Ultrasonic welding of PC + 20%GF (Lexan 3412) & PC Lexan 141R
Ultrasonic welding of PC + 20%GF (Lexan 3412) & PC Lexan 141R
(OP)
HI fellow experts,
Just wanted to know if anyone had experience in doing ultrasonic welding between PC+20%GF material and PC. Just that we've been advised by horn manufacturer that there might be issues with welding Lexan 3412 material.
If possible, please advise what sort of problems encountered and if you manage to weld the part, what sort of parameter you use to control part defects in production.
thanks

There is not any memory with less satisfaction than the memory of some temptation we resisted.

I have seen high glass content nylon 6 ultrasonic or vibration welded in a structural part of floating winch handles for yachts. It was the base or 4th side of the main beam of the handle, converting the channel section into a box section. They used between 25 and 45% depending on the length and grip design of the handle. This is made for Lewmar and was previously Titan. It markets under several brand names.
I have also seen 35% glass filled nylon 66 in the body of a steam iron with an integrated water tank. This was developed by Sunbeam in Australia in the late 70s and sold throughout the 80s.

Your replies gave me the confidence to convince the engineers to try out before complaining. Turns out the welding looks good and strong.
