3. Manufacturing Process:
- Powder Preparation: Raw ferrite materials are mixed, calcined, and milled to micron-level powders.
- Pressing & Molding: Isostatic or dry pressing using wedge-shaped molds for precise geometry.
- Sintering: High-temperature sintering at 1200–1300°C for densification and grain bonding.
- Grinding & Finishing: Machining for dimensional accuracy and smooth wedge mating surfaces.
4. Surface Treatment & Coating Technology:
Ferrite magnets are inherently resistant to corrosion and oxidation, thus typically do not require surface coatings. For added protection or marking, the following may apply:
- Epoxy Resin Coating (optional): Adds wear and environmental resistance.
- Laser Engraving: For polarity, orientation or batch coding.
- Anti-rust Oil Treatment: Light oil film for storage under high humidity.
5. Appearance & Dimensional Inspection Standards:
- Manual inspection with calipers and angle gauges
- Visual inspection under standard lighting (800–1200 lux)
- 2D imaging system for irregular geometry accuracy
- Magnetic field and polarity verification
- Custom fixture-based slot and wedge matching checks
6. Packaging Process & Instructions:
- Sorting and inspection before packaging
- Mated wedge pairs aligned and packed to preserve orientation
- Vacuum sealed or shrink-wrapped for moisture control
- Internal partitions or foam to prevent chipping
- Cartons labeled with grade, quantity, and orientation
7. Application Fields:
- Brushless DC Motors (BLDC): Segment rotor rings for consistent torque and magnetic balance
- Generator Rotors: Wedge layout for compact flux path control
- Magnetic Couplings: Torque transmission in chemical pumps
- Household Appliances: Motors in air conditioners, washing machines, etc.
- Automotive: Power steering, windshield motors, seat actuators
- Fan Blowers and HVAC Systems: Cost-effective and stable rotor design
8. Usage Precautions:
- Handle with care to avoid chipping; ferrite is brittle
- Avoid sudden temperature shocks post-sintering
- Store in dry environments away from alkaline substances
- Confirm proper polarity and wedge orientation before assembly
