Method for preparing a decorated insert and continuous insert moulding operation.

摘要

A method is disclosed for the preparation of a thermoformable transfer film that may be pre-cut or is pre-positioned for continuous application during the forming of plastic articles by an insert moulding decorating technique. A carrier film (2) is first bonded to the transfer film (4) from which the transfer is prepared, to form a composite (14). The composite is then printed with appropriate decorating indicia on the free surface of the transfer film component thereof. Printing may be single-stage or multi-stage, depending upon the indicia desired, and a subsequent metalization of the transfer film may be performed. The fully printed composite is then indexed into position and thermoformed to form the insert (66) which later may be indexed directly into the mould chamber (80). The insert may be die-cut after its formation or prior to thermoforming. The present method facilitates the decoration of insert moulded products in a manner which eliminates the need for conventional insert moulding.
