Injection-compression moulding processes for the production of complex shaped products made of elastomeric material

摘要

method of injecting - compression for the realisation of an article (15) vulcanizzabile in elastomeric is composed of: a step in which a nozzle injection by means of injection (8) is introduced into a semistampo less (1) a material fluid (7) elastomeric), the pressure of injection, a volume greater than that of the print.the excess material (10), the volume of the print being collected outside it in a recess (9) located opposite the injection nozzle (8), and connecting with the fingerprint.and a stage for forming, during which the injection nozzle (8) is replaced by a sealed fluid element of identical form (13) but devoid of withdrawal (9) to push for compressionthe excess material (10) within the footprint, until hardening.
