Aluminum extrusion

The aluminum extrusion heated surface of the die, is sensitive to an excess of oxygen content in the atmosphere. This oxygen control is key paremeter for here above concerns.

Liquid Nitrogen can be applied for aluminum extrucsion process which reduces oxygen concentraction at die and controls deposit reaction. The low temperature from liquid nitrogen can extend the operating life of die.
