An injection moulding process for making a completely recyclable, multilayered article which contains:i) a rigid layer formed of a thermoplastic polymer andii) a foamed skin layer formed of a thermoplastic polymer compatible with the material of the rigid layer, byinjection moulding of the rigid layer into a mould composed of two sides,lifting one side of the mould, or change one side of the mould to obtain a small gap of between 3 to 4 mm between the rigid layer and the side of the mould lifted or changed andinjecting the foamed skin layer into the gap formed in step b).
