The invention provides a method of ceramic double-color injection molding, and belongs to the field of ceramic injection molding. The method comprises the steps that a male die and a first female dieare assembled, and a first injection material is injected into a first die cavity which is formed by the male die and the first female die in an encircling mode, so that a first semi-finished productis obtained; the first female die is removed, a second female die and the male die are assembled, and a second injection material is injected into a second die cavity which is formed by the male die,the first female die and the first semi-finished product in an encircling mode, so that a second semi-finished product is obtained, wherein the difference between the shrinkage rate of the first injection material and the shrinkage rate of the second injection material is smaller than or equal to 2%; and the second semi-finished product is degreased and sintered, so that a double-color ceramic product is obtained. By the adoption of the method, double-color injection molding of ceramics is achieved, operation is easy and convenient, facilities are simple, structural parts which are in complexshapes and are difficult to process can be formed, the working allowance is low, and the manufacturing cost can be reduced. The invention further provides the double-color ceramic product. The double-color ceramic product is obtained by the use of the method of ceramic double-color injection molding, and is accurate in size and durable. The ceramic materials with two colors are closely combined and are clear in boundary.
