Matrix, method of producing and using the matrix and machine including the matrix

摘要

The invention relates to a method of producing a matrix suitable for use in a plastic element-producing machine, a matrix produced in accordance with the method and use of such a matrix to form a plastic element. One side of the matrix is provided with a negative microstructure which is replicated in plastic material to form a positive microstructure on a plastic element, wherewith the matrix can be produced by applying a layer of material to the positive microstructure side of a master. The positive microstructure side of the master has a thin wear-resistant layer which serves as a first wear surface, wherewith said layer will present irregularities which correspond essentially to the microstructure, and wherein at least said irregularities are filled-in with a plastic composite so as to form a carrier element for supporting the first wear layer. The layer can further be provided with means for supplying heat energy to said matrix.
