NOVELTY - This utility model claims one kind of the surface's processing mould cavity surface's said mould with one layer graphene nano-thin film. The thickness of said graphene nano thin film's at 0.05 (mu) m to 2 (mu) m. The surface treatment's core's mould on the surface of the graphene nano-film is plated, which can greatly enhance the mechanical property, the surface of the mould and the mould fast heating or cooling, improve the product quality, and prolong the service life of the mould.
