The invention discloses a fine simulation silicone product, a manufacturing process thereof and application in inscription rubbing. The method comprises the following steps of firstly, sampling fixing, secondly, inner mold making, thirdly, outer mold making, fourthly, demolding model finishing, fifthly, silicone simulation product making, and sixthly, silicone simulation product finishing. The method further comprises the steps of 7, making of a high-temperature-resisting mechanical dedicated mold heat conduction pressure resistance assembly, 8, high-temperature-resisting mechanical dedicatedmold making, and 9, obtaining of a silicone fine simulation finished product. The characteristic 100% natural texture of a real fish pattern master can reappear, the simulation degree is extremely high, the method is green and environment-friendly, saving and sanitation are achieved, the real fish is replaced for inscription rubbing, durability is achieved, and inscription rubbing use not lower than one million times is achieved, in the national gyotaku, the fish saving number is considerable, durability is achieved, the traditional solid inscription rubbing constraint is broken through, the method can be widely used for various plant roots and stem leaves, insects, shrimps and crabs, and fruits and vegetables, the traditional cultural popularization and inheriting can be facilitated, andthe market prospect is wide.
