METALPRESS Metal briquetting presses

Metalpress 600 EVO briquetting press

This is the briquetting press with excellent performances for industrial applications.
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 advantages of our products

Reduction in volume –90%  - CO.MA.FER. Macchine Srl

Reduction in volume –90%

Briquettes allow for sensibly reducing the bulk (depending on the type of material), making work environments considerably more organised and efficient. You can use new spaces to store products and for the production lines.

Lower handling/transport costs –80% - CO.MA.FER. Macchine Srl

Lower handling/transport costs –80%

The transformation of metal scrap and chips into compact briquettes ensures easy and practical handling, thus reducing internal and external transport costs (use of the forklift truck and, consequently, the time operators dedicate to collecting scrap).

Lower recycling costs –70% - CO.MA.FER. Macchine Srl

Lower recycling costs –70%

The lower transport costs for scrap have a direct impact on the sales margin at the collection facilities. Compacted scrap can constitute a valuable source of income.

Lower environmental impact - CO.MA.FER. Macchine Srl

Lower environmental impact

Briquettes allow for reducing the environmental impact due to the conditions and state of the container or collection facilities, which are often not in a good state.

Lower environmental pollution –70% - CO.MA.FER. Macchine Srl

Lower environmental pollution –70%

Thanks to briquettes, the number of container voyages can be drastically reduced, resulting in 70% less fumes released into the atmosphere for transporting scrap to the collection facilities.

Increase in value and yield during melting +90% - CO.MA.FER. Macchine Srl

Increase in value and yield during melting +90%

Briquettes intended for foundries have a higher commercial value compared to chips, as during the melting phase their yield increases sensibly by up to 90% compared to chips, depending on the type of material. Their essential characteristic lies in their extremely high compacting pressures, which makes them qualitatively better compared to simple chips exposed to the elements and subject to oxidation, reductions and shrinkages. Moreover, thanks to their far lower percentage of oils compared to damp chips, which require pre-treating, they can be loaded immediately into the melting furnaces and crucibles, resulting in considerably shorter times, significant energy saving and a considerable reduction in the risk of particle deposits on the walls of the furnaces and crucibles.

Recovery of any oil present +20% - CO.MA.FER. Macchine Srl

Recovery of any oil present +20%

Metal shavings can contain a significant amount of high quality and very expensive oil. During pressing it is possible to recover approximately up to 20%, considerably reducing the purchase cost of the new oil.

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 built with thick sheets and tubulars for superior resistance to stress that has been arc welded and powder coated. In addition to its support function, it also acts as the oil tank for hydraulic components. 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

Highly reliable 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 and a flush steel wheel stirrer on the bottom that rotates by means of a Brevini gear motor, feeding material into a fixed chamber containing a moving drawer.


Box unit - CO.MA.FER. Macchine Srl

Box unit

The box unit has been projected with excellent build quality and reliability criteria. It is composed of a hydraulic cylinder with lapped housing and Parker seals, whose position is detected by proximity switches and mechanicallimit switches to optimize the exchanging time of the electrovalves). It activates the adjustable moving drawer to portion and pre-compress the material, from the loading hopper to a compression chamber.

Compressor unit - CO.MA.FER. Macchine Srl

Compressor unit

The compressing unit has been projected with excellent build quality and reliability criteria. It is composed of a hydraulic cylinder with two coaxial sections for maximum operating speed and optimisation of hourly production at the same installed power, featuring Parker seals, (whose position is detected by proximity switches to optimize the exchanging time of the electrovalves), and a piston rod (in K100) to compress the material inside two sleeves (the front one in K110) inside the compression chamber and shape 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

State of the art IP 55 high technological and functional electric control panel equipped with brand new Eaton PLC (Industry 4.0) for the electronic control of the production process able to connect with computer's systems and a digital thermostat for the oil temperature.
