Wireless Charger Magnet Parts Manufacturer

Wireless Charger Magnet Parts are magnetic alignment components designed to center devices over wireless charging coils, improving positioning consistency and reducing slip/misalignment. Typical sets include a segmented NdFeB magnet ring and alignment magnets, with optional back iron and ferrite shielding / flux guiding layers.

We support custom sizes, segment counts, coatings, and adhesive-backed assemblies for phone cases, chargers, holders, vehicle mounts, and accessory ecosystems.

Core parts: segmented ring + alignment bar Options: back iron / ferrite / adhesive Customization: OD/ID/thickness/segments Inspection: polarity, flux, adhesion

Common Wireless Charger Magnet Components

Segmented Magnet Ring Assembly

Multi-segment NdFeB ring arranged for alignment and consistent “snap” feel.

Alignment Magnet Bar / Blocks

Directional alignment piece to improve positioning repeatability and orientation control.

Back Iron / Steel Plate

Optional steel layer for stronger holding force and improved magnetic circuit efficiency.

Ferrite Sheet / Flux Guide

Optional shielding/flux guidance layer to reduce metal interference and improve performance.

Adapter Ring Sticker

Adhesive-backed ring for cases and accessories; supports custom adhesives and shapes.

Custom Frames & Carriers

Plastic/steel carriers, locating holes, and integrated assemblies for production-ready mounting.

Matched Polarity Sets

Controlled polarity and flux output for stable assembly behavior and reduced variation.

OEM Custom Kits

Ring + bar + adhesive + (optional) ferrite/back iron in a single ready-to-assemble kit.

Typical Applications

Phone Cases & Accessoriesadapter rings, magnetic alignment kits for cases and add-ons
Wireless Chargerscoil centering, positioning stability, reduced misalignment in use
Car Mounts & Holdersstronger hold with back iron; reliable orientation with alignment magnets

Selection Guide & Key Specifications

Item Key Specs Why It Matters Notes / Options
Ring OD / ID / Thickness Outer/inner diameter, total thickness, tolerances Defines fit and coil centering performance Custom sizes available; share drawing or target device size
Segment Count e.g., 16 / 24 / 32 segments (custom) Impacts assembly layout and alignment feel We can recommend based on size and holding requirements
Magnet Grade & Coating NdFeB grade + coating (Ni / Epoxy / Zn, etc.) Controls holding force, reliability, and corrosion resistance Coating selected by environment and appearance requirement
Alignment Magnet Bar length/width/thickness, polarity direction Improves repeatability and prevents rotation/misalignment Polarity control & matching sets supported
Adhesive / Backing Adhesive type, thickness, heat resistance Ensures long-term bonding and assembly stability 3M series and custom adhesives (per requirements)
Ferrite / Flux Guide (Optional) Thickness, size, backing film Helps reduce metal interference and improve flux path Recommended for certain builds; we can propose a stack-up

Note: The best configuration depends on device stack-up (case thickness, coil location), target holding force, and whether ferrite shielding is required. Share your assembly structure for a faster recommendation.

Manufacturing & Quality Control

Assembly & Polarity Control Ring segmentation arrangement, polarity verification, matched sets, and fixture-based consistency.
Adhesive & Stack-up Options Adhesive-backed assemblies, custom carriers, and optional back iron/ferrite layers.
Inspection Flux checks, polarity marking, dimensional checks, adhesive adhesion verification (on request).

FAQ

What is included in a wireless charger magnet parts kit?
Common kits include a segmented magnet ring and alignment magnets. Optional layers include back iron (steel) and ferrite/flux guide sheets, plus adhesive backing and carriers.
What information do you need to recommend the right design?
Ring OD/ID/thickness, segment count, target holding force, application scenario (case/charger/mount), adhesive needs, and whether ferrite shielding is required.
Can you provide custom sizes and segment layouts?
Yes. We support custom diameters, thickness, segment count/layout, coatings, and assembly fixtures for stable production.
Do I need ferrite shielding / flux guide materials?
It depends on your device stack-up and nearby metal structures. Ferrite/flux guide layers can help improve flux path and reduce interference in some builds. Share your assembly structure for evaluation.
