Drawing
Provide geometry, functional datums, magnetization direction, working gap and required contact surfaces.
Factory Tour · Process principles
Six material families. Different production routes.
Start with the material family and magnetic circuit. A rigid permanent magnet, a flexible sheet and a soft magnetic core require different forming routes, interfaces and acceptance conditions.
The producing site, applicable route and inspection scope are confirmed for the project.
Material routes
- Rigid permanent magnets
- Flexible compounds
- Soft magnetic cores
Different routes require different acceptance conditions.
Define the requirement
Bring the drawing, material and acceptance inputs.
Service conditions
State continuous and peak temperature, opposing field, exposure and handling constraints.
Process principles
Match the material family to its route.
Material selection changes forming, finishing, handling and verification requirements.
NdFeB · oriented powder to sintered magnet
Low-oxygen powder control, magnetic-field pressing and vacuum sintering precede brittle-material machining. Define the coating and bonding interface; agree dimensional inspection after coating.
SmCo · composition and thermal route
The 1:5 and 2:17 families use composition-controlled powder metallurgy and vacuum processing. Specify support contact, edge breaks, tolerances and handling constraints for the brittle component.
Ferrite · ceramic forming and sintering
Ceramic powder forming, controlled sintering and selected grinding establish the component. Confirm isotropic or anisotropic material, pole direction, ground faces and edge acceptance.
AlNiCo · cast or sintered
Casting forms molten alloy; the sintered route uses powder metallurgy. Select the route with geometry, working point, open-circuit handling, opposing fields and final magnetization.
Flexible · sheet forming and conversion
Compound forming and calendering lead to conversion and multipole magnetization. Define pole pitch, cut outline, backing and roll or flat-part delivery before profile inspection and packing.
Soft magnetic · core and winding
Powder cores and wound strip cores follow different material routes. Amorphous and nanocrystalline components use winding, finishing and controlled annealing. Review frequency, flux density, temperature and DC bias.
Verification and records
Keep the magnetic result tied to its test conditions.
Define the evidence
Agree critical characteristics, sampling and acceptance criteria. Keep grade references, dimensional requirements and the magnetic test conditions together.
Match the test to the component
For soft magnetic cores, specify loss and permeability measurement conditions; agree wound-sample or component testing where required.
Project review
Connect the route to your requirement.
Send the material or drawing definition, intended use and the acceptance records needed for review.
