<p>A small article such as portable electronic token of the smart card type is manufactured by means of a reaction injection moulding technique in which electronic circuitry (1, 2) is encapsulated within a hardenable plastics material (8). The labels on the faces of the card (6) are used as a mould release agent to enable easy release of the token, once hardened, from the mould (10). The articles are conveniently manufactured by a continuous process using moving belts.</p> |
