METALPRESS Metal briquetting presses

Metalpress 150 EVO briquetting press

This is the briquetting press apt to be installed in small-medium sized companies. 
This product is a hydraulic machine for recycling metal chips (which, if necessary, can also be shredded depending on the screen mounted on the shredder) from mechanical processes and transforming them into cylindrical briquettes offering considerable advantages. It is designed for being applied to loading units indoors or outdoors.


It is based on a mechanical and hydraulic cycle of high-pressure compacting. A material containment hopper is fastened to a loading bed consisting of a radial loader, which by rotating feeds the material into a box controlled by a hydraulic cylinder that pre-compresses the material before it reaches the compression chamber. A special hydraulic compression cylinder then compresses the material in the sleeve-bulkhead unit.

The components that make our products exclusive

Technical characteristics

Base unit and oil tank - CO.MA.FER. Macchine Srl

Base unit and oil tank

Base unit and oil tank designed and optimised through many years’ experience, composed of a sturdy rectangular frame in square steel piping that has been arc welded and powder coated. In addition to its support function, it also acts as the oil tank for hydraulic elements. Mounted on the base unit is an IE3 Premium efficiency electric motor, connected to a Casappa hydraulic pump to pressurise the system, a centrifugal oil-recirculation pump, an oil-filtration device, an output pipe with air filter and for oil refill, and an electric oil-level sensor that stops the machine in the event of a leak.

Oil cooling unit - CO.MA.FER. Macchine Srl

Oil cooling unit

Oil cooling unit composed of a centrifugal pump that draws oil from the tank and sends it to an Oesse closed-circuit air/oil heat exchanger, optimising cooling and avoiding deterioration and consequent wear of components. This eliminates the problem of continual water consumption and the possible formation of limescale, improving overall machine performance and enabling concrete savings in terms of maintenance.

Loading unit - CO.MA.FER. Macchine Srl

Loading unit

The loading unit has been designed for optimum functionality, with a material loading hopper with flush steel wheel stirrer on the bottom that rotates via a dedicated Brevini geared motor, feeding material into a fixed chamber containing a moving box.


Box unit - CO.MA.FER. Macchine Srl

Box unit

The box unit is composed of a hydraulic cylinder with Parker seals and excellent build quality and reliability (with position detected by mechanical limit switches) that activates the adjustable moving box in order to portion and pre-compress the material, transferring it from the material loading hopper to a compression chamber.

Compressor unit - CO.MA.FER. Macchine Srl

Compressor unit

Compressor unit composed of a hydraulic compression cylinder with Parker seals and excellent built quality and reliability (with position detected by mechanical limit switches) equipped with a press (K100) that compresses the material within a compression chamber formed of two sleeves (K110), thus creating the briquette.


Bulkhead unit - CO.MA.FER. Macchine Srl

Bulkhead unit

Bulkhead unit composed of a bulkhead with hydraulic cylinder of high quality and reliability (with position detected by mechanical limit switches) within which the briquette is held during compression and released once the specific pressure required for briquette formation is reached.

Hydraulic components - CO.MA.FER. Macchine Srl

Hydraulic components

High-performance, high-reliability hydraulic components manage the operating phases of the machine's briquetting cycle. An exclusive block (manifold master) acts as a connection node for all hydraulic components. Movement of cylinders is managed by three Eaton solenoid valves.


Electric control panel - CO.MA.FER. Macchine Srl

Electric control panel

IP 55 electric control panel equipped with digital thermostat for electric control of oil temperature and an Eaton PLC for electronic control of the production process.
