Frequently Asked Questions (FAQs)

Get expert answers to the most common questions about Threaded Hole Single Shaft Shredder Knives for plastic recycling applications.

The threaded hole design offers several key advantages for single shaft shredder blades: 1) Enhanced Safety: The blade is directly threaded onto the shaft or mounting studs, eliminating the risk of bolts loosening and blades flying off during operation—a critical safety improvement. 2) Cleaner Cutting Surface: Without protruding bolt heads, the cutting surface remains smooth, reducing material hang-up and improving cutting efficiency. 3) Simplified Installation & Maintenance: Direct threading makes blade changes faster and easier. 4) Improved Stability: The threaded connection provides superior vibration resistance and maintains precise blade alignment, crucial for consistent plastic recycling output and extended machine life.
The choice depends on your specific plastic recycling application: 5WSiCr (Spring Steel) offers excellent toughness and good wear resistance at a competitive price, ideal for general-purpose shredding of most plastics like PET, HDPE, and PP. H13H (Hot Work Tool Steel) provides superior thermal fatigue resistance, making it perfect for applications with continuous operation or materials that generate significant heat (like engineering plastics), preventing heat-related cracking. DC53 (High Carbon High Chromium Steel) delivers the highest wear resistance and hardness, best for extremely abrasive materials like glass-filled plastics, fiber-reinforced polymers, or operations where maximum edge life between sharpenings is critical. Our experts can help select the optimal material for your waste recycling machine.
For an order of 1000 pieces, which falls well within our 1-5000 pieces standard production range, our lead time is 31 days after order confirmation and deposit receipt. This efficient timeline is maintained through our optimized production流程 for threaded hole blades. It includes material procurement, precision CNC machining of both the blade profile and threaded holes, specialized heat treatment based on the selected steel grade, final grinding and finishing, comprehensive quality inspection (including thread gauge testing), and secure packaging. For orders exceeding 5000 pieces, we negotiate a custom production schedule to meet your volume requirements while maintaining our high-quality standards.
Our 1.5-year warranty is one of the most comprehensive in the industry for shredder blades. It covers manufacturing defects in materials and workmanship under normal operating conditions for plastic recycling applications. The warranty period begins from the date of delivery. If a defect occurs during this period, we will replace the defective blades at no cost (subject to verification). This extended warranty reflects our confidence in the quality of our materials, heat treatment processes, and precision manufacturing. It's important to note that the warranty does not cover normal wear and tear, damage from improper installation, operation outside design parameters (e.g., shredding unintended materials), or lack of proper maintenance. Always refer to the specific warranty terms provided with your order.
Absolutely. As part of our comprehensive customization service, we can manufacture threaded hole shredder blades with either metric (ISO) or imperial (UNC/UNF) threads, or any other specific thread standard you require. We need precise specifications including thread diameter, pitch (threads per inch or millimeter pitch), thread class (tolerance), and thread depth. We use precision tapping equipment and thread gauges to ensure perfect thread accuracy and fit. This flexibility is essential for customers worldwide who operate shredders from different manufacturers or regions. Providing either the original blade sample or detailed engineering drawings with thread specifications ensures we produce blades that fit your waste recycling machine perfectly.
"High-Accuracy" refers to the exceptional dimensional precision and consistency we achieve in manufacturing our threaded hole shredder knives. This encompasses: 1) Dimensional Tolerance: Blades are produced with tight tolerances (typically within ±0.05mm to ±0.1mm) on critical dimensions like width, thickness, and hole positions, ensuring perfect fit and balance on the rotor. 2) Thread Precision: Threaded holes are machined to exact specifications with proper alignment, preventing cross-threading during installation. 3) Cutting Edge Geometry: The cutting edge angle and profile are consistently replicated across all blades in a set. This high accuracy results in balanced rotation, reduced vibration, uniform cutting performance, consistent particle size output, and extended bearing life in your plastic shredding equipment.
Given their 15kg weight and sharp edges, proper handling and storage of threaded hole shredder blades is crucial for safety and blade preservation: 1) Use Proper Lifting Equipment: Always use mechanical aids (hoists, forklifts) or get assistance when moving blades; avoid manual lifting to prevent injury. 2) Edge Protection: Use protective caps or covers on the cutting edges during handling and storage to prevent nicks and protect personnel. 3) Horizontal Storage: Store blades flat on a stable, level surface; do not stand them on edge where they could fall. 4) Climate Control: Keep in a dry environment to prevent rust, especially on the precision threads. 5) Thread Protection: Consider using thread protectors or lightly coating threads with anti-seize compound for long-term storage to prevent corrosion and ensure easy installation later.
Yes, absolutely. Our Minimum Order Quantity (MOQ) of 1 set is a significant advantage, especially for small to medium recycling operations, maintenance departments, or for testing purposes. You can order exactly the number of blades you need for a complete rotor assembly (a "set"), whether that's 10, 20, or any other quantity required to fill your machine's rotor. This low MOQ policy eliminates the need to purchase large quantities upfront, reduces inventory costs, and makes it feasible to keep spare blades on hand for timely maintenance. It demonstrates our commitment to serving customers of all sizes in the plastic recycling industry. Even for a single set, we provide the same comprehensive quality assurance including machinery test reports and video inspection.
