Roller surface material -- ink receptive

[Erik Nikkanen]

Hi Cornish,

It is not Rilsan but some nylon that is supposedly less expensive. I will continue to ask the roller supplier for more info but I was a bit surprised that they would not supply the cost info sooner. Maybe they are just too busy.

Maybe it is a sleeve. I was told the thickness was about 0.020".

I will try and get the info again. Thanks for your comments.

I did get the info from the supplier. Not too cheap. Almost $500 to cover the roller. That seems expensive but maybe it is the going rate.

Hello Erik,


Why not have a suitable roller core/shaft, Copper Electro- plated. ??

Yes, that is one of my options. I was also going to lookup flame spray coating of metals such as copper. There are also anodizing processes that might be suitable. It really depends on price. I don't think I need the full performance of copper so other less expensive methods should be OK.

I have confirmed that the nylon coating is done as a flame sprayed coating. Why that should cost so much money to do is a surprise. It is probably sent out by the supplier to another shop.

I have time to investigate this so there is no urgency but the suggestions help.

Thanks.

not sure of the cost but i remember a fellow drag racer talk about having one of his vibrator rollers covered with a ceramic type exhaust coating from a company in the states called Jet Hot. He claimed that it worked well at ink transfer but the coatings durability was still questionable to me as ive not spoken with him in quite a few years. He did mention that it was a bit more affordable that having the roller recovered with Rislan. The are a few different companies here in the states that do these high performance automotive coatings to both exhaust systems and to pistons. In an automotive application the ceramic type coatings offered are primarily used for its thermal properties but i know from personal experience that these coatings are resistant to many solvents.

Thanks for a suggested material.

I think I am going with the sprayed nylon 11 material. Some references say it is the same as Rilsan but the supplier implied it was different. Anyhow it is commonly used and in the end a safe choice.
