Some important technical characteristics of making a quality PCR

Week 1 February 2020

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.

Regards and hope this helps and we will cover the molding process in another email
