Abstract
A method of producing a decorative pattern on a plastic card housing an etronic circuit in an injection molding machine, includes the steps of introducing and positioning a film, which has applied on at least one surface thereof a decorative pattern, in an open cavity of the injection molding machine, closing the cavity so that the film is fixed and clamped in position, after the closing of the cavity, inserting an electronic circuit chip through an aperture into the mold cavity, injecting a support composition for the card into the mold cavity, and after termination of the injection process, removing the gate or any excess material from the periphery of the card, opening the mold cavity and removing the decorated card.
Claims6
A method of producing a decorative pattern on and placing an electronic circuit in a plastic card in an injection molding machine, said method comprising the steps of:
- (a) introducing and positioning a first film, which has applied on at least one surface thereof a decorative pattern, over an open mold cavity in a mold of the injection molding machine;
- (b) closing the mold cavity so that the first film is fixed and clamped in position therein;
- (c) after tile closing of the mold cavity, inserting, an electronic circuit chip through an aperture in the mold into the mold cavity to position the chip in the cavity;
- (d) subsequently injecting a support composition for the card into the mold cavity to adhere to the first film and chip and to form the card;
- and
- (e) thereafter, removing excess material, opening the mold cavity and removing the card.
