Generally, the control board of injection molding machine has a fast slow knob to meet the requirements of injection speed.—carrier tape injection speed

A large flow oil pump and a small flow pump are set in the hydraulic system to supply oil at the same time. When the oil circuit is connected with large flow, the injection molding machine realizes rapid mold opening and closing and rapid injection.
When the hydraulic oil circuit only provides small flow, various actions of the injection molding machine will be carried out slowly.—carrier tape injection speed
