HD / HD-HF double column press

In regards to press technologies, DUNKES hydraulic assembly presses are configured to meet the various needs of our customers.

The various technologies are configured based on the actual task and the cost budget.

This may involve fabrication processes such as joining, coining, riveting, insertion pressing, extraction pressing, calibration, crimping, or straightening, etc. The various control types, such as NC/CNC controls, servo orientation control for the ram/ejector axis, or simply a straightforward switched hydraulic control for the travel cutoff points are always assigned  accordingly.

Each plant can be upgraded with an on-board memory programmable control of type series S7. Loading and unloading can be accomplished directly in the workpiece pallet or with a sliding table.

Other important aspects of this product segment include quality control by measuring and documenting the force-distance function.
