High Pressure Machine Option

Developed to meet the increasing demand for machines capable of processing tough or special materials (e.g. automotive components) at production rates that are not achievable with the standard ECO range.

At 350 bar (5000 psi) it can have up to 6 times more output than a standard 210 bar (3000 psi) machine.

This requirement has become more important where screening or filtering of materials is essential to reduce or eliminate contamination and remove impurities within the material. Although screening or filtering of materials has always been possible with any Barwell machine, outputs levels can be unacceptable.

The ECO H-series, with its increased compound extrusion pressure, overcomes the restriction of reduced outputs and allows production demands to be met without compromise.

The chart indicates the potential increases for various materials, although actual rates for a specific product would need to be clearly defined through material testing and subject to die size and whether screening is applied or not.
