Claims (4)
- 複数のインジェクタ(3a−3d)を介してプラスチック材料を射出成形する方法であって、
各々のインジェクタは、標準射出サイクルを含む設定サイクルに従って、個々の電子的にコントロールされるアクチュエータ(8a−8d)により閉じ位置と開き位置の間で制御されて配置され得るピンバルブ(7)を有し、
前記インジェクタの一部(3b、3c、3d)は前記インジェクタの他のもの(3a)よりも少ないプラスチック材料の量を射出する、方法において、
少なくともインジェクタの数及びプリントされる部品の寸法に従う、射出されるプラスチック材料の色を変更するプリセットの関数の、起動を促進し、
限定数の射出サイクルにてプラスチック材料の最大限の量を射出するように前記一部のインジェクタ(3b、3c、3d)を完全に開き、一方でその間他のインジェクタ(3a)を閉じられたままとし、これらにより色を変更するのに要求される成形操作の数を最小限にする、最適化シーケンスに従って作動する、ことを特徴とする
方法。 - 色を変更するのに要求される成形操作の数を最小限にする、最適化シーケンスは、有限要素解析により決定される
請求項1に記載の方法。 - アクチュエータ(8a−8d)は電気アクチュエータである
請求項1に記載の方法。 - 請求項1〜3のいずれか一に記載の方法を実装するための、プラスチック材料を射出成形するシステムであって、
前記設定サイクルに従って制御されてインジェクタ(3a−3d)のアクチュエータ(8a−8d)を起動するようにプログラムされた電子コントロールユニットを含み、
前記電子コントロールユニットは、射出されるプラスチック材料の色を変更するべく、前記プリセットの関数の起動を促進するように設計されている、ことを特徴とする
システム。
