New Xaloy MPX technology can be employed
across the full range of screw diameters and may
be applied to the entire screw or to specific areas.
Standard layer thickness is 300 microns, with
variations depending on the area of the screw.
The MPX screw coating should be used with a
barrel lined with Nordson’s Xaloy® X-800® nickel /
tungsten carbide alloy or a comparable inlay.
Xaloy MPX technology expands Nordson’s
offering of screw encapsulations for high-wear
applications. The Xaloy® X-8000™ coating is a
nickel-based alloy with high tungsten carbide
content that is first applied in an HVOF process,
then fused to the parent metal of the screw to
form a metallurgical bond.
