Custom Neodymium Magnets
A custom NdFeB magnet needs a clear physical definition and a measurable magnetic requirement. Axis Magnetics can review geometry, coating, magnetization, tolerance, and assembly fit so that quotation and sample discussions start from the same specification.
Each review starts with the application, then works through material, coating, magnetization, validation, origin, and production requirements.
Blocks, discs, rings, arcs, segments, and custom machined geometries should be defined around the available space and magnetic circuit. Include the dimensions that control fit and alignment. For a ring or arc, specify the relevant diameters, thickness, length or angle, and any orientation features clearly.
Separate critical-to-function dimensions from general tolerances. Show chamfers, radii, countersunk features, and acceptable edge conditions where needed. State how coating buildup is handled in the finished dimensions and review clearance, adhesive gaps, brittle edges, and handling alongside the geometry.
A grade callout and a finished-part measurement serve different purposes. Record the material requirement alongside the application output, operating temperature, and measurement method. The agreed acceptance criteria should describe what will be checked on the magnet or finished assembly.
Show axial, diametric, radial, or multi-pole requirements on the drawing, including pole locations and polarity where relevant. Agree on the magnetization and measurement setup before sampling. Include any polarity marking or orientation feature needed to keep assembly consistent.
Review corrosion exposure, adhesive bonding, overmolding, press-fit contact, cleanliness, and cosmetic requirements when selecting a coating. Candidate options already considered in NdFeB sourcing include NiCuNi, epoxy, zinc, parylene, e-coat, and encapsulation. The selected protection and validation should fit the actual use.
Specify whether acceptance is based on surface gauss, flux, pull force, torque, or an application-level sensor response. Record the test position, air gap or fixture conditions, units, and acceptable output window as relevant. This lets the sample discussion distinguish a geometry problem from a measurement or magnetic-circuit issue.

Direct answers for sourcing, engineering, and compliance teams reviewing this magnet path.
Include geometry, critical tolerances, material requirement, coating, magnetization direction or pole pattern, and the magnetic inspection requirement. Add orientation marks, edge conditions, finished dimensions, and assembly constraints when relevant.
Those geometries can be reviewed for sourcing. Feasibility depends on dimensions, edge condition, coating buildup, magnetic orientation, handling, and the proposed manufacturing route. Resolve those requirements before approving the sample specification.
The grade is one part of the specification. Geometry, coating, magnetization, temperature, magnetic-circuit conditions, and the measurement setup also affect whether the finished magnet meets the application requirement.
