How do I make the thread of this plastic bottle? Must I have a bottle of embryo in it?
Industrial oil, then the most suitable material is PP or PE., hollow blow, so if you are customized bottles, the mold costs are saved a lot, I'm doing plastic bottles, hollow blow is
What can be done is that one step blowing, with hollow blow molding machine, usually with PE raw material to blow, there are many such blowing bottles.
Simple said is the raw material into the machine after melting screw push out the formation of a tubular, this is probably understood as preform mould for direct blow on the line, not PET as a first injection tube and then blowing into a bottle to processing.
