One-Shot Magnet Molding

Advanced injection molding technique that consolidates the magnet, carrier, and mechanical features into a single molded component.

Best Fit For:Best for value engineering (VAVE) teams looking to redesign multi-part sintered magnet assemblies into cost-effective single parts.

Capability Highlights

Combines gears, mounting flanges, and magnetic poles into one part
Removes the need for multi-piece rotor assemblies
Reduces total cost of ownership (TCO) for high-volume automotive programs

Typical Engagement Scope

HVAC actuator gears
Seat motor assemblies
Complex position-sensor carriers

Execution Focus

Mold flow analysis to ensure complete filling of complex mechanical features
Magnetic powder alignment within thin-wall gear sections
Dimensional stability of the integrated mechanical features

Program Evaluation Matrix

Program Metric	Typical Range	Procurement Value
Part consolidation ratio	Typically reduces 2-4 components down to 1	Fewer parts mean fewer supply chain risks, zero assembly errors, and eliminated adhesive curing bottlenecks.

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
Current BOM, assembly drawing, and mechanical load requirements for the carrier features

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

Can the one-shot part have non-magnetic areas?

The entire part is molded from the magnetic compound, but only specific areas are magnetized. The non-magnetized sections act purely as structural or mechanical elements.
