摘要： The invention relates to a method and device for the production of a multilayer plastic element, in which a plastic injection-moulded part is coated with at least one coating of 2-component thermosetting plastic. In accordance with the invention, the plastic element and the coating of 2-component thermosetting plastic are injection-moulded, successively and cycle-synchronously, in the same mould, whereby the reaction time of the 2-component thermosetting plastic is adapted to the time needed for injection-moulding the plastic element. A device for producing a multilayer plastic element by using an injection moulding machine is characterized in that, in the injection moulding machine (11), there is a RIM device (13) for introducing a 2-component thermosetting plastic into a multi-component injection moulding die. This makes it possible for the production of multilayer plastic elements to take place simultaneously, by using a plurality of moulds. For, while the coating of an earlier produced plastic element takes place in one mould, in a second mould the next plastic element is already being injection-moulded.
