Hi, I am a very confused design student. I am supposed to be writing an essay on different production techniques including extrusion, injection moulding, blow moulding and vacuum forming. I have a basic knowledge of all of these but don't really know any of them in detail. I have been reading these messages and they have totally confused me! Please could someone help to explain one or all of the above named production techniques in language that I would understand! Thanks very much for your help, jenn
