METALPRESS Metal briquetting presses
Metalpress 150 EVO briquetting press
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.
Operation
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%
Briquettes allow for sensible reduction in volume (depending on the type of material) due to their high pressure compactness rather than the chips. They make work environments considerably more organised and efficient. You can use new spaces to store products and for the production lines.
Reduction in volume –90%
Lower handling/transport costs –80%
The briquettes ensure 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 handling/transport costs –80%
Lower recycling costs –70%
The lower transport costs for briquettes have a direct impact on the sales margin at the collection facilities and can represent a valuable source of income.
Lower recycling costs –70%
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 impact
Lower environmental pollution –70%
Thanks to briquettes, the number of container voyages can be drastically reduced, consequently less fumes released into the atmosphere for transporting scrap to the collection facilities.
Lower environmental pollution –70%
Increase in commercial value +50% 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 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. The chips containing cutting fluids and requiring pre-treating, once briquetted, 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.
Increase in commercial value +50% and yield during melting +90%
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% (with further particular filtering treatments), considerably reducing the purchase cost of the new oil.

Technical characteristics
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.
Loading unit
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, an oil filtration device, an output pipe with air filter and for oil refill, a max. oil temperature thermostat and an electrical oil-level sensor that stops the machine in the event of a leak.
Base unit and oil tank
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 continuous water consumption and the possible formation of limescale, improving overall machine performance and enabling concrete savings in terms of maintenance.
Oil cooling unit
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 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.
Box unit
Compressor unit
The compressing unit has been projected with excellent build quality and reliability criteria. It is composed of a hydraulic cylinder with Parker seals, whose position is detected by a mechanical limit switch), and a piston rod to compress the material in a sleeve inside the compression chamber and shape the briquette.
Compressor unit
Hydraulic components
Highly performing and reliable hydraulic components with the function of handling the operating phases of the briquetting cycle of the machine. An exclusive block (master manifold) is the center of the connections of all hydraulic components. The movement of the cylinders is managed by three Bosch Rexroth solenoid valves.
Hydraulic components
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. The PLC is equipped with pressure discharge programme for progressive start-up. A digital thermostat controls the oil temperature.
