Which are the main companies for screen printed electrode machine, which we are planing to procure to fabricate our own screen printed electrodes. Please suggest
Do you want to do your own screen printing using your own inks? You can make your own screens by purchasing the raw materials. We have done this in the past by purchasing the screen supplies from a local art store. For conductive inks, you will probably need to bake out the organic carrier at a high temperature. This is something that most standard screen printers are not doing so you will need to add that to the standard screen printing equipment list (the typical ink dryer will not work). Most screen printing "machines" are designed to print t-shirts. I'm not sure how well that would work for you. You will need to be able to "register" your screens if you are printing multiple layers which can be done either by careful placement of your art while burning your screens or by having an adjustable screen or substrate holder.
I'd need to know more specifics about your application to make more detailed recommendations.
