Factory Cheap FEP Encapsulated O-Ring to Rome Factories
Factory Cheap FEP Encapsulated O-Ring to Rome Factories Detail:
Encapsulated O Ring adopts special rubber resisting high temperature, F+ plastic and special engineering to compound this sealing product. It not only has low contraction permanent set functions of rubber O Ring, but also resistant heat, cold oil, friction, chemical corrusion and other performances. It can be used in all kind of dynamical seal and static seal widely, meanwhile can replace all traditional rubber and plastic O Ring.

I built a physical deposition chamber, for now it’s just evaporative deposition but I plan on adding a few other variants. The thin films created can be used in many ways.
The chamber still has a ton of space leftover and I have some more equipment coming so hopefully I can do more interesting things.
Sorry there’s no footage of lathing the feedthroughs, they worked nice with a cut o-ring and some heat shrink. Make sure you cut a slot down the holding screw threads to vent behind em. The 2 copper feedthroughs allow (with a center tap) 2 tungsten boats with different metals so I can avoid opening the chamber in a multi layer coating.
The pump down takes about 45 min. to get to 10e-5. I can use a small steel hemisphere with a kf40 hose on the top for use with a secondary high vacuum chamber. The shutter was aluminum flashing with some steel stuck on one side so a neodymium magnet on the outside of the bell jar could move it around without a feedthrough.
This build was really fun
I got everything from mcmaster, K.j lesker, ebay and what I already had
This did cost a bit to make:
diffusion pump- $160
mechanical pump-$140
plate- $270 (ouch!)
valves- $90
gauges- $200
misc vacuum stuff -$120
bell jar – $140 (stupid)
other stuff – maybe $100?

he has done some neat stuff with his setup and a bunch of other things
