   • Shafts: Often made from high-tensile strength alloy steel, precision ground to ensure minimal run-out and optimal bearing fit.
   • Housing/Frame: Constructed from heavy-gauge structural steel (e.g., Q235B or SS400 equivalent), laser-cut for precision, and then welded.
   • Motor & Gearbox: Sourced from reputable manufacturers adhering to international standards (e.g., IEC standards for motors) for efficiency and reliability.
3. Core Component Manufacturing (Casting, Forging, CNC Machining):
   • Forging: Shredder blades are often forged to refine the grain structure of the steel, improving its strength and resistance to impact.
   • CNC Machining: Following forging or initial casting, critical components like blades, shafts, and bearing housings undergo precise CNC (Computer Numerical Control) machining. This ensures exact dimensions, tight tolerances, and superior surface finishes, which are vital for smooth operation and component longevity.
   • Heat Treatment: Blades and other wear-prone parts are subjected to a rigorous heat treatment regimen (hardening, tempering, sometimes cryogenic treatment) to achieve optimal hardness (e.g., 58-62 HRC for blades) and toughness, enhancing their lifespan and cutting performance.
4. Fabrication and Welding: The frame and housing components are precisely cut (often using laser or plasma cutters), bent, and then expertly welded together using techniques like MIG (Metal Inert Gas) or TIG (Tungsten Inert Gas) welding. Weld quality is crucial for structural integrity and undergoes visual and sometimes NDT (Non-Destructive Testing) such as ultrasonic or magnetic particle inspection.
5. Assembly: All manufactured components, along with purchased parts (motor, gearbox, bearings, electrical controls), are meticulously assembled. Precision fitting and balancing of rotating components (like the rotor assembly with blades) are critical to minimize vibration and extend bearing life.
6. Quality Control and Testing: Each metal shredder for home use undergoes rigorous testing before shipment. This includes:
   • Dimensional Checks: Ensuring all parts meet specified tolerances.
   • Performance Testing: Running the shredder with various materials (e.g., aluminum cans, thin steel sheets) to verify shredding capacity, output particle size, and overall efficiency.
   • Noise and Vibration Analysis: Measuring operational noise levels to ensure they are within acceptable domestic limits and checking for excessive vibrations.
   • Electrical Safety Checks: Conforming to standards like UL, CE, or country-specific electrical safety regulations.
