1968 ÷ 2018 Machines and components for the automation for over 50 years

The LDP was founded in 1968 as a company for pneumatic cylinders and accessories production. After few time, in order to meet internal production requirements, rotary tables, clamps and presses were designed and built, and the common feature of these products is the use of compressed air as motor fluid. The deep-rooted knowledge of the air - oil systems, brought the LDP to get the first patent in the field, granted by the United States, in 1976. The expertise and research in the application of the air-oil system are consolidated in 1979, when the LDP exhibited at III EMO of Milan the full...

Head Press Hydraulic System Mechanical System HEAD PRESSES Strenght Investment Cost Setting Flexibility Quality of Working Maintenance Drawbacks : till 500 kN. : head press + valves + pneumatic system. : silent thanks to the small impact force on the piece and discharge of a modest amount of air; possibility of use in clean rooms and food industry. : it’s possible to use the working stroke at any point of the approaching stroke. : approaching force and workforce control. Workforce control with a pressure switch or a load cell. Separate adjustment of the approach speed and the speed of work...

The principle of operation of the LDP Press Heads is based on the incompressibility of liquids. Applying the principle of Pascal in an appropriate way, using compressed air as motive fluid, building cylinders with the correct sections, we get a Press Head. Simplifying, the LDP Head Press is constituted by a pneumatic cylinder and a hydraulic cylinder. The pneumatic cylinder has a section of the piston equal to S1, subject to a pneumatic pressure P1, and a stem section S2, subject to a pressure P2. The hydraulic cylinder has a section S3 subject to a pressure P3. For the Third principle of...
