Extrusion trends,technology and the increasing representation of Chinese firms

摘要

Basically,extrusion machinery hasn't changed much in 25 years or more,and what little has changed is not overly critical.Synchronous torque motors (gearless) - although they work well - will appear on some new lines,but maintenance people won't know about them and the old ones - and they are not so old as that - still work just fine.
