Abstract
The invention relates to a matrix suitable for use in the replication of a plastic element having a positive microstructure, comprising a first wear-resistant layer that is supported by a carrier element, wherein the matrix comprises a heating means for supplying electrical heat energy through the wear-resistant layer or carrier element. The invention further relates to a plastic element producing machine and a method for the manufacture of a plastic element having a surface with a positive microstructure.
Claims16
A matrix for use in the replication of a plastic element having a positive microstructure, comprising a first wear-resistant layer, wherein said layer is supported by a carrier element having a thermal conductivity of less than 2 W/m/°K, wherein said layer consists of an electrically conducting or semi-conducting material having a resistivity of between 0.025 and 0.12 ohms×mm2/m, wherein said matrix is in the form of a singular structure mould cavity insert and is connected to a source of electrical heat energy via the first wear-resistant layer or a layer supporting the first wear-resistant layer by a connecting means.
