Abstract
The invention relates to a method for producing objects and object parts formed by an assembly comprising at least two plastic parts (10 and 5; 10′ and 5′), which can move in relation to one another with at least one degree of freedom and which are provided with surfaces having at least partially complementary shapes such that, in at least one geometric configuration, they are solidly interconnected on a common surface (11; 11′) in close, clearance-free contact The inventive method comprises the following steps: 1) molding of a first part (10, 10′) by compression or injection; 2) removal of the second tool, the first part (10, 10′) remaining solidly connected to the first tool which serves as a piece of support equipment or is installed on a piece of support equipment (60); 3) compression molding of the second part using the whole (110) of the first part which is integral to the support equipment and a third tool; 4) removal of the first support tool (60) and the third tool (55) and extraction of the assembly (200) thus formed.
