Frequently Asked Questions (FAQs)

Find expert answers to common questions about High-Quality 9CrSi & D2 Plastic Crusher Blades for efficient plastic recycling.

9CrSi tool steel offers several key advantages for plastic crusher blades: 1) Excellent Hardenability: It can achieve a uniform hardness of 58-60 HRC throughout the blade, ensuring consistent cutting performance. 2) Good Wear Resistance: The chromium and silicon content provide solid resistance to abrasion from plastic materials. 3) High Toughness: It maintains good impact resistance, reducing the risk of chipping when processing hard plastic lumps or encountering occasional contaminants. 4) Cost-Effectiveness: Compared to some high-alloy steels, 9CrSi offers a favorable balance of performance and price, making it an excellent choice for cost-sensitive plastic recycling operations.
Nitriding is a thermochemical surface hardening process that diffuses nitrogen into the surface of the steel. For plastic crusher blades, this treatment provides significant benefits: 1) Increased Surface Hardness: Creates an extremely hard surface layer (often exceeding 1000 HV) while maintaining a tough core, dramatically improving wear resistance against abrasive plastics. 2) Enhanced Fatigue Strength: Improves resistance to surface cracking under cyclic loading. 3) Improved Corrosion Resistance: Offers better protection against moisture and acidic residues sometimes present in plastic waste. 4) Reduced Friction: The hard, smooth surface lowers the coefficient of friction, allowing plastic material to flow more easily and reducing heat buildup. This combination can extend blade life by 30-100% in many plastic recycling applications.
Service life varies based on the specific plastic material processed, machine settings, and maintenance practices. For processing common plastics like PET, HDPE, or PP without heavy contamination, our 9CrSi/D2 blades with nitrided treatment typically last between 300 to 600 operating hours before requiring sharpening. For more abrasive materials (glass-filled plastics, heavily printed film), life may range from 150 to 300 hours. Proper blade gap adjustment, regular cleaning to prevent material buildup, and avoiding metal contaminants are key to maximizing lifespan. The nitrided surface significantly extends this range compared to non-treated blades.
Yes, our minimum order quantity (MOQ) is truly 1 piece, which is exceptionally low for customized industrial blades. This allows for prototype development, testing, or small-scale replacement needs. Customization options starting from 1 piece include: Customized Logo (laser marking your brand), Customized Packaging (tailored to your requirements), Graphic Customization (specific markings or identifiers), Function Design (modifying the blade for specific performance characteristics), and Turnkey Design (complete blade design from scratch based on your specifications). This flexibility makes our service ideal for startups, R&D projects, or operations with unique, low-volume needs.
Choose D2 tool steel when processing highly abrasive plastic materials or when maximum wear resistance is the priority. D2 has higher chromium and carbon content, giving it superior wear resistance and the ability to hold a sharp edge longer in continuous operation with abrasive feedstocks (like fiberglass-reinforced plastics or materials with mineral fillers). Choose 9CrSi steel for general-purpose plastic recycling applications where a balance of toughness, wear resistance, and cost-effectiveness is needed. 9CrSi typically offers better toughness (impact resistance) at a lower cost, making it suitable for mixed or less abrasive plastic streams. Our engineers can recommend the best material based on your specific plastic waste composition.
Our video outgoing-inspection provides transparent visual confirmation of your order's quality. The video typically includes: 1) Order Identification: Showing your order number and the batch of blades. 2) Visual Inspection: Close-up examination of blade surfaces, edges, and any custom markings or logos. 3) Dimensional Verification: Using calibrated measuring tools (calipers, micrometers) to check critical dimensions against your specifications. 4) Hardness Spot Check: Demonstration of hardness testing to confirm the 58-60 HRC range. 5) Surface Treatment Verification: Visual confirmation of the nitrided surface finish. 6) Packaging Process: Showing the blades being securely placed in the wooden box. This process ensures you receive exactly what you ordered before shipment.
Our 6-month warranty covers defects in materials and workmanship under normal operating conditions for plastic recycling applications. Specifically, it covers issues such as: premature cracking or breaking not caused by impact with metal or other foreign objects; failure of the nitrided surface treatment under normal use; or manufacturing defects that prevent proper installation or function. The warranty period begins from the date of delivery. To make a warranty claim, please provide photos/videos of the issue, your order details, and a description of the operating conditions. This warranty provides assurance of our commitment to quality in manufacturing plastic recycling equipment components.
The 25-day lead time for orders of 1-10 pieces is our standard production schedule from order confirmation and deposit receipt. This period includes: material procurement, CNC machining, heat treatment to achieve 58-60 HRC, nitriding surface treatment, precision grinding and sharpening, quality inspection, and final packaging. For urgent requirements, expedited production may be possible for an additional fee, depending on current factory capacity and material availability.
