Scope

Main Technical Content: 4.1 Materials 4.1.1 The selected plastic materials must comply with food-grade ABS or HIPS standards. 4.1.2 The magnetic cores should be made of magnetic steel materials with a thickness of ≥0.8mm. 4.1.3 The spheres should be made of magnetic steel materials with a thickness of ≥0.30mm. 4.1.3 The magnetic cores should be made of neodymium iron boron materials. 4.2 Installation of the Magnetic Cores As the core functional component of the product, to prevent detachment, the maximum diameter of the selected magnetic cores should be more than 10% larger than the opening diameter of the plastic components. During assembly, the magnetic cores should be installed using built-in or semi-built-in physical stoppers, not adhesives. 4.3 Dimensions 4.3.1 The diameter of the magnetic cores should be ≥5mm. 4.3.2 The diameter of the spheres (iron balls) should be ≥32mm. 4.3.3 The diameter of the magnetic rods should be ≥16mm, and the length should be ≥45mm. 4.4 Appearance 4.4.1 The magnetic cores should undergo surface treatment before installation, ensuring a smooth surface without burrs, rough edges, or delamination of coatings or rust defects. 4.4.2 After assembly, the magnetic rods and spheres should have a uniform surface color, no cracks, and no burrs or rough edges. 4.5 Surface Magnetic Flux Density The magnetic flux density (BB) of the magnetic cores should be ≥3000 Gs. 4.6 Magnetic Rod Pulling Force The pulling force (FF) of the magnetic rods should be ≥100g. 4.7 Drop Resistance A single magnetic rod or sphere should withstand 10 free falls from a height of 1.5 meters onto a concrete surface without surface cracks, damage, or detachment of the magnetic cores. 4.8 Tensile Strength of Embedded Magnetic Cores The tensile strength (WW) of the embedded magnetic cores should be ≥5kg.
