METALPRESS Metal briquetting presses

Metalpress 800 EVO briquetting press

This is out TOP 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 oils present - CO.MA.FER. Macchine Srl

Recovery of any oils present

Any costly oils present in the chips that leak during the pressing phase can be largely recovered and reused, with a considerable reduction in the purchase prices.

The components that make our products exclusive

Technical characteristics

Base unit - CO.MA.FER. Macchine Srl

Base unit

Base unit entirely redesigned and optimised on the basis of many years’ experience using a sturdy arc-welded and powder-coated steel structure, complete with liquid collection and recovery well. The base unit is fitted with two IE3 Premium efficiency electric motors, connected to relative Casappa hydraulic pumps to pressurise the system, a hydraulic control unit complete with solenoid-valve module, centrifugal oil-recirculation pump, an oil-filtration device, four air output filters and oil refill, an oil level indicator and an anti-freeze system to prevent start-up with low oil temperature.

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 two coaxial sections for maximum operating speed and optimisation of hourly production at the same installed power, featuring Parker seals and excellent built quality and reliability (with position detected by proximity sensors) 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

Newly designed IP 55 electric control panel equipped with Eaton PLC for complete electronic control of the production process (operating cycle, pressure, oil temperature, and manual/automatic cycle).
