Custom high performance stable sintered Neodymium Cylinder Magnet

Custom high performance stable sintered Neodymium Cylinder Magnet

1. Product Overview

Magnets for smart electrical Consumer , Robotics typically use high-performance sintered NdFeB micro magnets. They are characterized by small size, strong magnetic force, and high precision, developed specifically for Vehicle, magnetic charging cases, magnetic ear hooks, and internal audio unit components. These custom heat resistant high magnetic strength stable sintered Neodymium Cylinder Magnets are precisely designed to meet comprehensive requirements for suction, positioning accuracy, electroacoustic performance, and ease of assembly. They support custom shapes (e.g., oval, strip, square, disc) and various coatings (e.g., Ni, epoxy, metallic coatings), and are widely used in consumer-grade smart wearable devices.

3. Manufacturing Process:

This tailor-made high coercive force strong magnetic force stable sintered Neodymium Cylinder Magnet’s manufacturing procedure are as following:

• Sintering Forming: Using Nd, Fe, B and other rare earth elements melted into micron-level powder. Pressed into molds and oriented in a magnetic field to ensure predetermined magnetization direction.
• High Temperature Sintering and Heat Treatment: Sintering in vacuum or inert atmosphere for densification and mechanical strength. Followed by heat treatment to optimize grain boundary structure, improving thermal stability and resistance to demagnetization. 

4. Surface Treatment and Coating Technology:

• Ni Coating: Provides additional chemical resistance and waterproofing, suitable for high humidity environments.
• Ni-Cu-Ni Plating: Standard triple-layer electroplating structure, balances appearance and corrosion resistance. Suitable for general industrial and electronic applications. 

5. Appearance and Dimensional Inspection Standards:

• Manual Measurement: Using calipers/micrometers to verify dimensions, ensuring compliance with design specifications.
• Visual Inspection: Observing under standard lighting to detect cracks, defects, and foreign materials.
• 2D Image Measuring System: High-resolution, non-contact equipment for precise measurement of irregular shapes. 

6. Reliability Testing:

• Impact and Vibration Tests: Simulate shocks and vibrations during transport and use to ensure operational reliability.
• High Temperature Demagnetization Test: Verifies magnetic stability under high temperature for long-term performance.
• Damp Heat Test: Assesses resistance to humidity and corrosion in high-moisture environments. 

7. Packaging and Transportation:

• Screening: Eliminate defective items based on appearance and dimensions.
• Magnetizing and Alignment: Uniform magnetization and neat packaging as per customer requirements.  

8. Application Fields:

• Strong axial field: High energy product and field strength in a linear path.
• Magnetic Charging Interfaces (Type-C magnetic connectors)
• Built-in Micro Industrial Machine
• Compact form: Easy to integrate into cylindrical holes or grooves.
• Magnetic Connection Components for Smart Bands/Ear Hook Devices  

9. Usage Precautions:

• Handling: NdFeB is hard but brittle; avoid dropping, collisions, or scratches.
• Safe Operation: Due to strong magnetism, avoid bending—slide to separate to prevent pinching.
• Correct Installation: Follow polarity markings for proper installation to ensure device function.
• Storage Requirements: Store away from heat, moisture, and corrosive environments.
• Isolation: Keep away from hard drives, IC cards, and pacemakers due to strong magnetic interference.
