Abstract

In a method of making plastic articles with embossed pattern, a plastic material is injection-molded in a cavity of a clamping unit of an injection molding machine to form an injection-molded plastic article. A pattern is embossed from a foil strip onto a previously injection-molded plastic article to form a finished plastic product with embossed pattern, whereby the embossing step is decoupled from the injection molding step and carried out separately from a clamping step of the clamping unit.
