China Neodymium And Ferrite Magnets Manufacturer & Supplier 
In high-end perfume packaging design, beyond the bottle's form and the fragrance itself, the tactile feel and closure experience of the cap equally reflect the brand's sophistication. Among numerous closure mechanisms, the magnetic cap has become a staple design for premium perfumes, with magnets serving as its core component. This article will provide a detailed overview of the primary materials, functions, and common specifications of these magnets.
Regarding the material, the primary material currently used is neodymium iron boron, including sintered neodymium iron boron and bonded neodymium iron boron. This material is renowned for its high magnetic energy product and stable performance, making it the preferred choice for magnetic bottle cap designs. It ensures perfume bottle caps remain secure during use while imparting a premium feel.
Regarding its magnetic poles, perfume bottle cap magnets are typically magnetized with a quadrupole structure. Compared to traditional unipole axial magnetization, quadrupole magnetization enables the magnet to deliver greater holding force, ensuring the cap remains securely attached during daily use. This not only enhances magnetic performance but also improves the tactile experience of opening and closing, making the cap's removal and replacement smoother and more natural.
For perfume bottle caps or other magnetic closures, sintered neodymium iron boron magnets are typically zinc-plated to reduce costs and feature a hollow ring shape.
Magnetic caps for perfume bottles are typically thin walled ring shaped, a design that facilitates installation while ensuring a tight fit with the bottle cap's internal structure. Common dimensions include: d32.8 × d27.8 × 2.5 mm, d27 × d23 × 2 mm, d23.8 × d19.8 × 2.5 mm, d22.5 × d18.5 × 2.5 mm, d26.3 × d21 × 2 mm, and d27 × d22 × 2 mm. Magnets of various sizes can be adapted to different perfume bottle cap specifications, meeting the design requirements for diverse bottle shapes.
