BLISS-BRET PHD Double Acting Hydraulic Presses
Double-acting presses with cushion or ejector, 500 to 25,000 kN
BLISS-BRET PHD double-acting hydraulic presses add a second action from a cushion, ejector or blank holder. They are built from 500 to 25,000 kN in C-frame or H-frame for cutting, stamping and drawing work.

Overview
A second action for drawing and stamping
The PHD range covers double-acting hydraulic presses with standard capacities from 500 kN to 25,000 kN, in C-frame or H-frame designs. They are used for cutting, stamping, drawing and similar operations.
The second action comes from a cushion, an ejector or a blank holder. Presses have one or two main cylinders, variable working speeds and automatic, controlled ram locking at top dead centre.
Force is controlled throughout the stroke, and each press is built to the customer's specification, with more capacity or specific options such as servo hydraulics, quick die change equipment and robot automation.
Applications
Typical PHD applications
The official page names these jobs for the double-acting PHD range.
Close view of a guided drawing die set between ram and bolster of a hydraulic press
Drawing
A blank holder or cushion acts as the second action while the ram draws the part.
Stamping
An ejector or stripper removes the stamped part from the die.
Cutting
Optional shock absorbers for cutting are available for blanking work.
