Lectro goes small
but powerful for
surface treating
polypropylene, needed surface
treatment in certain cases. Now,
however, with the increased use
of water-based adhesives, primers,
paints and inks, Bliven said
there is a growing need to surface
treat other types of plastics,
such as styrene, ABS, PVC,
engineering plastics, acrylics,
polycarbonates and more.
The LectroTreat process creates
cold electrical plasma in air
that fl ows across a plastic substrate
to raise the surface energy.
" Treatment of a plastic surface
is required when an adhesion
failure takes place between the
plastic surface and the adhesive
due to low surface energy level
on the plastic surface, " Bliven
explained. " The LectroTreat
process will modify a plastic's
surface to create wettability and
cause reactions on the surface,
such as oxidation, chain scissioning
and some cross-linking, to
create various functional groups
to aid in enhancing chemical
bonding to the plastic surface. "
Surface treatment often is
needed for painting, foaming,
gluing, pad printing, silk screening,
laminating, hot stamping
and labeling.
Founded in 1960, Lectro
serves plastic processors and
decorators with equipment for
downstream blow molding line
automation in addition to surface
treating. Bliven acquired
the company in May 2020 and invested
in additional space, machining
centers and employees.
The company was in the news
earlier this year after stepping
up its build schedule to deliver
a spin trimmer to a bottle producer
whose order had fallen
through the cracks of another
equipment builder.
Now Lectro is showing off its
LectroTreat is safer, more productive
and more cost-effective compared to
traditional surface treating systems like
corona treating, directional plasma and
fl ame treating. "

St. Louis-based Lectro Engineering
Co. Inc. developed the
smallest and most powerful
open air plasma surface treating
system in its 62-year history
and will bring it to K2022.
The unit, called LT2012, is designed
for new applications and
existing product lines where
space is at a premium. The size
of the system is much more compact
and powerful, making it well
suited to replace fl ame-based surface
treating and other methods,
according to Lectro Engineering
Lectro is showing off
its LT2012 unit, which
company offi cials say will
lower operating costs
by eliminating adhesion
promoters and enabling
the use of inexpensive
water-based paints and
inks for decoration.

" LectroTreat is safer, more
productive and more cost-effective
compared to traditional
surface treating systems like corona
treating, directional plasma
and flame treating, " Bliven
said in an email.
Plastic surfaces are known
for having poor adhesion with
most other materials because
they are normally chemically
inert and nonpolar. The modification
of plastic surfaces to
improve adhesion is known as
" plastic surface treatment. "
Traditionally, only polyolefins,
such as polyethylene and
LT2012 unit, which company officials
said will lower operating
costs by eliminating adhesion
promoters and enabling the
use of inexpensive water-based
paints and inks for decoration.
The LT2012 can be used with all
types of molding processes like
injection molding, blow molding,
extrusion molding, thermoforming,
rotational molding and vacuum
forming of plastic parts.
The company's machines feature
a plasma tunnel system
that quickly treats all surfaces
of an object at once. The process
eliminates unpredictable
and possibly dangerous fire elements
and doesn't require slow
and precise detail treating like
direction-type plasma systems.
The absence of an open flame
in the plant also will create a
safer work environment, lower
scrap rates and lower operating
costs and insurance premiums.
" It requires no expensive tooling
or robotics while assuring
you of 360-degree treatment of
your part. These combined features
are unmatched in the plastic
surface treating industry, "
Bliven said.
Lectro Engineering has been
supplying this technology to
the automotive, container, medical,
industrial,
company's
recreational,
housewares
and promotional
items markets with great success,
he added.
The
customers
include Pretium Plastics, Berry
Global, Plastipak, Graham Packaging,
Inteva, Joyson, Yanfang,
Nypro, Sonoco, LyondellBasell
Polymers and Callaway Golf.
