In order to know what makes one PCR better than another, we
need to know the important factors regarding a PCR, and not just say to clients
the CET PCR is good. PCRs supply high voltage to the OPC Drum or Amorphous
Silicon Drum in Kyocera, so the effectiveness of been able to conduct electricity
from the steel core rod of PCR through the carbon impregnated rubber at
different temperatures 100% even across the drum as both rotate is crucial. The
CET PCRs are manufactured using only the highest grade raw materials from Japan.
So big deal, what does that mean? The raw materials or powders that are mixed
to make up the rubber or foam we use to make the outer layer of the PCR, is
made from 5 nanometer fine powder, whereas most other suppliers use lower grade
powders of around 50 nanometers. To put this into perspective, and human hair
is between 17 Micron (thin blonde hair) right up to 180 micron for (thick black
hair), 1 micron is 1/1000 of a mm, and a 1000 nanometres = 1 micrometre or
micron. So what we are saying, the powder used to make the rubber for the CET manufactured
PCRs is super, super fine, and to make this fine powder is not cheap, but well worth
it, as it produces a much, much better rubber compound.
Then there is the mixing equipment, which is imported also
from Japan, as it is pointless having the best and finest raw materials but one
cannot mix or knead them properly, so we use especially designed machines to
get the best final product possible, just like the OEMs do, this all takes
considerable investment. The mixing or kneading (for those that do not know
what kneading is, when one bakes bread and mix the dough well, this is known as
kneading).
The resistance or conductivity of the rubber is crucial, and
that it remains stable for long periods is essential for good PCRs, and this is
what we focus on.
Then the PCR production is fully automated where possible,
plus the room temperature and humidity is strictly controlled, as anyone who
has worked with making rubber, polyurethane or any plastic parts will tell you
that the temperature and humidity or water content in the air, greatly affects
the chemical reaction as the rubber is formed, and the hydrocarbons molecular structures
are greatly affected by this, and we have full control and assure absolute
stability in our rubber production for the PCRs.
Every single PCR manufactured by CET is thoroughly tested,
and this I have seen with my own eyes, so not just something someone is telling
us.
Then the outer coating of the PCR is also very important
that it is both durable, and smooth so that residue toner cannot stick to the
PCR, as the most common problem one finds in PCRs giving trouble is because they
get a build-up of toner on the PCR, and higher quality PCRs get less contaminated.
These are but a few characteristics of what makes the CET manufactured
PCRs just so much higher quality. May be a bit technical, but you can always
learn, and remember, it is technicians that are using these PCRs, so this
knowledge should be passed onto them, even if it means nothing to you or to
others.
