An egg injection machine is provided which includes a needle assembly, a needle plate assembly, a solenoid assembly and an egg positioning assembly. The needle plate assembly is located above the egg positioning assembly and includes a movable plate (having up and down positions), a stationary plate and a spring located therebetween which is biased to push the movable plate away from the stationary plate. The solenoid assembly is connected to the movable plate and controls the movement of the movable plate. The needle assembly is fixedly attached to the movable plate such that it moves between a retracted position and an injection position as the movable plate moves. The egg positioning assembly also includes a second movable and a second stationary plate, between which the egg is positioned. A shock absorber and a speed controller are attached to one of those latter plates. In operation, the needle assembly rapidly decelerates towards the egg. The movable plate of the needle plate assembly contacts the shock absorbers during this descent which decelerates this movable plate immediately after the needle penetrates the egg shell to a slower velocity. The movable plate then contacts the speed controller which functions to continue the downward movement of the movable plate at this slower velocity, until the needle has penetrated the egg a desired distance. The injecting material is then passed through the needle assembly into the egg and the needle assembly is retracted from the egg.
