Touguˇ¦s Edge Position Control (EPC) systems have been serving our customers around the globe for over 20 years. Our EPC is known for its stability, good quality, and cheap price. Recently, there are some imitators in China use our name ˇ§Tougu Denkiˇ¨ and sell imitated products. The low quality imitations often lead to catastrophic results for customers.
Imitation
Defects:
Low
surge endurance
of the valve driving
component causes
malfunctioning.
(Genuine Tougu Denki
products use German
part 420VSSR.)
All
switches are cheap
imitations with
low endurance. (Genuine
Tougu Denki products
use French and Japanese
switches with endurance
of at least 200,000
cycles.)
Imitated
sensor socket has
bad connection that
works randomly.
Imitation
Defects:
"Balance meter"
is missing from
the control panel,
thin
film is difficult
to setup.
Not capable of expending
the ˇ§Center positioningˇ¨
function.
Same defects as
EPC-52 .
Imitation
Defects:
inaccuracy >
2mm.
easily interfered
by ambient lighting.
unable to detect
black net.
Sensitivities of
the two sensors
are different, causing
instability.
metal connector
has bad connection,
works randomly.
Imitation
Defects:
Low optical resolution,
cannot detect the
difference between
single and double
layered films.
Unstable detections
due to mismatching
optical and electrical
characteristic.
External
Differences:
Genuine product uses
high quality made
in USA Vickers electromagnetic
valve (high quality,
ultra quiet, 3 years
of warranty, and guarantee
to work for 15 years)
or Japan
Imitation
Defects:
Electromagnetic
valve creates large
noises, will lose
speed in high speed
operations.
Electromagnetic
valve has short lifetime,
low stability.
Noisy
gear pump.
Low
pump flow, large horsepower
motor, consumes excessive
electricity.
Low
stability pressure
regulator valve, without
ˇ§pressure overload
limitˇ¨, causes motor
to breakdown due to
high current.
