Sonotrode calculator

Sir
I need a Sonotrod for a 450 x 155 MM freezer door in the refrigrator. It is 2 piece Gpps plastic injection door. We have 20Khz branson machines. they are telling us to weld 6-8 times by making 160 x 40 x 140 mm tall sonotrod off coarse it need to be tuned and calculated.
Why this can not be weld by one sonotrod? I like to get a controle of this calculation in our own hand rather than waiting outside help. How we can do it? What we need to test the frequency ? what we need to calculate the maximum size of sonotrod we can use?

Hi Chris,

I love the calculator, but really need it to work with conical profile horns. Any chance?

Thanks

Hi there,

I used your sonotrode calculator, it is very useful. I have an application whereby my 50W transducer have to have a horn of about 12mm radiator diameter. The calc says the diameter ratio is too large, could I make two steps like 45mm to 24mm and the next step is from 25 to 12mm? It finally would look like a full wave. Or should I have to go for exponential horn?

Thanks

For anyone interested, the formulae used and the assumptions behind them are now available.

To get them, first select your analysis options and then click Help -> Formulae

Hi Chris,
I am using Mozilla 1.7.2. on w2k.
The sonotrode calculator doesn't seem to work properly with my mozilla.
When I click on a top level menu (for example Material) I can see the menu, but If I try to click on a sub-menu (for example MaterialAluminium) nothing happens (the sub-menu doesn't appear).
Could you try to solve this problem?

Ciao Valerio.
