Did that and searched this forum prior to posting. Need some advice, things to watch out for etc. I need to get it right the first time.

SME offers a course (or at least they did 10 years ago) called Welding of Plastics Clinic: Fundamentals and Practical Applications. It covered all types of plastic welding, ultrasonics are limited to only certain types of parts. Way to much to go into detail here.

Thanks again,

I've used ultrasonics for metal meshes to thick foils but not specifically on plastics, but I know it is an excellant technique for most plastics... depending on composition, surface texture, etc...Like dr_Gallup I recommend Branson/Amtech. If you're in the northeast I'll send you a really good rep's contact info. I also looked at Sonibond (sp?) in the past but found Amtech superior at the time..

go to Branson's website. They have a lot of information that you can download. They also publish a book called "guide to plastic welding" that covers most of what you will need to know.


Try the following link for information downloads.

You can also try the Sonics & materials, www.sonics.com. They are a real engineering company when it comes to plastic welding, not just another products manufacturer.

What specifically are you looking for. My company welds a wide variety of plastic items in our assembly operation.
