rotuba extruders can quickly change the
formulation of the plastics used in its extrusions
directly on the production line. by russ gager
For a rapidly changing market
such as LED lighting fixtures, being
able to extrude a variety of products with subtly different plastic
formulations without necessitating
lengthy changeovers can be a crucial
competitive advantage - one that
Rotuba Extruders has developed
and mastered.
LED lighting fixtures are proving
as popular as flat-screen TVs were
when they became affordable and
significantly thinned out the number of boxy television sets worldwide. For LED lighting fixtures, the

attraction is not only their brightness, but also their economy. They
operate with little heat and use
much less electricity than the fluorescent fixtures they are replacing.
An advantage of the LED - its
brightness - can also be its downfall
if its output is not filtered satisfactorily. The color of the LED light
also can be fine-tuned by the device
itself and by the lenses behind which
it is placed.
For some of the lighting fixture
original equipment manufacturers (OEMs) that Rotuba Extruders

supplies, the challenge is to diffuse
enough of the LED array's brightness through the lens without becoming overpowering or revealing
the LEDs behind the lens. Other
OEMs don't mind if the LEDs can be
seen behind the lens and want their
brightness. The color of the LED has
to be taken into consideration by
the color and texture of the lens.
Some OEMs need different formulations of the plastic in the same
type of lens for different customers.
Before developing this capability,
being able to turn a formulation into
a different one on a dime during extrusion - which is a continuous process - was the holy grail for Rotuba.
"We needed to custom-make individual formulations," President
Adam Bell explains. "You couldn't
just use the same formula for every
