Patent number: 10155329Abstract: There is described an apparatus for performing the in-mold decoration method with an injection tool (1). The injection tool (1) has a first tool portion (11) having a first mold recess (13) and a second tool portion (12) having a second mold recess (15) corresponding to the first mold recess. The second tool portion (12) has at least one injection passage (12e), wherein a portion of an endless decorative film (16) can be arranged between the first tool portion (11) and the second tool portion (12). The mold recess (13) of the first tool portion (11) has a raised edge region (14) extending in a closed configuration around the mold recess (13) and having an end face (14s) which is flattened or rounded or pointed in cross-section. The second tool portion (12) has a corresponding end face (12s) parallel to the end face (14s) of the raised edge region (14).Type: GrantFiled: October 4, 2016Date of Patent: December 18, 2018Assignee: LEONHARD KURZ STIFTUNG & CO.

Patent number: 9505154Abstract: The invention relates to a mould (1) for back-injection of a plastic film (4) with molten plastic, and a corresponding process for producing a plastic moulded article in the cavity (11) formed by a first and second mould part (2, 3). The first mould part (2) has a decorating surface zone (21), a clamping surface zone (22) arranged outside of the latter, and a recessed zone (23) arranged at least outside of the decorating surface zone (21). The second mould part (3) has an inlet (31) for the molten plastic and a projecting zone (33). The projecting zone (33) is arranged so that, when the tool is closed, it engages with the recessed zone (23), in order to hold the plastic film (4) arranged between the first mould part (2) and the second mould part (3), lying on the clamping surface zone (22) of the first mould part, in the recessed zone (23) under tension.Type: GrantFiled: February 8, 2012Date of Patent: November 29, 2016Assignee: LEONHARD KURZ STIFTUNG & CO.
