Extrusion for Metals

Nitrogen shrouding

Gaseous or liquid nitrogen can be used for die shrouding in aluminum extrusion processes to inert the extrusion surface and take heat away from the tooling. Many extruders already use nitrogen but may not be realizing the full benefits of the nitrogen shrouding. Whether you currently use nitrogen in your extrusion process or are interested in using it, our applications engineers can assess your process and help you optimize nitrogen performance to improve production rates, surface finish and die life. We can also reduce scrap rates and increase the pounds processed before a die change is required.

Key Benefits of Nitrogen Use in Extrusion Processes


Protect the extrusion surface from oxidation and improve surface quality


Increase extrusion rate

Cost Savings

Optimize nitrogen usage and increase extrusion die life
