Abstract

A double molding process whereby at least one sign is produced on a product while the product is molded. The product has an inner core and an outer cover. In the process, the inner core is molded with a first molding material. The inner core has at least one side provided with a groove in the shape of the sign to be produced. The inner core also has at least one other side provided with at least one channel leading within the inner core to the groove. The outer cover is then molded onto the inner core with a second molding material in such a manner that the one side of the inner core is not covered by the second molding material and thus remains visible. The channel of the other side and the groove of the one side are both filled up with the second molding material to produce the sign on the side of the product. This double molding process allows production of a sign, such as a name, a number, a logo, a trademark, or any other type of symbols conveying information, on a product while the product is molded, the sign lasting all throughout the working life of the product by virtue of its construction.
