  This is likely to be the plant in Washington state.
  
  Warning signs say "HOT" confirming this is a heat process.
  
  There is a cart with manufactured parts. The cart is fitted with thermocouples which are wired into the Quality Assurance console at right. The parts get rolled into the chamber and heated to some specification, The Quality Assurance console surveils local tempeatures to check that heat is applied to meet a specification. It looks like 3 sets of paper charts are created: one in the Quality Assurabce cart and two others in the chamber's control console (left).
  
  The Quality Assurance console may also contain a data logger which would print thermocouple temperatures on what looks like an adding machine tape. Like the strip charts, they prove the parts got the heating in their manufacturing specification.
