A method for producing injection-moulded and coated moulded pieces having the following steps: a) associating of mould tool halves (5, 5', 5") of a first mould tool side to mould tool halves (5, 5', 5") of a second mould tool side of an injection moulding machine, so that at least a first mould tool of Type 1 and a first mould tool of Type 2 are formed, wherein a mould tool (4, 4') is formed respectively from a mould tool half (5, 5', 5") of the first mould tool side and from a mould tool half (5, 5', 5") of the second mould tool side; b) closing of the mould tool of Type 1 by moving the first mould tool side and/or the second mould tool side along a closing direction; c) injection moulding of a moulded piece in the first mould tool of Type 1; d) opening of the mould tool of Type 1 by moving the first mould tool side and/or the second mould tool side along the closing direction, wherein at least the moulded piece injection-moulded in step c) in one of the mould tool halves (5, 5', 5") remains on one of the two mould tool sides (2, 3); e) displacing and renewed associating of the mould tool halves (5, 5', 5"), so that a second mould tool of Type 1 and a second mould tool of Type 2 is formed and additionally the moulded piece injectionmoulded in step c) is arranged in the second mould tool of Type 2; f) cyclic repetition of steps b) to e), wherein alternately in step e) the first mould tool of Type 2 is formed from step a) or the second mould tool of Type 2 is formed from step e); wherein • the closing of the mould tool of Type 2, which has the moulded piece previously injection-moulded in step c), takes place during step c) by moving only one of the mould tool halves (5, 5', 5") of the mould tool of Type 2 along the closing direction; • the moulded piece injection-moulded in step c) in the first or in the second mould tool of Type 2 is coated during step c), characterized in that • the mould tool of Type 2, after the closing of the mould tool of Type 1, remains partially open, and • the opening of the mould tools of Type 2 takes place simultaneously by the movement of the first mould tool side and/or of the second mould tool side in the closing direction in step d), wherein the injection moulded piece coated in the second mould tool of Type 2 remains on the respectively other mould tool side in a mould tool half (5"), as the moulded piece injection-moulded in step c). a) associating of mould tool halves (5, 5', 5") of a first mould tool side to mould tool halves (5, 5', 5") of a second mould tool side of an injection moulding machine, so that at least a first mould tool of Type 1 and a first mould tool of Type 2 are formed, wherein a mould tool (4, 4') is formed respectively from a mould tool half (5, 5', 5") of the first mould tool side and from a mould tool half (5, 5', 5") of the second mould tool side; b) closing of the mould tool of Type 1 by moving the first mould tool side and/or the second mould tool side along a closing direction; c) injection moulding of a moulded piece in the first mould tool of Type 1; d) opening of the mould tool of Type 1 by moving the first mould tool side and/or the second mould tool side along the closing direction, wherein at least the moulded piece injection-moulded in step c) in one of the mould tool halves (5, 5', 5") remains on one of the two mould tool sides (2, 3); e) displacing and renewed associating of the mould tool halves (5, 5', 5"), so that a second mould tool of Type 1 and a second mould tool of Type 2 is formed and additionally the moulded piece injectionmoulded in step c) is arranged in the second mould tool of Type 2; f) cyclic repetition of steps b) to e), wherein alternately in step e) the first mould tool of Type 2 is formed from step a) or the second mould tool of Type 2 is formed from step e); wherein • the closing of the mould tool of Type 2, which has the moulded piece previously injection-moulded in step c), takes place during step c) by moving only one of the mould tool halves (5, 5', 5") of the mould tool of Type 2 along the closing direction; • the moulded piece injection-moulded in step c) in the first or in the second mould tool of Type 2 is coated during step c), characterized in that • the mould tool of Type 2, after the closing of the mould tool of Type 1, remains partially open, and • the opening of the mould tools of Type 2 takes place simultaneously by the movement of the first mould tool side and/or of the second mould tool side in the closing direction in step d), wherein the injection moulded piece coated in the second mould tool of Type 2 remains on the respectively other mould tool side in a mould tool half (5"), as the moulded piece injection-moulded in step c). • the closing of the mould tool of Type 2, which has the moulded piece previously injection-moulded in step c), takes place during step c) by moving only one of the mould tool halves (5, 5', 5") of the mould tool of Type 2 along the closing direction; • the moulded piece injection-moulded in step c) in the first or in the second mould tool of Type 2 is coated during step c), characterized in that • the mould tool of Type 2, after the closing of the mould tool of Type 1, remains partially open, and • the opening of the mould tools of Type 2 takes place simultaneously by the movement of the first mould tool side and/or of the second mould tool side in the closing direction in step d), wherein the injection moulded piece coated in the second mould tool of Type 2 remains on the respectively other mould tool side in a mould tool half (5"), as the moulded piece injection-moulded in step c).
