Upgrades and Retrofits

DEMACO machines last a very long time. The core components retain a very high value almost indefinitely.  As a result this equipment can be periodically updated to 2014 technology.  Customers have told us that in most cases a 1970’s and 1980’s DEMACO extruder is more dependable with lower maintenance load than a new machine from other manufacturers.  With a reasonable investment, upgrading your older DEMACO machine often is your highest value option.


Some of our most popular upgrades:

  • Updated electrical and PLC system with upgraded software
  • Over-bored and extended extrusion units for higher output per RPM
  • High efficiency screws
  • Generation II premixers
  • New feed systems  – volumetric or gravimetric
  • Hardened cylinder liners
  • ControlX automatic mixer control
  • Hydraulic screw push-outs
  • Specialized cutting devices
