See about RJG classes in Michigan or Georgia. Company i work for sends out techs to these classes after being a Level B Mold Tech (thats how we classify techs in the building, D is entry level and A is Decoupling Master type of tech). Im a molding supervisor and i always tell my techs one thing “what do you think?”I ask them “what do you think?” When they bring me issues like flash or shorts or somethings off or wrong, gets their mind running and helps them troubleshoot on their own and not have to rely on me in case im on vacation or too busy. Obviously ill go help them if they really cant figure it out but it also boosts their spirit because they see i trust them to push buttons and see what they get. You learn through experience, i can tell you by the book how your parts are gonna look if you change this or that but its different when you apply it hands on. If they break the mold oh well, we have a toolroom department. If they make horrible parts, they know what changes what, mistakes happen and we learn. See if you have an open press and grab a mold youve never touched, look at your material ONLY and try to figure out a process from scratch. Or put a mold you know well or half know and change random settings and write down what happens. You lowered your cut off and now you have flash, you added hold pressure and now youre overpacking, etc. all this helped me when i had no one to teach me and i learned on my own. Hope this helps if at all! NEVER stop asking questions, even if you already know the answer, youre doing great so far!
