摘要

Production of a surface comprises pouring polyurethane or a similar porous plastic that is resistant to heat distortion in the galvanic bath as starting material into the required mold; closing the pores in its surface with paraffin; applying a conducting lacquer on the closed surface; and depositing a metal or precious metal layer in an electrolytic electroplating bath.
