The element technology items which are necessary to improve the functionality of the mold are the runnerless-system, filling of rubber into a decompressed mold, the cassette-mold, the flashless-mold, the heating method of the mold, the mold surface which prevents deposition from sticking, the washing of the mold, the automatic mold release of the cast, and others.The main technical points that we should aim at in future are as follows:· The complete runnerless-system which is made no runner to leave.· High level molding in the vacuum by transferring its function to the molding machine.· The switching for cassette-mold applications from all function collection design to a function differentiation design.· The expansion of the object of the flashless-molding to the complicated shape products and larger products.· The effective mold heating method by the three-dimensional placement of the heat source or electromagnetic induction.· Lowering of energy of the mold surface that deposition prevents from sticking.· The use of dry washing method without damage to the mold surface.· The direct mold release method of the cast in the complete runnerless-system that cannot catch a runner.
