Run of the mill neodymium magnets can not handle the heat of an overmolding process. They would have to be remagnetized after the molding process which is not an inexpensive or reliable process at best. SmCo can withstand the process, but size would need to be increased for equivalent strength and cost increases considerably.DavidF wrote:sometimes its just about repetition.... once you set up a toggle clamp clap press, it may take a couple of times to hit dimension. But once you do it will be repeatable... Thats what I'm trying to say, simple, repeatable... I also feel overmolding would be simple and accurate, Maybe thats just me but so be it...
If you want to encapsulate a neodymium magnet, ultrasonic or friction weld a cap in place. Machinable epoxies may prove durable enough for the application as well depending on the configuration.
