Method for manufacturing card product

摘要

A manufacturing method and a manufacturing apparatus for a card product such as a non-contact IC card product in which a circuit sheet is coated with a synthetic resin layer, in good efficiency and with a possibility to reduce the manufacturing cost of the product. The manufacturing apparatus has fixed molds 20 and a movable mold 30 which can freely approach or alienate from the other. The movable mold 30 has a piston 33 for reciprocal sliding movement in the movable mold 30 in the direction of approach and alienation. The fixed mold 20 has an injection port 22 for injecting the molten resin, and a concave part 23 is formed on the outer peripheral part surrounding the fixed mold end part opposite to the piston 33. To this concave part 23 there can be fitted a spacer 24 having the same face as the fixed type end face 20a or a spacer for replacement 242 which is replaceable with the spacer 24, and has a projected end face 242a of a certain height from the fixed mold end face 20.
