This PME PE 400 is a workshop press — sometimes referred to as a hydraulic press or stamping press — a heavy-duty forming machine used in metalworking and industrial manufacturing to cut, stamp, bend, or shape material under high controlled force. PME is a specialist manufacturer of mechanical and hydraulic presses, supplying equipment to industries including automotive, sheet metal processing, and general metal fabrication.
At the heart of this machine is a nominal pressing force of 4,000 kN, making it a substantial piece of production tooling suited to demanding forming operations. The ram stroke is adjustable in increments across the range of 30 to 160 mm, with an additional ram adjustment of 180 mm, and a die installation height of 660 mm measured at maximum stroke with the ram at bottom dead centre and fully raised. The throat depth is 515 mm and the clear distance between the rigidly welded tie rods is 1,345 mm, giving useful working space around the tooling area. The table clamping surface measures 1,700 x 1,000 mm and sits at a height of 1,005 mm above floor level, while the ram clamping surface measures 1,100 x 800 mm and includes a pin bore of 65 mm diameter.
The drive system is powered by a 45 kW main motor. In standard configuration the press runs at up to 45 strokes per minute at idle, and an infinitely variable stroke rate option allows the speed to be set anywhere between 10 and 60 strokes per minute via an ABB frequency inverter, giving operators precise control over the production process. Stroke adjustment and ram adjustment are both fully automatic.
The control system is built around a SIEMENS S7-300 PLC and features a TFT colour touchscreen with an electronic cam controller, die management, and die protection. The colour touchscreen visualisation provides clear operational oversight, and the system includes die data management, counting systems, and data transmission via Profibus. Press safety is handled by a redundant safety control with self-diagnosis capability, delivering plain-text status and error messages. A swivelling main control console adds flexibility in operation. Operator protection at the front of the machine table and die area is provided by a LUMIFLEX non-contact safety guard from BWS, mounted on the tie rods.
The machine stands approximately 4,325 mm tall and weighs around 33,000 kg. This used example was built in 2018 and is currently located in Germany.
