Features

Short Thermo-mechanical Process

ERE has short thermo-mechanical process in material conveying and high efficiency in transferring mass and heat, which leads to obvious competitive edge in low energy consumption and less material degradation.

Low Energy Consumption during Plasticization Conveying

Proved by test and theory, specific energy consumption (SEC) for ERE is lower than conventional screw extruder and close to minimum SEC.

Good Extrusion Stablility

In ERE, there is good linear relation between polymer throughput and rotate speed. The throughput does not change with die pressure, resulting in good stability for sheet, pipe and blow molding extrusion.
