Introduction of the High Pressure Preformer
The H series (5500 PSI) of High Pressure Preformers have been developed to meet an increasing demand from the rubber industry for machines capable of processing tough or special materials at production rates that are not achievable with the standard range of ES Preformers.

Output Comparison of the High Pressure Preformer and the Standard Preformer
Up to 6 times more output than a standard 210 bar (3, 000 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 ES machine, the effect of this was to reduce outputs to sometimes unacceptable levels. The H series, with its increased compound extrusion pressure up to 380 Bar (5, 500psi) overcomes this restriction and allows production demands to be met without compromise.

Higher Output
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 on our demonstration machine and subject to die size and whether screening is applied or not.
