• Core materials: High-hardness, high-toughness alloy tool steels such as D2, H13, and Cr12MoV
• Heat treatment process: Vacuum quenching + deep cryogenic treatment to improve hardness uniformity and impact resistance
• Surface strengthening: The blade edge can be coated with tungsten carbide (WC) or titanium nitride (TN) coating to extend service life
• Precision machining: CNC machining ensures precise installation dimensions, and dynamic balancing tests guarantee smooth operation
• Plastic Recycling: Shredding of plastic barrels, pipes, thick-walled products, and injection molding waste
• Tire Processing: Shredding and volume reduction of car and truck tires
• Metal Recycling: Light metal sheets, aluminum profiles, and scrap metal
• Electronic Waste: Shredding and sorting of circuit boards, casings, and cables
• Wood and Paper: Waste wood, paper mill waste, and packaging materials
• Industrial Waste: Rubber products, composite materials, and insulation materials
1. Long lifespan: Special steel materials and surface treatment technology significantly extend the replacement cycle.
2. High efficiency and energy saving: Optimized blade design reduces equipment load and saves power consumption.
3. Stable operation: High-strength design ensures continuous full-load operation without blade breakage or deformation.
4. Convenient maintenance: Supports single-blade replacement, reducing downtime and maintenance costs.
5. Flexible customization: Blade type, hole position, and thickness can be customized according to material characteristics and equipment model.
• We provide selection guidance and crushing solution optimization.

Fine Shredding · Suitable for Pre-treatment in Plastic Recycling and Granulation
Plastic shredder blades (also known as crusher blades or granulator blades) are key tools in processes such as plastic recycling, injection molding scrap recovery, and film shredding. We offer a variety of blade types and materials, suitable for the efficient shredding of various thermoplastics such as PE, PP, PET, ABS, and PC.
Blade Types | Blade design features: | Applicable Plastic Types: | Crushing particle size: |
|---|---|---|---|
Claw-shaped blade | Multi-claw shearing structure for strong gripping force | Rigid plastics, thick-walled parts, profiles | Medium-coarse crushing (10-30mm) |
Flat blade | Flat blade design for high cutting efficiency | Films, sheets, thin-walled injection molded parts | Medium-fine crushing (5-15mm) |
Stepped blade | Stepped blade edge for progressive crushing | Tough plastics, fiber-reinforced materials | Uniformly crushed material (8-20mm) |
Double-edged blade | Usable on both sides, doubling the lifespan | General plastic recycling, mixed material processing | Adjustable crushing |
Material: | Hardness (HRC) | Features: | Applicable Scenarios: |
|---|---|---|---|
SKD-11 | 58-60 | High wear resistance, highly versatile | General plastic crushing, PP/PE recycling |
D2 | 58-62 | High hardness, excellent wear resistance | Reinforced plastics, recycled materials containing impurities |
HSS (High-speed steel) | 60-64 | High temperature resistance, suitable for continuous high-speed grinding | PET bottle flakes, engineering plastics |
Carbide-tipped | 62+ | Extremely wear-resistant, exceptionally long lifespan | Plastics with high glass fiber content, long-running production lines |
• Plastic recycling and granulation: Crushing after washing, agglomeration crushing, and fine crushing pretreatment
• Injection molding and blow molding: On-site recycling of sprues, defective products, and scraps
• Film and flexible packaging: Crushing of PE film, PP woven bags, and composite films
• Bottle flakes and rigid plastics: Crushing of PET bottles, HDPE containers, and PVC profiles
• Engineering plastics: Crushing and recycling of PA, PC, ABS, etc.
1. High crushing efficiency: Optimized cutting angle improves output and reduces energy consumption.
2. Uniform output: Controlled particle size facilitates subsequent cleaning, sorting, and granulation.
3. Strong impact resistance: Tough base material and reinforced treatment prevent chipping and cracking.
4. Flexible adaptation: Customizable installation dimensions to suit various equipment brands (e.g., Japanese, German, and domestic models).
5. Low maintenance costs: Supports regrinding and refurbishment, significantly reducing long-term tool investment.
Q: Are the shredding blades prone to jamming or material entanglement?
A: We reduce the risk of entanglement by optimizing the blade shape and discharge angle design; we can also recommend the most suitable blade type based on your material characteristics.
Q: How long does a set of blades typically last?
A: This depends on the type of plastic, purity, shredding particle size, and equipment condition. Generally, for pure material shredding, they can be used continuously for hundreds of hours. We provide wear assessment and lifespan prediction services.
Q: Do you provide matching sets of rotating and stationary blades?
A: We provide complete sets of rotating blades, stationary blades, spacers, and screws to ensure proper installation and stable operation.
Please provide the following information, and we will match or design the most suitable shredding blades for you:
1. Shredder brand, model, and blade disc size
2. Main types and forms of plastics to be shredded (blocks/films/flakes, etc.) and target particle size
3. Current production capacity and power consumption
4. Equipment operating time and maintenance cycle
