Premium Plastic Crusher & Granulator Blades
The definitive guide to choosing the right blades for your plastic recycling machines. Understand the differences between SKD-11, D2, DC53, and 55SiCr to maximize performance and durability.
Key Blade Materials Compared
Selecting the right material is critical for performance and longevity. Here’s a look at our most popular options.
For Hard Plastics
A top choice for harder plastics like ABS and nylon, offering a great balance of wear resistance and toughness for moderate impact environments.
For High-Wear Applications
Its standout wear resistance makes D2 the champion for processing plastics mixed with abrasive elements like glass fibers, reducing replacement frequency.
For Ultimate Versatility
This jack-of-all-trades material delivers enhanced toughness and superior wear resistance, making it a perfect fit for a variety of challenging materials like PVC and rubber.
For Soft & Flexible Plastics
Ideal for less abrasive soft plastics like PE films, where superior elasticity and impact resistance are key to preventing breakage.
How to Choose the Right Blade
- Consider Your Plastic Type
For hard plastics like ABS, choose a high-hardness material like SKD-11. For abrasive, glass-filled composites, the superior wear resistance of D2 is more suitable. - Balance Budget and Maintenance Costs
For less demanding applications or limited budgets, 55SiCr provides good performance on softer plastics and is the most economical choice. - Factor in Your Workload
For machines operating at high frequency or under heavy loads, DC53 is an excellent choice. Its high toughness resists chipping and breaking in long, continuous operations.
Material Specifications at a Glance
| Material | Key Feature | Ideal Application | Relative Price |
|---|---|---|---|
| DC53 | Balanced Wear & Toughness | Heavy Loads, PVC, Rubber | $$$$ |
| D2 | Extreme Wear Resistance | Glass-Fiber Reinforced Plastics | $$$ |
| SKD-11 | High Hardness & Good Wear | Hard Plastics (ABS, PC, Nylon) | $$ |
| 55SiCr | High Elasticity & Impact Res. | Soft Plastics (PE Film), Shock-Absorbing | $ |
Frequently Asked Questions
What’s the main difference between D2 and SKD-11 steel for blades?
Both are excellent cold-work tool steels. D2 offers slightly better wear resistance, making it ideal for abrasive materials like glass-filled plastic. SKD-11 provides a great balance of hardness and toughness, making it a versatile workhorse for many hard plastics.
Can I use one blade type for all plastics?
While some blades like DC53 are very versatile, using a blade optimized for your specific material (e.g., D2 for abrasives, 55SiCr for soft films) will always result in better performance, longer blade life, and lower operational costs.
How does heat treatment affect blade quality?
Proper heat treatment is critical. Our vacuum heat treatment and triple tempering process ensures that the steel reaches its maximum potential for hardness and toughness, preventing the blade from being too brittle or too soft.
