New applications

Hello,
I have been getting lots of useful information from this site.This time I need to know which book will help me to do the sonotrode calculation for steel horns.Can somebody suggest horn dimension and material for gate cutting of moulded component(polycarbonate).
Regards,
Alban

[b]how can i applay ultrasonic to injection molding process
if i want to decrease friction in cavity and runner system how can apply ultrasonic to mold [/b]

Hello Dr. Chris Cheers, or whomsoever else would care to comment on my culinary quandaries.

I am a chef and somewhat new to the world of ultrasonics. I am interested in the feasibility of using a sonicator as part of the chocolate making process. From what I have read thus far it seems as though ultrasonics may be able to facilitate in many aspects of chocolate production. But, to begin this discussion I would like to talk about the possibility of ultrasonic milling on a small scale.

I have a need to join polyethelene and polyester film. They seem to be incompatable, looking for a barrier that may be compatable to both

Hi,

I would like to introduce an advanced technology and new system for Ultrasonic Peening (UP) of materials, parts and welded elements. The development of the UP technology was a logical continuation of the work done before directed on the investigation and further development of known before techniques for surface plastic deformation such as shot peening, hammer peening etc.

Hello,

I'm a technician at Princeton University, and my lab is using quartz and silicon microchips as part of our research. To make reservoirs in our chips, we currently just sand blast the hopes. However, we were hoping to upgrade to something cleaner, more accurate, and more efficient.

Ultrasonic drilling seems like a viable alternative, but I haven't been able to find much information online. We are looking to create holes around 1mm in diameter.

Hi Dr. Chris Cheers,

I'm an Italian student at Politecnico di Milano.

For my final work (thesis) I am investigating the relationship between frequency and quality of ultrasonic welding of metals.

To do this I've to build a magnetostrictive transducer+sonotrode to be tested at different frequencies.

Do you know where I can find informations about dimensioning the different parts of the transducer (diameter of wire, current, dimensions of the pieces of magnetostrictive (Fe-Co) matherial) and sonotrode (something like an old project for a tranducer)?

Forgive my poor English.

Thanks.

Dear Sir,
Young people think they know it all untill
oportunity knocks & then your get a reality
check. This happens to describe how I felt
when my boss decided to give me a bench model
Cavitron 20k Hertz Ultra sonic welder. Well
how does one learn to make custom horns and such? The old manual shows a device that checks horn design but of course this magic box is missing. How can I build horns with a lathe, drill press and mill equipment?
