Assembly for overmolding soft product on e.g. knife handle in agri-food industry, has partially chemical compatible products overlapped for realizing progressive molding, where products are reinforced by increase of relative surface

摘要

The assembly has partially chemical compatible products whose adherence is reinforced to avoid separation of the products by a complementary mechanical connection. The connection includes geometrical forms comprising a comb (6). The products are overlapped with each other to realize progressive molding, where the products are reinforced by the increase of relative surface representing overlap of the teeth. The comb is defined for each tooth by overlap distance, depth of teeth, thickness of last tooth and of soft tooth, bottom radius and tip radius of teeth and angle of the teeth.
