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.
