Hello everyone, I'm planning on building a ram style plastic injection molding machine and wanted to know what materials people had good results with for the injector barrel and ram?
I don't plan on using any plastics with chlorine so I'm not sure I really need it to be stainless steel.
I've seen people make them out of aluminum which sounds like it will just gall quickly. I've also seen people use DOM tube.
I have a few pieces of 1144 that I could use. I'm planning to use it mostly for PETG. Any advice on this is absolutely appreciated!
