The invention relates to imitative wood and a manufacturing method of a molded product of the imitative wood. The temperature of a discharging mold opening is adjusted to be lower than the temperature of the tail end of a screw section before conveying of the screw section in a screw extruder or in the conveying process of the screw section in the screw extruder mainly through thermal plastic elastomer (TPE), in the discharging process of the discharging mold opening, the viscosity of the TPE is increased so that the flow speed of an outlet can be reduced, and the TPE flows back and is subjected to friction in the direction opposite to the discharging direction. Grain marks of backflow and friction are generated. Meanwhile, plastic can be drawn and broken along the high-elasticity TPE in the backflow and friction process to be in a wood fiber silk shape, and then the woody fiber silk shape is generated. Then foaming blanks are extruded out of the discharging mold opening. The rotating speed of the screw section of the screw extruder is selected to be adjusted, and the foaming blanks are forced to enter a molding machine to form the imitative wood or the molded product of the imitative wood.
