Advanced injection molding technique that consolidates the magnet, carrier, and mechanical features into a single molded component.
One-Shot Magnet Molding is most relevant when best for value engineering (VAVE) teams looking to redesign multi-part sintered magnet assemblies into cost-effective single parts. Typical oem capability programs include HVAC actuator gears, Seat motor assemblies, and Complex position-sensor carriers, so the early review should confirm mold flow analysis to ensure complete filling of complex mechanical features.
Before sample tooling, align on 2D/3D drawing, material target, magnetic pattern, and sensing datum and operating temperature, vibration, media exposure, and lifetime requirement. The first acceptance check is part consolidation ratio (Typically reduces 2-4 components down to 1), because fewer parts mean fewer supply chain risks, zero assembly errors, and eliminated adhesive curing bottlenecks.
The main risk is brittle sintered magnet carried into a vibration-critical assembly; control it by review bonded magnet material and molded geometry when chipping, cracking, or adhesive failure can affect functional safety. Also review validation handoff and magnetic pattern accepted without measurable criteria before moving from prototypes to repeat production.
| 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. |
| Validation handoff | Operating temperature, vibration, media exposure, and lifetime requirement | It connects One-Shot Magnet Molding design intent to sample approval, lot inspection, and production sourcing decisions. |
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.
Include 2D/3D drawing, material target, magnetic pattern, and sensing datum, operating temperature, vibration, media exposure, and lifetime requirement, and sample quantity, tooling target, annual forecast, destination, and PPAP needs. If the part is tied to automotive or safety-critical sensing, also include PPAP, traceability, and magnetic test expectations.
