Hi, I am conducting some experiments with the electroless nickel (EN) coating of the free machining brass (high lead contain material, which is not good for coating but I must use this material). After surface cleaning and etching procedure, once the brass is submerged in the EN coating...

@btrueblood Unfortunately, I do not have the equipment for the electrocleaning. My work is the research in various disciplines and I can devote limited amount of time for this coating resaearch. The industrial procedures for the brass surface cleaning prior to Ni-P coating are complex. I have...

@IRstuff Just to be clear here, by coating quality I mean coating adhesion, wear resistance, etc. But quality is irrelevant here. What I was hoping is that perhaps someone got the Ni-P process kicked off (for the brass) without the electrocleaning step (even with poor coating quality) what...

@IRstuff Thank you for your question. As I mentioned earlier, as long as the process can be kicked off (with simplified cleaning) and I can try certain solutions, it will be ok. Electro cleaning requires extra equipment etc. etc.

Hi, I am conducting the experiments with the electroless nickel plating of the brass (CZ121). I have read a lot of the literature about this process prior to the lab tests. All brass surface cleaning procedures that I have came across involve the electro cleaning (I understand why). However...

@LionelHutz Thank you for the reply. I have added the PID controller into my logic diagram. I send it attached.

@danw2 Thank you for your detailed info on the PLC layout for the scenario. I am grateful, it helped me a lot. I have amended the PLC logic. I send it attached. I will think about the high limit control loops for the system, thank you for your advice. @itsmoked Indeed, the two stage control...

Hi, I would like to provide the PLC control for a scenario where the temperature in a machine, heated by the two electric heaters, is controlled with use of 1 TCK and 2 s/s relays. Please see draft “PLC4” sent attach. The TCK is fixed to the machine and is not in a physical contact with the...

@ScottyUK Thank you for your answer. The heaters are controlled separately through the PLC. Each heater requires separate wires.

Hi, I have 6 cables. Each cable has 3 wires: zero, phase, earth. Each cable supplies 320W 230VAC heater (I have 6 heaters). I am looking for 1 multi pin connector for all these cables for quick plug in/out. Link to example connectors...

@itsmoked Thank you for your reply. I will check these products.

Hi, In search for multi pin connectors dedicated to the TCKs I have came across the following products, which in case someone would look for them may find these links useful: http://www.omega.co.uk/pptst/MTC_CONN.html http://www.omega.com/temperature/pdf/JPCB_TJPCB_RJPCB.pdf...

@danw2 Thnk you for this tip. I will check the TCK jack panel.

Hi, I have 6 K type TCKs connected to the machine component. Component with TCKs is frequently dismantled from the machine for refurbishment. I am lookimg for some quick 'plug in/out' connector/connection for these TCKs. Is there any thing like this avaialble? I can find multi-pin...

@Compositepro Thank you for your reply. This is one of the options, nevertheless, I would prefer little bit more 'tidy' connection. @ScotyyUK The ring lug would be very small 5-10mm diameter. The brass component size is 50mmx59mmx2000mm. Adding fixing tips should not change thermal balance...
