Multi-loop controller tuning

A totally new technology to produce complex metal parts which are partial multi walled at specific areas was developed. By integrating such Rex Ring sleeves into pipe dies the flow channel geometry can be fine tuned to further reduce the thickness tolerances in plastics pipes. This is achieved due to the linear elastic deformation which is realized by the multi-walled flow channel walls. For the first time a pipe die technology is available which enables to establish a close loop control for the total wall thickness of the pipe. It is even possible to establish a close loop control for individual layers of coextruded pipes. But prerequisite for this that it is possible to... [Pg.835]
