Depending on the application, cores can be supplied uncut or cut; in the latter case, they are impregnated beforehand. After winding, an annealing heat treatment is recommended to align the magnetic domains, thereby maximizing the magnetic performance of the core.

ELESA toroidal and oval magnetic cores are produced by winding magnetic strip around circular or oval tooling, normally using a single strip width.
Available as uncut or cut cores, they can be supplied uncoated, with an insulating epoxy powder coating, or protected by polyamide covers, depending on the requirements of each application.
ELESA rectangular magnetic cores are produced by winding magnetic strip around rectangular tooling and can be made from one or several strip widths.
Available as uncut or cut cores, they are supplied without any special external finish.
UNICORE overlapped magnetic cores, also known as distributed-gap cores, offer higher efficiency and lower losses than traditional cut cores or C-cores.
Their manufacturing process does not require winding tooling, and they are supplied assembled, without any special external finish.
