The invention concerns moulded silicone components designed to be bonded on a support. The self-adhesive assembly comprises a stack having, successively, a silicone component to be bonded (R), a silicone-based adhesive layer (Cs), an intermediate sheet (Fi), an ordinary adhesive layer (Ce) and a protective sheet (Fp). The assembly is obtained by inserting the sheets (Fi, Fp) with their adhesive layers (Cs, Ce) in a mould (M), then in injecting silicone resin into the mould and leaving it to be cured. The invention is applicable to all moulded silicone components mounted by bonding to form sealing joints, locking joints, shock absorbers, stop elements.
