Finished magnets, made to drawing
Sintered and bonded permanent magnet components in ferrite and NdFeB systems — including rubber magnets, plastic magnets, multipole rings and custom assemblies.
Sintered Ferrite Magnets
烧结铁氧体磁器件
Pressed and sintered ferrite magnets, including motor tiles, radial rings and cylindrical magnets.
Bonded Ferrite Magnets
粘结铁氧体磁器件（橡胶磁 / 塑料磁）
Rubber magnets and plastic magnets produced by calendering, extrusion or injection molding.
Sintered NdFeB Magnets
烧结钕铁硼磁器件
High-energy sintered NdFeB magnets with tailored coatings, grades and magnetization patterns.
Bonded NdFeB Magnets
粘结钕铁硼磁器件
Compression- and injection-bonded NdFeB magnets for complex shapes and multipole magnetization.
Sintered vs bonded — which route fits your part?
A qualitative comparison to help shortlist a manufacturing route. Quantitative grade data will be published once Ruiyi confirms the component specifications.
| Aspect | Sintered ferrite / NdFeB | Bonded ferrite (rubber / plastic) | Bonded NdFeB |
|---|---|---|---|
| Process | Powder pressing + sintering | Calendering / extrusion / injection | Compression / injection bonding |
| Typical shape | Tiles, rings, blocks, cylinders | Strips, sheets, flexible rolls | Complex net-shape parts |
| Magnetization | Radial / axial / multipole | Multipole surface patterns | Free pole orientation |
| Assembly | Machined & coated | Laminated, die-cut, adhesive-backed | Insert-molded, over-molded |
| Data status | Specifications pending | Specifications pending | Specifications pending |
From axial poles to free multipole patterns
Injection-molded and bonded magnets allow pole orientation to be designed into the part rather than cut afterwards. Ruiyi supports radial, axial and multipole magnetization, insert molding and over-molding for rotor assemblies.
- Multipole rings and BLDC / stepping motor rotors
- Encoder target rings with repeatable pole pitch
- Flexible strips, sheets and die-cut gaskets
- Custom assemblies with shafts, housings and coatings
