Injection machine electronics detailed list

29/05/2017 at 11:19

Folks please help me,
I plan to order electronics for the injection molding machine. Can you please share with me detailed list of all electronics required. Also please provide ebay or alibaba link of each part in your detailed list.
According to Dave we need:
PID controller
Band heaters
Thermocouples etc…
Huge variety available on ebay, I do not want to order the wrong one. Please share detailed information of the working set of electronics, I will proceed and order according to your links.
With best regards.

@iammashed, here are the electronics that I bought…

PID controller
SSR: Fotek SSR-40DA (it’s capable of passing 40 amperes and an overkill for this purpose, but an overkill also means greater safety margin)
Band heaters: ID 30mm x H 45mm (operated at 220V 0.6A each, i bought 4. they can heat the tube at around 1 deg celcius / second)

I built my PID controller with thermistor myself. That said, I would suggest you find a controller with autotuning. Most controllers can interface with all thermocouples so no worries about that. However, you need to buy a thermocouple which can safely operate in the range. For example, if you want to melt PET at around 260 deg Celcius, get one that works at least up to 300 deg Celcius and the higher the better (again overkill means greater safety… hmm if you forget about the precision and nonlinearity problem)
