China Small Flexible Magnet Manufacturer — Precision Die-Cut Magnetic Components by UPSUN
Our Small Flexible Magnet Products
As a dedicated China Small Flexible Magnet Manufacturer, UPSUN specializes in producing precision die-cut small flexible magnets — compact ferrite rubber and bonded NdFeB magnetic components sized from as small as 5 mm × 5 mm up to 100 mm × 100 mm, in thicknesses ranging from 0.3 mm to 3.0 mm. Each small flexible magnet we manufacture is cut from high-quality calendered magnetic sheet using rotary die-cutting, flatbed die-cutting, or CNC kiss-cutting equipment, achieving dimensional tolerances as tight as ±0.2 mm and delivering clean, burr-free edges ready for direct integration into your product assembly line. Available in isotropic ferrite, anisotropic ferrite, and high-energy bonded NdFeB grades, our small flexible magnets provide reliable magnetic holding force in ultra-thin, lightweight form factors that rigid sintered magnets simply cannot match at this scale.
Small flexible magnets are the invisible workhorses behind countless everyday products — from the magnetic closure in a handbag clasp or gift box lid to the positioning magnet inside a smartphone case, the sensor trigger in a door alarm, and the adhesive-backed magnetic disc on a name badge. What makes UPSUN the preferred China small flexible magnet manufacturer is our ability to combine material science expertise with precision converting capabilities: we produce the base magnetic sheet in-house, then die-cut, kiss-cut, laminate, adhesive-back, print, or individually package each small flexible magnet to your exact specification. Whether you need 10,000 self-adhesive mini magnetic discs for a packaging closure application, 100,000 small flexible magnetic squares for a craft kit assembly line, or 1,000,000 precision-cut small flexible magnet strips for a consumer electronics OEM, UPSUN delivers consistent quality, tight tolerances, and competitive China factory pricing on every order.
About UPSUN — Your Precision Small Flexible Magnet Supplier in China
Ningbo Upsun Magnetic Technology Co., Ltd. is headquartered in Ningbo, one of China's most important deep-water port cities and a well-established manufacturing base for magnetic materials and precision converting. With over a decade of experience in flexible magnetic sheet production, UPSUN has invested in dedicated small flexible magnet converting lines that integrate high-speed rotary die-cutting, flatbed die-cutting, CNC kiss-cutting, automatic self-adhesive lamination, sheet-to-piece counting, and individual packaging — all designed to handle the tight tolerances and high piece counts that small flexible magnet orders demand. Because we manufacture the base ferrite and NdFeB flexible magnetic sheet in-house, we control quality from raw powder compounding through to finished die-cut pieces, eliminating the consistency risks that come with sourcing pre-made sheet from third parties.
UPSUN operates under a certified ISO 9001 quality management system with full compliance with RoHS, REACH, and EN 71 consumer safety standards. For small flexible magnet production specifically, our QC process includes incoming sheet Gauss testing across the full roll width, die-cut dimensional sampling with optical comparators, adhesive peel-strength verification, and AQL-based final inspection on every carton. We understand that when a customer orders 500,000 small die-cut flexible magnets, every single piece needs to match the approved specification — because even one out-of-tolerance magnet can cause a jam on an automated assembly line. That commitment to piece-level consistency is why packaging converters, consumer electronics OEMs, craft kit manufacturers, and promotional product companies worldwide trust UPSUN as their go-to China small flexible magnet manufacturer.
Why Choose UPSUN as Your China Small Flexible Magnet Manufacturer?
In-House Magnetic Sheet Production
We manufacture our own flexible ferrite and bonded NdFeB magnetic sheet through precision calendering, giving us direct control over magnetic material performance — including Gauss level, thickness uniformity, surface smoothness, and flexibility — before a single small flexible magnet is die-cut from the parent sheet. This vertical integration ensures batch-to-batch consistency that third-party converters cannot guarantee.
Precision Die-Cutting & Kiss-Cutting
UPSUN operates high-speed rotary die-cutters, hydraulic flatbed die-cutters, and CNC digital cutting tables configured specifically for small flexible magnet production — delivering clean, burr-free cuts in shapes as small as 5 mm diameter discs with dimensional accuracy of ±0.2 mm, at speeds exceeding 200 strokes per minute for high-volume orders.
Versatile Size, Shape & Material Options
We supply small flexible magnets in discs, squares, rectangles, ovals, rings, strips, and fully custom contour shapes — in ferrite isotropic (0.4–1.5 mm), ferrite anisotropic (0.5–3.0 mm), or bonded NdFeB (0.5–2.0 mm) grades — with optional self-adhesive backing (acrylic or 3M equivalent), PVC lamination, printed surface, or plain finish to match your application requirements.
Certified Quality & Safety Standards
Every small flexible magnet order is produced under our ISO 9001 quality system with full RoHS, REACH, and EN 71 compliance — essential when your magnets are destined for consumer packaging, children's craft products, or electronic devices sold in regulated markets. We provide batch-specific Gauss test data, dimensional inspection reports, and adhesive peel test results with each shipment.
Low MOQ with High-Volume Scalability
UPSUN accepts small flexible magnet orders starting from as few as 1,000 pieces for prototyping and sample evaluation, then scales seamlessly to production volumes of 100,000 to 5,000,000+ pieces per order using the same tooling and quality systems. Whether you are validating a new packaging design or ramping to full mass production, we support every stage of your product lifecycle.
Fast Logistics from Ningbo Port
Located within 30 minutes of Ningbo-Zhoushan Port — the world's busiest cargo hub — UPSUN ships small flexible magnet orders globally via FedEx, DHL, UPS, or ocean freight. Typical lead times run 7–18 working days from order confirmation to dispatch, depending on quantity, die-cut complexity, adhesive lamination requirements, and destination.
China Manufacturing Advantages for Small Flexible Magnets
China is the world's dominant producer of ferrite magnetic powder and NdFeB rare earth powder — the two raw materials that form the core of every small flexible magnet. By manufacturing both the parent magnetic sheet and the finished die-cut pieces in our Ningbo factory, UPSUN captures the full cost advantage of China's upstream supply chain: domestically sourced ferrite and NdFeB powder at 30%–40% lower cost than international market pricing, combined with highly efficient converting lines and a skilled workforce experienced in precision small-piece production. The result is finished custom small flexible magnetic components delivered at 40%–60% lower per-piece cost compared to equivalent products from converters in Europe, North America, or Japan — without any trade-off in dimensional accuracy, Gauss consistency, adhesive quality, or material safety compliance.
Piece-level quality at high volume is where UPSUN distinguishes itself from other China small flexible magnet manufacturers. Our converting lines feature inline laser dimensional gauging that verifies cut width and length on every stroke, Gaussmeter spot-check stations at fixed intervals, and automated piece-counting and stacking systems that ensure accurate quantity per bag and per carton. Any die-cut piece that falls outside the customer-approved tolerance window is ejected before it reaches the packaging station, maintaining an outgoing defect rate consistently below 0.3%. This precision converting discipline — combined with end-to-end traceability from magnetic sheet roll number to final China Small Flexible Magnet carton label — is why automated assembly operations, consumer goods brands, and industrial OEMs trust UPSUN as their long-term small flexible magnet manufacturing partner.
