Moving on from automotive metal stamping presses, Autotech next addressed the need for a reliable encoder on the end conversion presses used in the 2pc aluminum can manufacturing industry. This turned out to be a bigger challenge as the vibration caused by these presses was so much that even the plant floors had to be reconstructed every couple of years. This was an absolute encoder application which was not possible through a metal disc, so Autotech first used a shock isolated traditional glass disc, then a plastic disc with maximum separation from optical readers and eventually a resolver based encoder. Autotech encoders provide an accuracy of better than 0.1 deg at 3000 rpm on can manufacturing lines through out the world.
