Nitrogen Hot Pressure

Nitrogen Hot Pressure

The NHP solution is a new hot forging technology for brass and other materials requiring high blow frequencies. It is a low-cost, innovative solution using the die lubrication system.

Traditional systems use compressed air to coat the die with graphite oil, which has a lubricant effect. However, the presence of Oxygen in the air promotes partial combustion of the graphite oil upon coming into contact with the hot surface of the die.

With the NHP technology, compressed air is replaced with Nitrogen, which yields the following benefits:

  • Longer die service life;
  • Less fume in the working environment;
  • More effective die cooling and improved production rates;
  • Less localised wear;
  • Reduced graphite oil consumption and better lubrication;
  • Easier cleaning operations.
