Barrels
Nordson XALOY invented bimetallic
cylinders more than 80 years ago
and continues to lead the way in
development of improved alloys
and production processes.

Nordson XALOY X-800 and X-102 barrels meet the needs for wear and corrosion
resistance for more than 90% of all extrusion requirements.
Strong and straight
The structural shell of Nordson XALOY
bimetallic barrels consists of a
microalloy steel that maintains
high strength and straightness
after casting of the wear-resistant
alloy lining. Unlike some barrel
manufacturers, Nordson XALOY can
produce long barrels – up to 240
in. (6.1 m) – without resorting to
butt welding. The benefit to you
is a stronger, straighter barrel
with no seams to trap polymers
that can degrade and
contaminate your process.

Test conditions: The German
Plastics Institute, Darmstadt
Germany, used standard molding
equipment to inject 10 kg of
nylon and polycarbonate
materials containing 30 and 50%
glass fibers through a 0.5 mm Ø
orifice in test specimens made of
the barrel alloys.
