Metalpress 900 EVO: The heart of ultra-high-capacity centralized industrial systems.

The top-of-the-line model in the COMAFER range, for those who need the highest capacity

The Metalpress 900 EVO briquetting machine is the flagship model of the entire COMAFER range, designed for foundries, large machine shops, and metallurgical plants with very high chip volumes and a need for continuous industrial briquetting. It produces briquettes with a diameter of 80 mm—the largest diameter in the entire Metalpress series—with an approximate output of up to 1,200 kg/h.

System nominal 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 the set length. 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.

Dual-electric-motor architecture: power always available

to handle higher pressing loads in a stable and continuous manner

Remote Assistance Form: Support When You Need It

The remote support module allows you to connect remotely to the briquette machine to run diagnostics and provide updates.

The Siemens HMI Panel: The Control System an Industrial Plant Expects

The multilingual Siemens HMI panel allows the operator to modify operating parameters using custom recipes, monitor diagnostics in real time, view production status, and automatically track maintenance schedules.

Excellent design for integration into our centralized systems

The Metalpress 900 EVO is designed to integrate with COMAFER’s automated centralized systems, featuring the IL 500P conveyor belt for chip loading and the IL30 conveyor belt for briquette unloading.

Standard Components and Features

The Metalpress 900 EVO is equipped with a base frame featuring an oil power unit, a gearmotor for the agitator, a hydraulic cylinder for the ram, a hydraulic cylinder for the two-section coaxial compactor, automatic briquette length adjustment with position transducers, inductive proximity sensors, a high-efficiency hydraulic system with a cast iron pump, a nominal system pressure of 300 bar, an oil cooling system with continuous off-line filtration, briquette ejection system with a partition equipped with a hydraulic cylinder, dual-electric-motor configuration, electrical control panel with Siemens PLC and HMI, remote assistance module, antifreeze system, and integrated liquid collection tank with an electric pump. Measuring 2020 × 2880 × 1850 mm and weighing 3800 kg, it is designed for heavy-duty industrial environments. The total installed power is 35 kW.

Compatible materials

Aluminum, steel, stainless steel, titanium, cast iron, copper, brass, bronze, nickel, and other ferrous and non-ferrous metals. For non-standard materials, free sample testing is available at COMAFER’s R&D department.

Measurable operational benefits

Briquetting with the Metalpress 900 EVO reduces volume by up to 90%, recycling costs by 70%, and handling costs by 80%. The briquettes offer 50% higher commercial value than loose chips and 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 back 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.
