Manufacturing Process

This precision customized professional grade High-Power corrosion resistance  compact round disc nickel plating NdFeB magnet is manufactured through the following key processes:

● A high-speed grinding wheel shapes the magnet's surfaces with tight dimensional tolerances.

● Coolant fluid is applied to control heat, reduce surface stress, and ensure a smooth finish.

● The result is a uniform, precisely dimensioned magnet with clean edges—ideal for high-performance applications.

This precision step is essential for ensuring that the final magnets meet strict quality standards for use in motors, sensors, electronics, and aerospace components      

Surface Treatment & Plating

To enhance corrosion resistance and appearance:

Default Plating: Triple-layer Ni-Cu-Ni (customizable).

Standard Thickness: Ni (3μm) + Cu (5μm) + Ni (4μm).

Optional Plating: Single-layer Zn (5μm) for cost-sensitive projects.

Features:

✔ Salt spray & oxidation resistance

✔ Increased surface hardness (scratch-resistant)

✔ Improved gloss (ideal for exposed components)

Appearance & Dimensional Inspection

Visual Inspection: Under standardized lighting, trained QC staff check for cracks, chipping, inclusions, pores, or oxidation

Image Measurement System: High-res cameras and algorithms conduct non-contact 2D measurements, especially for complex or irregular shapes, ensuring efficiency and objectivity in mass production. 

Automated Intelligent Inspection: High-speed cameras with AI algorithms detect and reject defects (e.g., cracks, scratches, discoloration) and dimensional anomalies, improving yield and reducing human error.
