Custom Magnet Tooling and NRE

DFM, mold design, sample tooling, and NRE planning for custom injection molded magnet programs.

Best Fit For:Best for OEM teams that need a custom magnet part rather than an off-the-shelf catalog magnet.

Capability Highlights

Tooling review before prototype and production release
Molded geometry, insert, gate, and magnetization plan considered together
NRE planning for automotive and industrial OEM projects

Typical Engagement Scope

New sensor rotors
Custom motor rotors
Valve actuator magnets
Legacy conversion

Execution Focus

DFM review of wall thickness, draft, insert retention, and sensing datum
Tooling timeline and sample-build acceptance plan
Revision control between magnet drawing, mold design, and magnetization fixture

Program Evaluation Matrix

Program Metric	Typical Range	Procurement Value
Tooling release package	Drawing, material, magnetization, inspection, and sample plan	Injection molded magnets are tooling-led projects; unclear inputs create costly revision loops.

RFQ Preparation Checklist

2D/3D drawing, material target, magnetic pattern, and sensing datum
Operating temperature, vibration, media exposure, and lifetime requirement
Sample quantity, tooling target, annual forecast, destination, and PPAP needs

Risk and Mitigation

Brittle sintered magnet carried into a vibration-critical assembly: Review bonded magnet material and molded geometry when chipping, cracking, or adhesive failure can affect functional safety.
Magnetic pattern accepted without measurable criteria: Define flux density, pole count, angle error, sensing radius, concentricity, and inspection method before sample tooling.

Buyer FAQ

Why is tooling NRE required for injection molded magnets?

The mold and magnetization approach are custom to geometry, insert design, material flow, and magnetic pattern, so production-quality samples require dedicated tooling work.
