EPS Foam Densification System

The EPS Densifier by Sebright Products is the pinnacle of industrial-grade equipment designed for the efficient compaction of Expanded Polystyrene (EPS), a material found in various applications from packaging to construction. As heavy-duty “Professional Grade” machines, our EPS Densifiers are meticulously engineered and manufactured in the United States, ensuring exceptional quality and reliability that has been demonstrated since the launch of our original models in 1995. 

Proprietary PLC Operated ADCS (Automated Densification Control System)

The PLC monitors & maintains both the compression ram and the discharge restrictor plate pressures. Proprietary control logic (ADCS) automatically controls the restrictor plate hydraulic pressure to allow expanded polystyrene discharge after compression parameters are attained. Subsequently allowing a wide range of expanded polystyrene material to be processed without operator intervention. Many competing Densifiers have only a manual restrictor plate pressure adjustment which does not compensate for changing foam properties and differences in friction, therefore, results in either low block density or densifier jamming issues unless frequently monitored.

Operating seamlessly and efficiently, the EPS Densifier streamlines the compaction process with a user-friendly interface and advanced features. As EPS material enters the hopper, a sensor detects its presence and relays information to the main control system. Subsequently, the compression ram moves forward, breaking down the EPS into smaller pieces within the compression channel. The press plate then advances, compacting the material into a dense block without the need for heat, thus minimizing environmental impact and energy consumption. 

Our expanded polystyrene Densifiers can operate unattended and as a result, are only limited by the amount of EPS available in the bag hopper and the amount of length for the discharge log of material until it must be stacked. The large feed opening on both the D30 and the D120 Densifier help keep the foam moving and minimize bridging in the bag hopper. The Auto Shear option scores the “log” of EPS block at predetermined lengths allowing less labor and more uniform pallets of material.
