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.<\/div>\n

\u25cf Core Advantages of Open C Shape Magnetic Ring Assembly<\/p>\n

\u2011 Open notch C-type structure, convenient for quick embedding and disassembly during production assembly.<\/p>\n

\u2011 Split splicing design, flexible size adjustment, low processing cost and cost-effective for mass production.<\/p>\n

\"Two

Monolithic closed magnetic ring with uniform magnetism for wireless charging modules<\/p><\/div>\n

\u2011 Standard NdFeB magnetic core with stable basic magnetism, suitable for low magnetic demand scenarios.<\/p>\n

\u2011 Thin flat ring body, easy to be embedded into plastic shells without complicated mold transformation.<\/p>\n

\u2011 Multiple anti-corrosion surface treatments including nickel plating, gold plating and epoxy coating for regular working environments.<\/p>\n<\/div>\n<\/div>\n

\n
\n

\u25cf Comparison: Open C-Shape VS Closed O-Shape Magnetic Ring<\/p>\n

\u2011 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.<\/p>\n

\u2011 Application range: C-shape fits simple positioning, low-cost consumer electronics; O-shape for high-precision sensing, stable wireless charging and high-end equipment.<\/p>\n

\u2011 Injection molding performance: C-shape notch may scratch plastic during molding; seamless O-ring causes no damage to housing and molds.<\/p>\n

\u2011 Service life: C-shape split structure is easy to shift under long vibration; integral closed O-ring has no loose risk.<\/p>\n<\/div>\n<\/div>\n
