Guide
Choose the retention strategy early
Adhesive bonding, insert molding, overmolding, staking, ultrasonic welding, and mechanical capture each carry different risks. The right choice depends on pull-out force, temperature, shock, vibration, field orientation, cosmetic requirements, and tooling economics.
Plan magnetization and inspection together
Some assemblies are easier to mold before magnetization, while others require a pre-magnetized part and careful fixture control. The inspection plan should verify magnet presence, polarity, orientation, position, flux output, and finished assembly dimensions.
Avoid late-stage launch surprises
Programs often run into trouble when the drawing specifies the magnet but not the retention method, assembly environment, validation tests, or allowable magnetic output window. A clear quote package reduces rework and helps align tooling, samples, and production controls.
