Abstract
Description
微細構造を有するマスター構成要素を生成する段階、
(任意的に)微細構造を有するマスター構成要素の面を金属化する又は微細構造を有するマスター構成要素の面に金属化層を塗布する段階であって、金が、好ましくは金属化に使用され、特に好ましくは、好ましくはクロミウムで作られた接着層が、金属化の前に塗布される、上記塗布する段階、
(好ましくはニッケル、又はニッケルを含有する)金属をマスター構成要素の好ましくは金属化された面上に電気メッキする段階(この場合に、少なくとも500μmの層厚の金属が好ましくは堆積される)、
(好ましくは)例えば電気メッキした金属層内の型彫りを通して、外側輪郭を生成することにより、金属が電気メッキされた加工物上に境界縁部処理を行う段階、そして任意的に、続けて型彫りによって生成した間隙内の加工物を鋸引きする段階、
任意的に、金属化中に、特にマスター構成要素を湿式化学溶解することによって生成したマスター構成要素の層を含む堆積した金属層(金属板又は金属箔として、その後の成形ツールの一部である)を分離する段階、
(任意的に)適切な場合に、先行する金属化において堆積された接着層(例えば、クロミウム)を、特にエッチングにより(例えば、特に、Cer(IV)−硝酸アンモニウムを用いて選択的に)除去する段階、
(任意的に)金属板又は金属箔を境界縁部処理する段階であって、第1に、構造保護部を堆積金属層内の補完微細構造に適用し、次に、境界縁部(すなわち、ここで生成した成形ツールの一部又は成形ツールのためにここで生成したツールインサートの外側成形)が処理され、構造保護が再度除去される上記境界縁部処理する段階。
この方法を用いて、補完微細構造を有する金属板又は金属箔が生成され、そしてそれが例えばホットスタンピング工程のためのポンチに適用され、又は射出成形工程における中空金型の内壁の一部であるという点で、成形ツールの一部又はツールインサートとして今や使用することができる。
