The Importance of Shredder Blades
Think of shredder blades as the teeth of your recycling operation—they need to be sharp, tough, and perfectly suited to the task, whether tearing through scrap metal or rigid plastics. At Rumtoo, we craft our blades from premium alloy steels designed to withstand the toughest industrial demands. Choosing the right blade thickness and quantity isn’t just a technical detail; it directly impacts your output granularity and production efficiency. With blades accounting for roughly 20% of a shredder’s cost, understanding their manufacturing and selection is the key to balancing performance with cost-efficiency. Here is how we ensure you get the best edge for your business.
Shredder Blade Processing: Standards and Procedures
Shredder blade manufacturing should strictly adhere to specific processes and standards to ensure longevity and effectiveness. Here’s a detailed look at the steps involved:
1. Material Selection: We rigorously select premium steels like Cr12MoV and Japanese SKD11, ensuring exceptional durability and wear resistance.
2. Cutting & Forging: We use precision laser cutting for accuracy, followed by forging where materials are inspected to eliminate any defects.
3. Tempering: This essential heat treatment prepares the blade for shaping, balancing hardness with toughness.
4. Machining: We machine the blade to remove impurities and ensure a perfectly flat, uniform surface.
5. Heat Treatment: High-temperature heating followed by rapid cooling locks in the blade’s mechanical properties.
6. Grinding: We grind away surface impurities to prepare the blade for final detailing.
7. Wire Cutting & Fine Grinding: Finally, we refine the edges and test hardness to guarantee the blade meets strict quality standards.
Choosing the Right Blade Material
Your choice of material dictates performance. We recommend high-carbon, high-chromium steels like Cr12MoV, D2, and DC53 for their superior hardness and wear resistance. These materials are engineered to handle tough feedstock without frequent replacement.
