Frequently Asked Questions (FAQs)

Find expert answers to common questions about our Custom Industrial Plastic Crusher Blades for PE, PP, HIPS, PA, PET, PC, and PVC.

To provide an accurate quote for custom plastic crusher blades, we typically need: 1) Technical Drawings (CAD files, PDF, or detailed sketches with all dimensions and tolerances). 2) Machine Model Information (brand and model of your granulator, shredder, or crusher). 3) Material Specification (the primary plastic types you process, e.g., PP, PVC pipes, PET bottles). 4) Quantity Required. 5) Preferred Material Grade (if known, e.g., D2, HSS). If you have a sample of the old blade, that is also extremely helpful for reverse engineering. With this information, we can engineer the optimal custom industrial blade solution for you.
While a formal machinery test report is not provided for standard orders, we employ a rigorous multi-stage quality assurance process. This includes: 1) Strict Material Certification: Sourcing from certified steel suppliers. 2) Precision CNC Machining: Using advanced equipment for dimensional accuracy. 3) Controlled Heat Treatment: Ensuring correct hardness and toughness. 4) Final Dimensional Inspection: Verifying all specs against your drawing with precision tools. 5) Video Outgoing-Inspection: We provide a video showing the final blades, their measurements, and the packing process, offering visual proof of quality and compliance. Additionally, our 3-month warranty provides assurance against manufacturing defects.
Yes, material selection is critical for optimal blade life and performance. For PA (Nylon), which can be abrasive, we recommend steels with high wear resistance. For PC (Polycarbonate), a tough material, blades need a good balance of hardness and toughness to resist chipping. For PVC, especially rigid pipes, impact resistance is key, and sometimes stainless grades are considered if there are corrosion concerns from additives. We provide material consulting as part of our customization service. Based on your primary material (e.g., PET crusher blades for bottles or PVC shredder blades for pipes), we recommend the most suitable steel grade and heat treatment to maximize your granulator knife lifespan.
For a custom order of 1-50 pieces, our standard lead time is 15 days, starting from final drawing approval and order confirmation. This period covers material procurement, precision manufacturing, heat treatment, quality inspection, and packing. While our schedule is optimized for efficiency, expedited production may be possible for urgent needs, depending on current factory capacity. We recommend contacting our sales team directly to discuss expedited options, potential additional costs, and to get a confirmed timeline for your specific plastic recycling machine blades requirement.
Absolutely. Providing custom blades for obsolete or uncommon crusher models is a core strength of our service. Even if original parts are no longer available, we can manufacture perfect replacements. The process is straightforward: you can send us the old blade as a sample for precise reverse engineering, or provide detailed measurements and drawings. Our engineering team will then produce new industrial cutter blades that match or even exceed the original specifications, often with improved material choices. This service is invaluable for extending the life of older but still functional plastic granulators and shredders.
Our 3-month warranty provides coverage for defects in material and workmanship under normal use. It includes: 1) Material Flaws (e.g., cracks originating from the steel itself). 2) Manufacturing Defects (e.g., significant dimensional inaccuracies not per drawing, improper heat treatment leading to premature softening or brittleness). The warranty does not cover: 1) Normal Wear and Tear from use. 2) Damage from improper installation, misuse, or operation outside designed parameters. 3) Failure due to processing of non-plastic materials (e.g., metals, stones) or materials significantly harder than those specified (e.g., glass-filled plastics if not agreed upon).
Yes, PVC pipe shredder blades face unique challenges and require specific design considerations: 1) High Impact Resistance: PVC pipes are hollow and can cause significant impact loads; blades need high toughness to avoid chipping. 2) Corrosion Resistance: Some PVC formulations contain additives that can be corrosive; selecting appropriate steel is important. 3) Cutting GeometryHeat Management: PVC can soften and gum up blades if heat builds up; proper clearance and sharpness are vital. We tailor our custom industrial blades specifically for these factors to ensure efficient and reliable PVC pipe size reduction.
Our video outgoing-inspection is a key quality assurance tool, especially for international customers who cannot visit our factory. Before shipment, we create a dedicated video for your order. This video typically shows: 1) Final Product Showcase: Clear shots of all finished blades. 2) Dimensional Verification: Using calipers or other tools to measure critical dimensions against your specifications. 3) Surface & Edge Inspection: Close-ups showing the finish and sharpness. 4) Packing Process: Showing the blades being securely packed into the shipping carton. This video file is then sent to you via email or a file-sharing link, providing visual confirmation that your custom plastic crusher blades have been manufactured and packed correctly before they leave our facility.
