The DME Valve Gate Hot Runner System is not to be used in applications that exceed 20000 PSI injection pressure. However please note that if you are approaching 20000 PSI injection pressure, the injection processing window for a typical injection molding machine will most likely become significantly reduced, which may affect your ability to mold good parts. In such cases it is recommended to refer to your injection molding machine specifications or to speak to a technical representative for the manufacture of your injection molding machine.
