Product Details

Nitrided Screw for Plastic Machines

Nitriding is a heat treating process that diffuses nitrogen into the surface of the barrel wall, to produce a hard surface on the working surface of the component. Depending on the size of the barrel either gas or plasma nitride process is used to give an even depth of hardness.

After Nitriding, a minimum surface hardness of 950 Vickers (VPN), equivalent to 68 Rockwell is achieved with a hardness a depth of 0.4 – 0.6mm. Standard specification.

Nitrided Screws provide good wear and corrosion resistance for general purpose extrusion and injection moulding applications.
