Magnetic Ring Assembly (Open C‑Shape)
Beschreibung
Outer Diameter(DIA)54mm
Inner Diameter(DIA)46mm
Thickness(T) 2.0mm
Our open C-shape split magnetic ring adopts a notched crescent structure for easier assembly and disassembly. It is widely used in magnetic positioning, low-power wireless charging and injection molding magnetic accessories. As a professional magnetic hardware manufacturer, we customize sizes, magnetic strength and surface plating for global clients, and provide sample testing, small trial orders as well as stable bulk supply all the time.
● Core Advantages of Open C Shape Magnetic Ring Assembly
‑ Open notch C-type structure, convenient for quick embedding and disassembly during production assembly.
‑ Split splicing design, flexible size adjustment, low processing cost and cost-effective for mass production.
Monolithic closed magnetic ring with uniform magnetism for wireless charging modules
‑ Standard NdFeB magnetic core with stable basic magnetism, suitable for low magnetic demand scenarios.
‑ Thin flat ring body, easy to be embedded into plastic shells without complicated mold transformation.
‑ Multiple anti-corrosion surface treatments including nickel plating, gold plating and epoxy coating for regular working environments.
● Comparison: Open C-Shape VS Closed O-Shape Magnetic Ring
‑ Magnetic circuit performance: C-shape with open notch has incomplete magnetic loop and obvious magnetic flux leakage; closed O-shape forms full loop with uniform magnetic field.
‑ Application range: C-shape fits simple positioning, low-cost consumer electronics; O-shape for high-precision sensing, stable wireless charging and high-end equipment.
‑ Injection molding performance: C-shape notch may scratch plastic during molding; seamless O-ring causes no damage to housing and molds.
‑ Service life: C-shape split structure is easy to shift under long vibration; integral closed O-ring has no loose risk.
● Main Application Scenarios
Dual-device fast charging stand with wood grain design for smartphone and smartwatch
‑ Low-cost consumer electronic accessories: portable small wireless chargers, simple magnetic positioning modules.
‑ General injection molding embedded magnetic parts: low-demand plastic smart home small parts, toy fittings.
‑ Light magnetic positioning components: portable charging brackets, simple magnetic adsorption decorations.
‑ Daily 3D ordinary toys: low-standard magnetic splicing toy models.
