Abstract:
To provide an injection device, a resin product manufacturing device and a method for manufacturing a resin product which can improve productivity of a resin product.SOLUTION: An injection device 30 includes a first barrel 50a, a first conveyance screw 60a for feeding a molten resin R to a downstream side while rotating, a second barrel 50b, a second conveyance screw 60b, a control part 71 for controlling the first conveyance screw 60a and the second conveyance screw 60b, a storage part 80 for storing a molten resin R, and a nozzle 90 for injecting the molten resin R. When the molten resin R is stored in the storage part 80, the control part 71 rotates the first conveyance screw 60a at a first rotation speed. When the molten resin R is injected from the nozzle 90, the control part 71 rotates the first conveyance screw 60a at a second rotation speed. The first rotation speed is equal to or lower than the second rotation speed.SELECTED DRAWING: Figure 3
