Project background: I am working on a project where i need to weld plastic using ultrasonic transducers.

Problem: Since I'm still learning engineering, I have a hard time figuring out what all the factors are in order to choose the right transducer.

What I've done so far: I have searched the internet to find information regarding this subject, but due to (what seems to me) the wide area of knowledge needed, I haven't found anything that I properly can comprehend.


Basically: What do I need to take into account when choosing a transducer?

Not-so-basically: I suspect that the properties of the material certainly affects the welding process, so here comes a sidequestion: what properties of the material do I need to know in order to calculate/decide which transducer to use?

    $\begingroup$ @MahendraGunawardena not really actually, except of a couple of other unanswered questions and some wikipedia articles. Thank you again. I appreciate your guidance. $\endgroup$ – vaid Apr 15 '15 at 23:44

    $\begingroup$ I'm downvoting because I think that you should ask an ultrasonic welder vendor, not Engineering SE. If you discuss your exact application (dimensions, materials, etc) with a vendor, they would be delighted to recommend something to you. Don't make the mistake of thinking that because you are a student you cannot call up companies and ask them for engineering advice about their products. $\endgroup$ – regdoug Apr 17 '15 at 22:14
