Company Profile

Jimmy Su - Materials Scientist

Injection Magnets combines Japanese tooling know-how with China-based manufacturing scale for precision injection molded magnets.

We help automotive, EV, HVAC, and micro motor buyers translate custom magnet rotor drawings into manufacturable injection molded magnet programs. Backed by the Advanced Manufacturing Division of Linkup Precision, our engineering team brings Japanese precision tooling standards to scalable China-based manufacturing.

Focused Category

Injection Magnets is built around injection molded magnets, bonded NdFeB/ferrite components, and custom magnetic rotors, not broad commodity magnet trading.

Engineering First

We help buyers clarify material, resin, pole pattern, insert design, tolerance, and magnetic acceptance criteria before tooling release.

Automotive Mindset

The site is structured for sensor, actuator, valve, and micro motor programs where CTQ definition and release evidence matter.

Capability Matrix for Buyers

Capability Area	What We Support	Buyer Value
Material Selection	Bonded NdFeB, bonded ferrite, PPS, PA, PEEK, and application-specific material tradeoffs.	Balances magnetic output, temperature resistance, cost, and molded geometry.
Molding Integration	Insert molding and overmolding around shafts, hubs, bushings, and carriers.	Reduces glue joints, part count, alignment drift, and assembly handling risk.
Magnetization	Radial, diametrical, axial, multi-pole, and sensor-specific magnetic patterns.	Turns the magnet into a repeatable sensor or motor function, not only a molded part.
Quality Evidence	CTQ review for dimensions, insert retention, visual condition, and magnetic output.	Supports sample approval, PPAP-oriented discussion, and repeat production readiness.

Automotive Standard Production & QC Flow

Our quality control process is strictly aligned with automotive PPAP (Production Part Approval Process) requirements.

Commercial Scope

Custom injection molded magnet and bonded magnet RFQs
Sample, tooling, pilot, and mass-production discussions
Automotive sensor, EV actuator, HVAC valve, and micro motor sourcing support

Trust and Documentation

Technical communication via [email protected]
Traceable drawing, material, and magnetization revisions
Quality and compliance file support by project scope

Custom Magnet Program Workflow

Requirement alignment: confirm application, geometry, material, insert, environment, and magnetic function.
DFM and tooling review: check wall thickness, draft, gate strategy, insert retention, and magnetization feasibility.
Sample governance: define CTQ dimensions, magnetic inspection, visual gates, and validation evidence before sample PO.
Production readiness: align lot traceability, inspection records, packaging, and delivery rhythm for approved programs.

Next Pages for Qualification Teams

Products for molded magnet family comparison and selection inputs.
Solutions / Applications for sensor, motor, valve, and harsh-environment use cases.
OEM Capabilities for tooling, insert molding, magnetization, and quality controls.
