Ornerynorsk, We're actually inquiring with two ultrasonic welding equipment makers, since they would know best whether the taller e/d profile would be suitable. Thanks.

MintJulep, Thanks for the reply. The ultrasonic welding would be preferred because it's a cleaner process, even though capital investment is significantly greater. However, as mentioned, if the energy director cannot be correctly molded, then it would defeat its purpose. I'm weighing between...

Hello, I have an ABS part with a standard energy director profile (per ultrasonic welding equipment maker Dukane's recommendation) that the plastic injection molder indicated that they cannot produce. The profile is a right triangle, where the base is 0.5mm and the height from center of base to...

Dr. DeArmitt, Thank-you for your quick reply. This device could be used outdoor, but it depends very much on the user. I do believe the device would experience much more to the mechanical stress cycling as described than environmental/thermal stresses. This material would be used on a...
