Hi everyoneI am manufacturing the plastic injection machine, as a project to motivate students of a university to experiment with the recycling of plastics. And I was trying to calculate the injection pressure of the machine, but I don't know how does anyone have any formula to calculate?I know that maybe it's something very variable but I just need something approximate or an example of the calculation please I found on this page it says that the injection pressure is 45 bar: https://community.preciousplastic.com/academy/build/injection but can someone tell me how that calculated please? if someone can help me I would be very grateful
