How an injection molder works is a question I got recently from a viewer. Here is his full set of questions:
"I’m trying to understand how the injection molding machine works. It looks like a pneumatic piston presses down into a cylinder that is on a sliding axis. Is the force of the piston acting through the plastic the only force that makes the injector press against the mold? Is it a ratio of the piston diameter to the diameter of the injector orifice that causes a tight seal? The force pressing the injector against the mold doesn’t seem like it would be anywhere near the force that is holding the mold halves together presumably it does not leak."
"What is the spring function? Is it to ensure the injector lifts off from the mold when the pneumatic piston is removed?"
Повторяем попытку...
