Abstract
【解決手段】本装置は、プラスチック材料溶融物(K)を均質化するために、複数のフローチャンネル(S1−Sn)をもつ均質化エレメント(41)を有し、複数のフローチャンネルは、長さ(L1−Ln)、断面積及び断面形状の少なくとも1つに関して異なっている。均質化エレメントを通って流れるとき、プラスチック材料での溶融物は複数の部分ストリーム(T1−Tn)に分割され、複数の部分ストリームは、それぞれの場合において、組み合わされたフローチャンネルを通って流れる。それぞれのフローチャンネルを離脱するとき部分ストリームは異なるフロー速度(v1−vn)を有し、それでプラスチック材料溶融物は均一なフローに遷移して膨張し、剪断され、その結果、プラスチック材料溶融物を均質化することが可能となる。
