Abstract
A method for manufacture of a plastic credit card includes steps of providing a mold with two shells. When the mold is closed the shells have opposed faces defining a cavity for producing the card. The general outline of the card is defined by the peripheral edges of the mold faces. An image support is placed in each shell; the molds are brought together. Then the plastic is injected to fill the mold and form the card. Plastic is delivered through a mold face and the inflowing plastic forces the respective image supports against opposite mold faces. After cooling, the mold card, now decorated on two faces, is removed from the mold.
Claims19
A method for manufacture of a plastic card, comprising the steps of:
- providing a mold with two shells, said mold when closed having opposed faces defining a first cavity for producing a card by molding, peripheral edges of said mold faces defining the general outline of said card;
- placing at least one of a film and a label adjacent each one of said shells as an image support, said film and label each supporting a respective image,
- bringing said mold shells together a boss extended from one said shell face into said first cavity when said mold is closed, said boss having an end surface spaced from the other said shell face and having a passage of an injection nozzle therethrough,
- providing an opening in the image support in one said shell;
- positioning said image support opening in alignment with said injection nozzle for flow of plastic through said opening;
- positioning the other said image support against the end surface of said boss in front of an outlet of said injection nozzle;
- injecting plastic through said outlet to fill said mold and form a card, said at least one of a film and label being forced against a respective shell face by said incoming plastic;
- whereby injected plastic flows between said image supports, said image supports being forced apart in opposite directions and pressed by the injected plastic against the face of a respective shell;
- cooling said molded card with said at least one of a film and a label adhering to respective sides thereof;
- and
- removing said card from said mold.
