Abstract:
QUALITY CONTROL TESTING SINCE 2007
Electronics Inc. (EI) developed a performance consistency
testing program on their A and N Almen strips in 2007 to
ensure they are consistent in thickness, flatness and hardness.
The purpose of EI’s testing program is to verify that the strips
will perform consistently, from lot to lot, from year to year.
TESTING METHOD
EI uses their own custom-built air blast cabinet with a variable
speed rotary table with 39 Almen strip holders, a fixture for
adjusting nozzle distance from the strips, a MagnaValve® for
media flow rate control, and controls to adjust air pressure
and table rotation.
