Hydraulics are used in manufacturing to transfer and control energy in the form of a pressurized fluid, usually oil, to accomplish tasks such as movement, force and power transmission. Some specific examples of how hydraulics are used in manufacturing include:

  • Power transmission: Hydraulic systems can be used to transmit power from a power source, such as an electric motor, to operate machinery and equipment. This can include things like presses, lift trucks and excavators.
  • Movement: Hydraulic systems can be used to control movement in applications such as robotics, factory automation and in machine tools.
  • Force: Hydraulic systems are used to generate large amount of force to accomplish tasks such as lifting, pressing and clamping. They can also be used to control and apply force in applications such as presses and stamping machines.
  • Position control: Hydraulic systems can be used to control and maintain the position of machine components and equipment. This can include applications such as die casting machines and plastic injection molding machines.
  • Actuators: Hydraulic actuators are widely used to convert fluid pressure and flow into mechanical motion. These actuators can be designed in different forms such as linear, rotary and other special actuators.
  • Lubrication: Hydraulic systems can be used to lubricate machinery, this can help to reduce wear and increase efficiency of the machines.
