So for the last month-ish Ive been working at my new job as an injection mold operator, which has been rather interesting. I first thought of injection molding as a basic concept of hot plastic gets shot into a mold and gets ejected. But there is so much more that goes into injection molding. There is back-pressure 5 heating zones a TCU which helps the plastic cool in the mold before it is ejected. Then the eject pins extension length and speed. There is probably a lot more as-well but that's just to name a few. There is so many variables into running a injection molding machine, luckily the company i currently work for is teaching me everything and im trying to learn as much as i can (which is slightly overwhelming).The only real annoyance is the plastic smells quite a bit and i read all the MSDS's i can. Something i learned that was a neat tidbit is that plastics like Acetal and TPV, and many other co-polymers is they have alot of nasty stuff in them, and the nasty stuff is only released if it gets above the recommended plastic temperature which is rather important to keep it with a safe range.
On a side note the last place i worked, i liked the people but hated the job and lots of people said the equivalent of "same shit different pot" aka the job you had is going to be alot of the same even if you move. And there mostly right, instead of carbide and kobalt its plastic. The only big diffrence is this place is full time and actually doesn't bully you for wearing PPE, as-well the people there are also rather nice just like the old place.
also any other injection molding operators in the community, and if so do you like the job? as-well as any experiences with it.
also huge thanks to everybody in the thread for helping out and getting me to this point!
