Metalpress 500 EVO: When Quality Production Requires Advanced Control
For medium-sized companies with well-established operations and high volumes
The Metalpress 500 EVO briquetting machine is designed for medium-sized companies with high and continuous volumes of metal chips that require a high-performance system capable of high-quality compaction and advanced control of the production process.This model is available in a version producing 60 mm diameter briquettes for superior compaction quality, or in a 70 mm diameter version for maximum hourly output.
System rated pressure 300 bar: no limits, just performance
To achieve high quality in the specific pressing process, ensuring briquettes with superior density and commercial value, and thus better yield at the foundry.
Two-section coaxial hydraulic compaction cylinder: speed matters
To achieve maximum advance speed optimizing production.
Automatic briquette length adjustment using position transducers: no setup downtime
Thanks to an algorithm built into the program, the machine is able—after ejecting the first briquette—to self-adjust to achieve the length set on the operator panel. This operation is always performed by the machine, and if the briquette’s length varies due to differences in size or type, the algorithm automatically adjusts to maintain a length as close as possible to the set value. As a result, there are no machine stoppages for continuous adjustments, ensuring stable and programmable production output.
New Oil Cooling System with Continuous Off-Line Filtration: Guaranteed Continuous Operation
The new oil cooling system consists of an air/oil heat exchanger, a filter, and a self-contained motor-pump unit. It is designed to ensure continuous oil purification by maintaining the oil at an optimal temperature, preventing overheating, reducing component wear, and consequently minimizing long-term maintenance and machine downtime.

Measurable operational benefits
Briquetting with the Metalpress 500 EVO reduces volume by up to 90%, recycling costs by 70%, and handling costs by 80%. The briquettes offer 50% more commercial value than loose chips and a 90% higher yield in the smelting process. With 300-bar compression, which ensures up to 90% recovery of the expensive coolant—allowing it to be recirculated into the machine tool and eliminating waste— along with automatic adjustment of briquette length to eliminate setup downtime when processing mixed chip types, and the HMI operator panel to keep everything under control, the annual savings on disposal and transportation costs are measurable and substantial.

From hopper to briquette
How Metalpress series briquetting machines transform waste chips into resources in 4 stages.
01
Feeding
A hopper with motorized agitator ensures continuous feeding of metal chips
02
Dosing
A drawer operated by a hydraulic cylinder meters the material into the compaction chamber
03
Compaction
A compaction cylinder compresses the chips at pressures up to 3764 kg/cm2, separating the coolant during pressing
04
Ejection
A gate with specific anti-wear treatments, equipped with a hydraulic cylinder, ejects the finished briquette
