<p>The invention features the manufacture of assembly parts comprising two plastic workpieces, mutually movable with at least one configuration where their contact surfaces conform to complementary shapes. It comprises the following steps: a) forming a first piece (3') by bringing closer an external tooling (50, 51), the impression of which defines a generally convex surface and an internal tooling (40, 41) comprising at least one core (40) fitting into the internal surface volume; b) moving the first external tooling (50, 51) away and maintaining the internal tooling (40, 41); c) positioning a second external tooling (55), the impression of which defines with, the generally convex surface of the first piece, a volume of low thickness relative to the said convex surface; d) moulding the second piece (5') with a plastic material heated to a temperature higher than the melting point of the plastic material of the first piece (3'); e) spacing the toolings and extracting the assembly of two pieces (3', 5').</p> |
