Nylon casting differs from injection moulding
or extrusion in that it produces a product by polymerization
right in the mould, whereas the other processes simply reshape
a pre-polymerized resin.
EXCELLENT CHARACTERISTICS
Polymerizing in the Mould produces a material
with higher molecular weight and crystallinity, and therefore,
better dimensional stability, easier machining, and higher
compressive and tensile strengths than those achieved by extruding
or moulding.

SPECIAL GRADES
Additives such as plasticizers, lubricants and heat stabilisers
can be used to modify or improve the material’s performance.

Internal lubricants as used in materials
such as Ertalon LFX to reduce the material’s coefficient
of friction and allow materials to perform at PV (pressure/velocity)
levels five times higher than unlubricated nylons, without
the use of additional oils or greases in application. |
KEY SUCCESS FACTORS
Typically these include large wear
parts used in heavy industry where the material’s
light weight, wear resistance and ability not to damage
mating parts have made it an attractive alternative
to steel and bronze parts.
Typically cast nylons, such as Ertalons,
find greatest use as a cost-efficient replacement for
bronze and in applications involving medium speed and
medium temperatures in rugged environments involving
high wear and high impact. |
|
MACHINING
Cast nylons, including Ertalons and Nylatrons,
allow free machining on conventional machine shop equipment
without the use of coolants. Drilling operations, however,
must use coolant and all tools must be properly ground with
low rake and high clearance angles.
|
|
Tools must be kept sharp to prevent grabbing,
which produces chatter or rubbing, causing overheating, dimensional
instability and possible part failure problems. Machining
tolerances in general are higher than those used for metal
parts. (Please contact your local office for DIN standards.)
