What are nitrided extrusion screws ?

Nitriding is a heat treating process that diffuses nitrogen into the surface of an extrusion screw to create a case-hardened surface. It gives excellent corrosion resistance against humid air and water. It is a case hardening process.

How to make the nitrided extrusion screws?

Barrelize has its own nitriding furnace in-house. The extrusion screw will be put into the nitriding furnace with nitrogen diffused on its surface under a certain temperature and humidity environment. Barrelize nitrided extrusion screw will be put into the furnace for 5 days and nights. After 5 days of deep nitriding, a nitrided layer with relatively high hardness is formed on the surface of the screw.

What's the specification of Barrelize nitrided extrusion screws?

The nitrided layer can reach 0.05-0.07mm. The hardness can reach HV950±50or above, equivalent to HRC68~69.

The general features of Barrelize nitrided extrusion screws: they can improve corrosion resistance and wear resistance.

The main benefits of nitrided extrusion screws: improve the plasticizing rate and increased production.
