Quick Die eXchange System

Push-pull system for quick die changes, fixed to a press or mobile

For increased productivity in complete safety

Designed to cater for difficult quick die change conditions, the SERAPID PPS pusher is easy to install on an existing press and allows dies to be handled and positioned accurately, effectively and safely:

  • The operator is totally clear of the hazardous zone of the press
  • Manual control from a control station
  • Guarantees the repeatability of die positioning
  • Makes it possible to guarantee the dies from accidental damage during the transfer
  • Used to change a die in just a few minutes

Fixed or mobile push-pull system

The PPS is simply screwed to the back of the bolster or onto the press uprights.
It can also be fixed to a ball and socket joint or mounted on a cart for on-demand installation. Removable versions are also available.


The system, which is designed around SERAPID rigid chains, pushes the die from the reference position in the press to the collection area outside the heart of the press. In the other direction the chains pull the die from its drop-off position to centre it under the press.
The PPS can be combined with the existing bolster and brackets, with existing ramps, die positioning systems and clamps. Thanks to rigid chain technology, the PPS takes up a minimum of space and can easily be installed in most environments.
A PPS is composed of one or two chains driven by an electric gearbox, a push bar with semi-automatic hooks and a frame for fixture to the press. The standard system has a cam sensor which limits the stroke and controls the positions.


All movements of the load are controlled by sensors. This makes it possible to guarantee that the movements are made in the best safety conditions. For example, the operator can only trigger the movement of the chains when the press is stopped and the die released. The standard pusher is delivered ready for full electric control.
The PPS also contributes to the ergonomics and safety of the heart of the press. The operator is moved fully away from the hazardous zone of the press. It makes your die change system a useful and effective one that is fully compliant with the relevant standards and regulations.

TPCH: Horizontal Loading Positioning Table

The T.P.C.H. is a fork lift accessory that fits onto the forks and is designed to install dies on presses.
It is composed of a metal pallet fitted with a motorised rigid chain push/pull system and with one or more die holding interfaces.
Available for maximum loads of 2 tonnes or 4 tonnes, steel/steel movement at 50 mm/sec.

Die stacking unit: the GPO Truck

High precision, repeatable positioning
SERAPID stackers are die handling machines fitted with an original horizontal transfer and positioning system using rigid chains.
They are used to move heavy dies, such as press dies, from storage to the machine and vice versa. The system is all-in-one and easy to handle.

Reliable and effective operations

The dies are taken from a storage rack to the stacker table, they are then transferred to the machine working zone before being pushed into place. In both directions the movement uses SERAPID rigid chains. All the movements are controlled from the operator station.

Easy and completely safe handling

SERAPID GPO Truck series stackers increase your efficiency, your safety, your reliability in the press environment and generally in all workplace areas in which heavy loads need to be transferred carefully and precisely. A GPO stacker also saves you time and money.
A set of safety systems controls the GPO positioning and keeps pushing forces within the nominal limits. This is to guarantee die positioning and transfer performance if safety conditions are met.

GPO Truck types

To cater for the diversity of press environments, SERAPID proposes different types of die-carrying stackers. The smallest handles a 500 kg load, the biggest a 20 tonne load and beyond this weight on demand. All the stackers use lifting mast technology except for the biggest model, which uses a scissor mechanism that supports the load at the centre of gravity. This also makes it possible to handle heavy wide loads.
To further shorten changeover times, we have developed a double
truck concept. This type of stacker allows you to load the die for the next campaign on one of the tables while leaving the other free for the die to be removed. There is no time lost in transit in the aisles. Of course, this solution is only possible for certain die heights at suitable die drop-off heights.

In addition to stackers, we also propose modular supports and racks.
The sizes can be adapted to your specifications. A complete line of optional accessories is also available to adapt our stackers to specific applications.

Stackers can also be built to order. The SERAPID design & development departments are ready to meet any client challenges.

GPO truck increases efficiency, safety and reliability in press operations.

It also helps to save time and money.

Safety sensors monitor the position and condition of the truck, blocking its movement until all safety requirements are met.
