By a method of producing articles, including articles with very fine outlines, a shaping of the article is carried out while said article is in the amorphous state, whereafter the shaped article is heated to the crystallization temperature so as to be subjected to a curing. In this manner it is utilized that the shaping is easily carried out as long as the material in the amorphous state at a temperature between the glass transition temperature and the crystallization temperature as the curing can take place afterwards. Subsequently, further shaping is substantially impossible. Such a method renders it possible by a simple procedure to provide articles with very fine outlines of a hard material, which has not been possible previously. The articles in question can for instance be moulds for a serial production of other articles with very fine outlines.
