HF welding
hello-
A bit of background... For my senior project, I have designed a two stage parachute deployment system for a low altitude rocket. Together with 5 others, we spit the tasks up into airframe, payload, simulation, and recovery (my task).
For one of my stages of deployment I am using a non-pyrotechnic alternative system utilizing C02 and an inflatable bladder. I intend to use an inflation device from a life preserver, and have contacted the manufacturer of the inflator. In response he told me:
<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote »</TD></TR><TR><TD CLASS="quote">Please note that you need to have a HF welder in order to weld the PU sealing ring onto a suitable inflatable pouch/bladder.</TD></TR></TABLE>
I have never heard of HF welding, the only information I came across was when I googled it. Where can I find someone to HF weld, is that rare?
Any help you can give me would be greatly appreciated. I have a design review coming up and I need to present my idea to NASA because they are being so kind as to provide their launch facility to us
Thanks in advance

Re: HF welding (krustindumm)
yeh im pretty sure its plastic. I googled 'pu sealing ring' and it popped back PTFE...
Is there a way around this? I dont have access to an HF welder. I bet that I can do somethin else for my application.
Sweeden is like 12 or 14 hours ahead of us? Mayyyybe they are waking up to go to work and they will email me back before i got to bed tonight
thanks for the reply

Re: HF welding (B18EG6)
Okay I got this in a reply
<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote »</TD></TR><TR><TD CLASS="quote">c/ The Hammar inflator consist of 3 parts - one operating head on the outside, one back plate that holds the Co2 cylinder and is inside the inflated bag and a sealing ring that you weld into your inflatable bag. The sealing ring has to be welded into the bag and we can provide a simple tool for that, but you have to have a good HF welder to do the work.</TD></TR></TABLE>
does this help at all lol
