the shredder.
Hard plastics: Use SKD-11 blades. Featuring high hardness and reliable wear resistance, they handle hard plastic cutting and shredding steadily.
Soft plastics: Use 9CrSi blades. Their balanced hardness and toughness prevent material jams and ensure smooth shredding operation.
Fiber-reinforced plastics, thick materials & mixed materials: Use DC53 blades. This steel grade withstands complex stress, strong impact and heavy wear, making it ideal for tough, thick and fiber-containing materials.
Entry-level & general use: 9CrSi is the best choice for cost-sensitive general scenarios. It is affordable and stable for most ordinary recycled plastics with no special processing requirements, covering daily conventional shredding work.
Professional high-efficiency use: SKD-11 is the standard blade material for mid-to-high-end shredders. It delivers a perfect balance of strength, durability and cost, offering excellent long-term cost performance for high-intensity continuous work.
High-wear & heavy-duty use: If budget allows, choose DC53 for processing high-fiber materials and thick workpieces. Its superior stress resistance and wear resistance significantly extend blade service life under harsh working conditions.
