Each blade undergoes a rigorous heat treatment process to achieve an optimal hardness of HRC 56 ~ 58, providing the perfect balance between edge retention and impact resistance for demanding wood and plastic processing. We maintain a precise dimension tolerance of ±0.10 mm and a superior surface roughness of Ra 0.2 mm, ensuring perfect fit, smooth operation, and consistent cutting performance in your chipper or pulverizer.

Key Features & Operational Benefits

Engineered for longevity and efficiency, our blades offer significant advantages. Their primary key selling points are high-accuracy and a superior cutting edge. The double-edge design allows for extended service life through rotation or reversal when one edge dulls, effectively doubling the time between maintenance. The combination of high-quality raw materials and expert heat treatment ensures blades resist abrasion from fibrous wood and abrasive PVC fillers. This translates directly to reduced frequency of blade changes, lower maintenance costs, and sustained high-quality output, maximizing the productivity of your wood chipping or plastic pulverizing operation.

Frequently Asked Questions (FAQs)

Find expert answers to common questions about Wood Chipper Blades and PVC Pulverizer Knives for industrial recycling.

A typical wood chipper or crusher machine utilizes two main types of blades working in conjunction: Rotating Knives (or rotor blades) and Fixed Blades (or bed knives). The rotating knives are mounted on a high-speed disc or drum and provide the primary cutting action. The fixed blades are stationary and create a cutting surface against which the rotating knives shear the material. This combination ensures efficient chipping or shredding. In PVC pulverizers, similar principles apply, but blade geometry and hardness are optimized for cutting and impacting brittle plastics into fine powder. Proper alignment and sharpness of both blade sets are critical for optimal machine performance and chip quality.
The choice between Tungsten Carbide and Tool Steel depends on the material being processed and operational priorities. Tungsten Carbide offers extreme wear resistance and hardness, making it ideal for processing highly abrasive materials like contaminated wood (with sand, dirt), fiberglass-filled plastics, or continuous high-volume operations. However, it is more brittle and expensive. Tool Steel (HRC 56-58) provides an excellent balance of toughness, impact resistance, and wear resistance at a lower cost, making it suitable for most wood chipping and general PVC pulverizing applications. Choose Tungsten Carbide for maximum life in extreme abrasion; choose Tool Steel for overall durability and cost-effectiveness in standard conditions. We can advise based on your specific wood recycling or plastic processing needs.
A double-edge blade offers a significant practical and economic advantage for wood chipper and crusher operations. Once the primary cutting edge becomes dull from processing abrasive wood fibers, dirt, or bark, the blade can be rotated or flipped to present a fresh, sharp cutting edge. This effectively doubles the service life of the blade between sharpenings or replacements. The benefits are clear: reduced downtime for blade changes, lower spare parts inventory costs (needing fewer blades on hand), and more consistent cutting performance. For businesses focused on efficient wood waste management, this design directly contributes to higher machine availability and lower operating costs.
The ±0.10 mm dimension tolerance is a critical indicator of manufacturing precision and high-accuracy. In the context of wood chipper blades and PVC pulverizer knives, such tight tolerances ensure that every blade in a set is virtually identical. This precision guarantees: 1) Perfect Fit: Blades install easily and seat correctly in the rotor or fixed housing without forcing or gap issues. 2) Balanced Operation: Consistent weight and dimensions prevent vibration, which protects bearings and extends the overall life of your crusher machine. 3) Uniform Cutting: All blades engage the material equally, producing a consistent chip or powder size and preventing uneven wear. This level of precision is a hallmark of quality blades and is essential for smooth, efficient industrial operation.
Absolutely. We specialize in manufacturing custom blades for both wood chippers and PVC pulverizers. While both applications involve size reduction, the blade design parameters differ. Wood chipper blades typically have a sharper, more aggressive cutting angle to slice through fibrous wood and may be thicker to withstand impacts from knots. PVC pulverizer knives are often designed to fracture brittle plastic through impact and may have different edge geometries. Our engineering team can produce blades optimized for either material or even multi-purpose designs based on your specific machine make, model, and primary feedstock. With our OEM/ODM services, we can replicate or improve upon your existing blades for either application.
Our video outgoing-inspection provides transparent, visual proof of quality for your specific order. The video typically documents: 1) Final Visual Check: Close-up shots of blade edges, surfaces, and markings. 2) Dimensional Verification: Using calibrated tools like calipers to measure critical dimensions against your specifications. 3) Hardness Test Spot Check: Demonstration of hardness testing with a portable durometer if applicable. 4) Packaging Process: Showing the blades being securely packed for shipment. 5) Order Matching: Verifying the quantity and labeling against your order details. This service gives you confidence before shipment that your wood chipper or PVC pulverizer blades meet all agreed-upon standards and are correctly packed for your recycling or manufacturing facility.
While we do not offer a standard time-based warranty, our commitment to quality is robust and multi-layered. We ensure product reliability through: 1) Premium Raw Materials: Using certified tool steel and tungsten carbide. 2) Controlled Heat Treatment: The core component process that determines hardness and toughness. 3) Precision Manufacturing: Adhering to strict tolerances (±0.10mm) and surface finish (Ra 0.2mm). 4) Third-Party Certifications: Our processes are backed by TUV and SGS certifications. 5) Pre-Shipment Verification: Providing machinery test reports and video outgoing-inspection. For specific projects, warranty terms can be discussed. Our focus is on delivering a high-quality product that meets specifications, and our low rate of customer issues reflects this preventative quality-first approach.
For a custom order of 5 sets of wood chipper blades, which falls within our 1-10 pieces standard production range, the lead time is 40 days from order confirmation and payment received. This period encompasses several critical stages: engineering review of your specifications, procurement of the specific tool steel or tungsten carbide, precision machining (including achieving the tight ±0.10mm tolerance), specialized heat treatment to reach HRC 56-58, final grinding and sharpening to create the high-accuracy cutting edge, comprehensive quality inspection, and finally, secure packaging. For larger orders exceeding 10 pieces, we can negotiate a potentially optimized schedule. This timeline allows for thorough manufacturing and ensures you receive precisely crafted blades for your equipment.
