Hi,
Could you give some information that How can I measure die swell diameter without using laser sensor.? Could you advise
an apparatus for this aim?
Thanks a lot

RE: Die Swell
Compare the diameter of the die orifice with the extrudite diameter.
RE: Die Swell
Firstly ,thank you very much .I have interested in this area resently.According to the your reply,I think that you are experienced on this area.If you give permission,I want to ask a question.
I will calculate viscosity and other parameters of polymers without using a software.So my job is very difficult,I think.I will mount a pressure thansducer above the die to measure pressure drop inside die.And then I will use bagley correction.But orifice die also can be used for this.What is the better method to measure the pressure drop in capillary ?
