Production of molded articles for use as permanent magnets

摘要

Production of molded articles from a work piece comprises attachment of the work piece to a substrate by means of two separate adhesive layers. A process for the production of molded articles (2) by separation or detachment of the article (2) from or out of a work piece (1) or processing of a work piece (1) to one or more articles (2), whereby the work piece (1) is fixed to a substrate (3) by means of adhesives (4,5) during the separation. A first adhesive composition (I) is applied between (3) and (1) to form a first adhesive layer (4) and a second adhesive composition (II), that is different to (I) is applied between (3) and (1) to form a second adhesive layer (5). The adhesive layers (4,5) are hardened and the separated articles (2) are separated from the detached substrate piece (6) followed by cleaning of (2) to remove residual adhesive.
