ABSTRACT:
Electrical components permanently applied to terminal carrier plates are cast with casting resin in a casting mould. The mould includes (a) a lower mould component, provided with a silicon rubber layer containing recesses for receiving the carrier plates, (b) a central mould component which is to be clamped down onto the lower mould component and is provided with chambers which are open at the top and at the bottom and which accommodate the electrical components to be cast, and (c) an upper mould component which is provided with flow openings for the common casting resin sprue. The invention can be used, for example, in the production of small annular core coils which are later to be used in film circuits.
