Custom Neodymium Magnets

Made-to-drawing customization for your unique applications.

Osenc helps OEM buyers, engineers, and procurement teams source custom neodymium magnets with the right shape, size, grade, coating, tolerance, and magnetization direction.

Drawing-Based Customization

We review your drawing, dimensions, tolerance, grade, coating, and magnetization direction before quoting.

Application-Focused Suggestions

We consider working temperature, pull force, corrosion risk, assembly method, and end-use conditions.

Sample Before Production

For new custom projects, sample approval helps confirm size, coating, magnetization, and performance.

Export-Ready Packaging

Magnets can be packed according to size, magnetic strength, quantity, and shipping method.

What Can Be Customized?

Shape

Disc, ring, block, bar, arc, segment, cone, cylinder, and irregular shapes.

Size

Diameter, length, width, thickness, holes, slots, chamfers, and custom dimensions.

Grade

N35 to N55 and temperature grades based on performance needs.

Coating

NiCuNi, zinc, epoxy, gold, parylene, PTFE, and other coating needs.

Magnetization

Axial, diametrical, radial, multi-pole, or application-specific direction.

Tolerance

Standard or tighter tolerance according to your assembly requirements.

Packaging

Bulk packing, separated packing, export packing, or magnetic shielding if needed.

Regular and Irregular Custom Magnet Shapes

Custom projects can use standard magnet forms with non-standard dimensions, or irregular shapes for limited assembly space and special magnetic field requirements.

Disc

Ring

Block

Arc

Segment

Countersunk

Irregular Shapes

Choose the Right Grade, Coating, and Magnetization Direction

Grades for Different Performance Needs

Higher grades can provide stronger magnetic performance in limited space, but the right choice also depends on size, air gap, working temperature, coating, and assembly design.

Coating Options for Different Environments

Coating is not decoration. It affects corrosion protection, final dimensions, fitting risk, and long-term use in the actual application.

Magnetization Direction

Axial, diametrical, radial, multi-pole, and custom magnetization options help the magnet match the final assembly and magnetic field design.

From Drawing Review to Production

1. Send Your Drawing

Upload your drawing, sample photo, or application requirements through the RFQ form.

2. Engineering Review

We review dimensions, tolerance, grade, coating, magnetization direction, and use conditions.

3. Quotation & Sample Plan

You receive a quotation and sample plan based on material, quantity, tooling, and lead time.

4. Sample Approval

Samples are produced and checked before moving to volume production.

5. Volume Production

After approval, production starts with dimensional, coating, magnetic, and packaging checks.

What Information Should You Send for a Fast Quote?

Better RFQ information means fewer repeated questions, faster quotation, and a lower risk of sample mistakes.
