Apparatus and method for the production of a component made of plastic material, and component made of plastic material

Embodiments described here concern a method and an apparatus for the production of a component made of plastic material suitable to be used as the containing body, or casing, of a household appliance, or as a receptacle. The component comprises a first layer and a second layer, which at least partly covers the first layer. Method for the production of a component (10) made of plastic material, suitable to form a containing body, or casing, of a household appliance (50), or of a receptacle, and provided with at least one transparent area (T), characterized in that said method comprises: - a first step of injecting a first opaque plastic material into a first molding volume (VI) defined between a punch (29) and a first matrix (30) provided with a first molding surface (33) for the production of a first internal layer (11), wherein during said first step the method provides to limit at least one portion of the first molding volume (VI) in order to produce an exposed area (S) in said first layer (11); - a second step of injecting a second at least partly transparent plastic material into a second molding volume (V2) defined between said first layer (11) obtained in the first injection step, said punch (29), and a second matrix (34) for the production of a second layer (12), wherein during said second injection step said method provides to cover said exposed area (S) with said second material so as to obtain a transparent area (T) in said component (10).
