This is a very high priority project so interested people only bid.
I am looking for a kind of mechanism in which there is horizontal rod made of stainless steel,heater,screw,bearing,Motors,coupling.
Lets simulate with example of pen,
At the tip point there is hole for screw, after that placeholder for the heater(6*6mm) max temp is 250.
When the heater start hitting "tip point to heater" part only should get heated, Rest of the rod should not be heated any how.
So here i am looking for the heat resistance or any magical solid material(metal), Expert suggestion are always welcome.
Person with good knowledge in thermodynamics can dig inside and fulfill the requirement.
Leave a message for further detail, will share detail diagram.
Please note:- there is selenium liquid ,helium gas inside the chamber, so make sure there should not be any chemical process inside.
