3. Surface Treatment & Coating Technology

To enhance this customized industrial grade fast magnetic response strong magnetic stable roof shaped magnet’s corrosion resistance, surface quality, and magnetic stability, the following treatments are used:

Laser Sealing

High-precision laser treatment further seals surface micro-cracks, effectively enhancing the magnet's salt spray resistance, reaching over 1000 hours.

Nickel Plating (Ni-Cu-Ni Structure)

A three-layer composite coating process is used: copper plating on the inner layer, nickel plating in the middle, and an outer layer of nickel. This structure balances mechanical strength and corrosion resistance, significantly improving the product's protection in harsh environments such as humidity, salt spray, and acidic/alkaline conditions. The nickel layer is dense and hard, effectively preventing rust and chemical corrosion while offering excellent wear resistance. This extends the magnet's lifespan in high-frequency assembly and long-term operation environments. Additionally, the bright silver metallic sheen gives the product a clean, aesthetically pleasing appearance, meeting both functional and aesthetic requirements for industrial and consumer products.

4.Appearance & Dimensional Inspection

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

Image Measurement System: High-resolution cameras combined with intelligent algorithms enable contactless two-dimensional measurement, particularly suited for assessing intricate or non-standard shapes. This approach ensures high efficiency and consistent objectivity in large-scale manufacturing.

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.

5. Reliability Testing

Impact & Vibration Test: Simulates shipping and usage conditions to ensure operational stability.

6.Packaging & Transportation

Quality Control: Every magnet undergoes 100% inspection using calipers, projectors, and automated systems to ensure no defects like cracks, chips, oxidation, or coating issues.
