D4 Hammer: Pneumatic Industrial Hammer for Leather Marking and Punching

The D4 Hammer by Danese is a pneumatic industrial hammer for leather marking, serializing and punching, designed for heavy-duty applications in tanneries and leather processing departments.

It is a machine built for users who need constant force, operational precision and long-term reliability. The D4 Hammer can mark up to 10 characters and continuously serialize production batches, ensuring uniform and repeatable results even under demanding working conditions.

Its design follows a practical and proven philosophy: few essential components, properly sized and easily accessible. In production, this is still one of the best ways to make a machine last: less complication, more substance.

Industrial hammer for tanneries, marking and serialization

The D4 Hammer has been developed for operations where leather, hides and soft materials need to be marked, numbered, serialized or punched, even when working with thick materials.

Thanks to its extremely robust cast structure and high-quality components, the D4 Hammer is suitable for continuous working cycles, maintaining precise and consistent striking force over time.

Main applications of the D4 Hammer

  • Leather and hide marking during production processes;
  • Serialization of production batches with numbers, letters or special characters;
  • Punching leather and soft materials without excessive operator fatigue;
  • Combined marking and punching at the same workstation;
  • Industrial identification in tanneries and leather processing departments.

Why choose the D4 Hammer?

  • High marking force: marking force up to 4 tons, using compressed air up to 4 bar.
  • Marking up to 10 characters: ideal for codes, batches, progressive numbering and production identification.
  • Robust cast structure: solid body, deformation-resistant, corrosion-resistant and designed for long service life.
  • Powerful and uniform striking action: ensures precise, consistent and repeatable marking.
  • High operational reliability: suitable for continuous working cycles without performance loss.
  • Simple construction: designed to simplify maintenance, assistance and component replacement.
  • Reduced downtime: quick access to the main components of the machine.

Customized punches for numbers, letters and special characters

The D4 Hammer can work with customized punches, manufactured according to customer requirements. Punches can represent numbers, letters and special characters, allowing clear identification of batches, series, internal codes or production references.

Number changing is fast. For users working with many different sequences, an additional number holder can be used to reduce downtime and make production smoother.

Operator ergonomics and safety

The D4 Hammer can be equipped with a balancer to help the operator work with less effort, or it can be combined with a support base and foot pedal control, according to the workstation requirements.

These configurations make it possible to adapt the machine to the specific operation, improving comfort, safety and production continuity. Less effort for the operator, more regularity for production: an old rule that still works very well.

Simple maintenance and fast technical interventions

The D4 Hammer has been designed for simple, practical and fast maintenance. The machine uses a limited number of main components, easily accessible, in order to reduce downtime as much as possible.

The complete regeneration kit consists of a limited number of parts, allowing quick intervention when required. Before any maintenance or partial or complete disassembly, the compressed air supply must be disconnected and the internal hammer circuit depressurized.

Main replaceable components

  • Pneumatic valve;
  • Cylinder seals;
  • Piston rod;
  • Digital stop;
  • Upper safety guard;
  • Hand safety guard.

Safety note: safety guards must not be removed during operation. The D4 Hammer is designed to be used as supplied, without modifications by third parties.
