Abstract

PURPOSE: A thin metal layer is formed on the surface of plastic molds which are made using the master mold by deposition, whereby mass production is possible even in lenses with complicated shapes in low costs and the release of products is ready on molding, thus, giving products with good surface conditions.
CONSTITUTION: The end of stainless or glass rods are cut or grounded to form the same shape as the prescribed lens which is used as the master mold (5). Then the master mold is placed in vessel 6 at the top and a synthetic resin is poured therein. After cured, the resin is taken out of vessel 6 and the master mold 5 is removed, thus plastic 3 being given. Meanwhile silver oxalate is dissolved in water at a ratio of 20 g. of the salt in 1l of water and an adequate amount of ammonia to form a solution. Mold 3 is immersed in the solution and ammonia is added dropwise to deposite silver on the surface by silver-mirror reaction, whereby metal thin layer 4 is formed.
