Hydraulic press
Also called: hydraulic press machine, deep drawing press, H-frame press, C-frame hydraulic press, four pillar press
A hydraulic press pushes a ram with oil pressure, giving full force at any point of the stroke with adjustable speed and pressure. It is used for deep drawing, forming, straightening, assembly, compression moulding and forging, where slow controlled force matters more than speed.
Quick facts
- Drive
- Hydraulic cylinder and pump
- Force
- Full rated force anywhere in the stroke
- Types
- Four-pillar, H-frame (straight side), C-frame
- Size range
- From a few tonnes to thousands of tonnes
- Speed
- Slower than a mechanical power press; adjustable
- Control
- Pressure, speed and dwell time can be set
Typical work
- Deep drawing of cups, shells and tanks
- Forming and bending heavy parts
- Straightening shafts and bars
- Press fitting bearings and bushes
- Compression moulding of rubber and thermosets
- Powder compaction and some forging
Hydraulic or mechanical press?
- Hydraulic: full force through the stroke, controllable speed and dwell, safer overload protection; slower
- Mechanical (power press): fast, constant stroke; best for high-volume blanking and piercing

Questions
- What is a hydraulic press used for?
- Deep drawing, forming, straightening, press fitting, compression moulding and other work that needs controlled force rather than speed.
- Why use a hydraulic press for deep drawing?
- It gives full force with controlled speed all through the long stroke that drawing needs, which reduces tearing and wrinkling.
